Worldwide, there are over 2.38 billion monthly active Facebook users as of March 31, 2019 and in the United States, 68% of Americans use Facebook. On average, Americans spend 58 minutes per day on this platform (source: Facebook and Pew Center). Odds are great that your customers are among them, making Facebook Business Page a great opportunity to engage with them. Here are 5 essential steps to creating an optimized business page on Facebook:

STEP 1: Sign up

Go to facebook.com/pages/creation. Here you’ll see two categories, select Business or Brand. To begin, click Get Stated and follow the onscreen instructions, be prepared to fill in the required business information.

STEP 2: Add content

A. Start by adding a profile image. Companies will typically use their logo but keep in mind this image is cropped to a circle so be sure important information is kept away from the corners. Simply click the plus + symbol to add a profile image.

B. The most notable image on your page is your cover image, choose this carefully, this image should mirror your brand identity or brand personality. This image must be at least 400 pixels wide and 150 pixels tall. To add an image, hover over the area to see an edit button appear.

C. Create a username, this is how you’ll tell people where to find you on Facebook. Keep it easy to type and easy to remember, for example your business name or an obvious variation of it. This is also how customers will “tag” you in a post. Example, “Thanks @username for providing me with great customer service yesterday!”

D. Add important company information in your About section, including your contact information, products, hours, location, and company website address.

STEP 3: Create your first post

E. Before sharing your newly created page, make sure you add at least one post. This post can be a current promotion, event, product offer, or information that your customers would find relevant from you or other thought leaders in your industry. Keep your posts content valuable and relevant to your customers; be active and responsive to their comments and questions for increased engagement.

Tip: use images or video in your posts that make sense to the topic you’re writing about. Facebook posts with images see 2.3X more engagement than those without images (source).

STEP 4: Add a call to action

 F. By default, Facebook adds a Send Message button on your page, to edit the button text, hover over it and select Edit Button. Choose the type of button and message that better fits your business. For example, Schedule an Appointment, Free Estimate, or Shop Now – you can then link this button to a specific URL on your business website.

STEP 5: Get Verified

This is often a forgotten but essential step, it shows visitors that you are a legitimate business and gives your brand credibility online. The gray check mark icon next to your business name gives your visitors confidence they are dealing directly with your company and helps to boost your page in search results.

Before applying, be sure to link your business website with your Facebook page in the About section. Additionally, add a link on your business website back to your Facebook page. Ensure all essential fields are filled out on your Facebook About section.

For instant verification, elect to have Facebook call the phone number you have listed on your business page. You’ll receive an automated call that will give you a 4-digit code, enter this code into the box waiting for you on screen and click Continue. You will now see a verified check mark next to your company name.

Alternatively, you can verify by uploading a photo of an official document that shows your company name and address. Keep in mind, this method can take a bit longer as Facebook requires time to review your document.

A Facebook Business Page is essentially a $0 marketing tool that you do not need a marketing degree to successfully integrate into your business plan. Showcase your business personality with authentic content and you will soon find this to be a great tool to grow your business!

This custom mixing station that MLS Packaged Systems engineers designed and built for WaterTec, is a highly-efficient, VFD-controlled component, integral to irrigating greenhouse crops such as tomatoes, cucumbers, peppers and more. The station blends recycled, excess water, which was not absorbed by the plants with treated fresh water for use in the next irrigation cycle. In the mixing tank, fertilizers are added as a balancing acid to regulate the PH of the water to optimum levels. The water is then pumped from the tank, passing through a series of media filters, and out to the greenhouse.

The frequency of station operation is determined by a Growth Management System that constantly monitors the amount of sunlight, greenhouse temperature and humidity, while measuring the amount of water and fertilizer returning from the plants.

The amount of fertilizer in the outgoing water cycle is regulated using electrical conductivity (EC) sensors located downstream of the mixing tank. The treated water will have a consistent low level of conductivity due to the lack of impurities in the water. Adding fertilizers to the water raises the EC. The grower determines the optimum EC level when selecting the fertilizer mix.

Three to seven fertilizer injector pumps cycle on and off to maintain the fertilizer levels at the correct proportions, all this controlled by the Growth Management System. The outgoing PH is monitored by sensors installed downstream of the mixing tank, and activate the acid pump as needed to maintain the selected set-point. A target PH for tomatoes as an example is around 5.

MLS Packaged Systems advance the growing process enabling a continuous, robust crop cycle, whatever the crop. Operational accessibility and flexibility is a key attribute of MLS custom packaged systems.

This large, powerful mixing packaged system was designed and manufactured entirely at Mitchell's Wilsonville facility for our client: WaterTec. Ultimately, the finished, component, four pad system will be used in blending and dispersing combinations of water, fertilizers and other liquids in achieving and sustaining the ideal mixes to support commercial vegetation farming. This style system is not only for tomatoes, but is also used for large scale growing of cut flowers, specialty cucumbers, red/orange/yellow sweet peppers, annual bedding plants, poinsettias and herbs. 

This unit will serve to mix fertilizers into and lower the PH of water that is on its way to the plants. When the irrigation water comes from the well, it is treated and filtered to remove all particulates and organic materials that could affect the plants. Depending on the water quality, there may be no treatment beyond microfiltration, but typically treatment would include RO, ozone gas, pasteurization, or chlorine gas. This water is typically blended with left over water from previous watering cycles that has not been taken up by the plants. That water is filtered and sometimes treated before being blended back with the treated water. This return water is reused as much as is practical to reduce the energy cost of water treatment, to utilize trace fertilizers entrained in the water, and to mitigate high nitrate waste water discharge.

One pump on this skid is called the fill pump. When an irrigation cycle is initiated, water is pulled into this pump through two pipes, one being the return water and the other the treated water. The water is blended by using a modulating valve system to accurately maintain their correct proportion. The fill pump pushes this water into a mixing tank where up to 5 different fertilizers and acid is introduced in direct proportion to the volume of water being pumped to the plants, as measured by a flow meter downstream of a second pump, called the booster pump. This pump moves all the blended and fertilized water from the mixing tank through additional media filters and on to the plants, as well as drive water through EC and PH sensors to confirm correct adherence to the growers fertilizer and PH requirements.

It used to be that growers grew their plants in small isolated blocks within the greenhouse, so that they were assured of a constant, rotating crop in production. Now the common method is to plant a block to 50% capacity and when that crop is at 50% maturity, plant new plants between the existing ones to maintain a continuous crop. This requires two independent parallel irrigation systems as the growing and maturing plants have different irrigation and fertilizer requirements.

A day in the life here at Mitchell Lewis.

One of Mitchell Lewis’ long standing relationships is with the Department of Fish & Wildlife. We are proud to support an organization that does so much for present and future generations providing opportunities to hunt, fish and explore the outdoors. As many of our employees and customers are avid outdoorsmen; we wanted to share one of the recent projects we did for the Department of Fish & Wildlife.

This project was acquired by Industrial Controls Product Manager Darin Malcolm. Darin visited with the Department of Fish & Wildlife to better understand their needs for supplying and maintaining water levels for their fish hatcheries. This specific panel was designed for the Rock Creek Fish Hatchery in southern Oregon. This fish hatchery produces Chinook, coho, steelhead salmon and two stocks of rainbow trout.

The water source for the hatchery are the Rock Creek and North Umpqua rivers. There are five short set turbines that pump out water from these two rivers into the hatchery.

After consulting with our electrical engineering team, Mitchell Lewis & Staver provided a comprehensive solution that will monitor and maintain water levels for both their fish pond and fish trays.

This panel is equipped with 5 – 75HP Danfoss VFD’s that are utilizing a cascade control card which controls a five pump system alternating on a lead lag system.

This is just another example displaying the wide range of expertise and solutions we provide on a daily basis.

We are very proud of the MLS Controls Team and the solutions we provide of customers!

On the road to achieving its goal of becoming a Zero Waste Nation, the island nation of Singapore is committed to promoting sustainable practices within its industrial sector.

West Salem Machinery (WSM), with over 67 years of experience across multiple industries, shredding, grinding, milling, and the mass volume screening of materials, was selected in 2017 to supply the urban waste reduction equipment for the 800 Super recycling company of Singapore. The WSM system grinds urban wood waste, reducing its particulate size to less than 75mm creating fuel for the system. Wood waste which would have typically been shipped off the island, becomes fuel for a boiler and produces energy, which in turn, is used by 800 Super to reduce operations costs. The WSM system consists of a Metso 1000 pre-shredder, a WSM Grinder, a Steinart metal separator, and auxiliary conveyors. Clean wood waste is produced, with consistent sizing, enhancing the performance of a power-generating, steam-driven turbine.

As an acknowledged industry leader in custom engineered electrical switchgear and automation controls for OEM in the “Bio Prep” field, MLS was once again chosen by WSM to develop system controls for 800 Super, Singapore. MLS provided the electrical switchgear for the entire system including a Danfoss MCD500 Reduced Voltage Soft Start for the grinder, and multiple Danfoss FC51 Variable Frequency Drives for proportional control of the conveyors feeding the boiler.

MLS also provided the automation equipment, including a Siemens programmable logic controller to monitor and control the Metso, West Salem Machinery, Steinart, and auxiliary conveyor systems, enabling a maximum production of 50 metric tons of fuel per hour.

As a trusted partner of WSM, MLS provided the engineering, manufacturing, programming, and startup support for the 800 Super “Bio Prep” system.

Vertical Turbine Product Manager

Mitchell, Lewis & Staver Company

Determining overall plant efficiency (OPE) in deep well vertical turbine pumps (VTP’S) (often referred to as “wire to water” efficiency) is essential in our design process for VTP’s at MLS. The OPE determines what the end user will pay in dollars to run his pump. The higher this number is in efficiency percentage, the lower those payments will be.

Pumping plant field efficiency tests are conducted to determine the OPE of a system. This number will help an end user decide whether or not to repair or replace his current system. The power savings often enough will pay for a new system within a few years.

Let’s look at some basic terms we use:

Power can be measured both mechanically and electrically.

Mechanically, power is typically expressed as horsepower (HP). One HP is the power required to lift 33,000 lbs one foot in one minute or 550 lbs one foot in one second.

Electrical power is measured in watts

1000 watts = 1 kilowatt

1 kilowatt = 1.34 HP

1 HP = .746 Kilowatts

Pump HP = GPM x Total head (in feet) / 3960 x hydraulic eff

Pumps and motors, like all machines, cannot convert all of the power supplied to them as useful work.Losses occur from slippage, hydraulic and mechanical friction. These losses can be set to a minimum with proper design.

Efficiency = Power output / power input

Let’s simplify this –

Power is billed to the customer in kilowatt hours (KWH). KWH used is determined by the input HP to the system and read at the electrical meter. The more we can reduce the KWH required, the more efficient the system, ultimately reducing the operating cost to the end user.

OPE is determined by taking the hydraulic efficiency of the pump at its operating point X the electrical efficiency of the motor, minus the losses in the system.

Let’s look at an example –

If a pump is operating at 86% hydraulic efficiency and the motor is operating at 95% efficiency, the OPE will be .86 x .95 or .81% before we add in our losses. Losses typically will be 5-6 % in a properly designed system and even more in a poorly designed system.

A OPE is 75% is considered to be high.

If we picked a pump that was 80% efficient at our design point and used the same motor, our OPE would drop to 71% (still considered good) using the same criteria a above.

Let’s look at some numbers. A system that requires 2000 GPM @ 400 feet of head with 86% bowl efficiency will use 235 bowl HP. The same conditions with 80% hydraulic eff would require bowl 253 bowl HP. That’s 18 more HP to do the same job. 18 HP / .95% (motor eff) = 14.00 KW. At .14 cents a KWH, that’s $1.96 more per hour.If we run our pump 2100 hours per year, that’s over $4000.00 per year in additional operating costs. Over 10 years that’s 40Kplus in savings for a 6% increase in hydraulic efficiency!

Efficiency pays rewards.

Electric motor efficiencies have been set by the Department of Energy (DOE), but pump efficiencies have yet to be set. Our best way to improve OPE is by picking the highest efficiency pump we can, while still meeting our design criteria. Losses in turbine pumps consist of column friction losses and shaft and thrust bearing losses. Column friction losses increase the total head required. Thrust bearing and shaft HP losses increase the load to the motor.

While in the design process for a deep well pump, we look for several factors on the pump performance curve. Obviously, we want the highest efficiency at our operating point. We also want to pick a curve that puts our operating point 1-2 % to the right of the BEP (best efficiency point on the curve).We do this for two main reasons, as the water table declines and as the pump wears, the operating point moves to the left on the curve (towards shutoff).As this happens the pump efficiency actually increases and stays efficient longer as it moves toward BEP and beyond. In deep well pumps, we also look for the steepest curve that meets our other requirements (the highest shutoff head). By selecting the steepest curves, the capacity drops off slower as the pump wears and the water table drops.

We also need to insure our column size is correct and adequate for capacity and velocity while incurring the least amount of friction losses. The same with our line shaft, it must be able to handle the HP required and be suitable for our elongation requirements while keeping our additional shaft HP to a minimum.

As I stated, motor efficiencies have been regulated by the DOE (Dept of Energy), and now must meet the premium efficiency standards set. The DOE is also setting efficiency standards for pumps which will begin to take effect in 2020. The DOE is well aware that the higher the OPE’s we have, the less energy will be consumed and need to be produced. As responsible suppliers and designers, we need to make the best selections for our customers in regards to quality and overall plant efficiencies.A well designed pump system with the highest OPE is in the best interest of all and begins to pay dividends immediately.

I will be glad to answer any questions you may have. I encourage you to contact me.

About 100 miles north of Montana, in the town of Medicine Hat, you’ll find Big Marble Farms, home of a 1.5 million square foot greenhouse, yes, 1.5 million. Even though Medicine Hat is in the heart of the Canadian Sunbelt, with 2000 hours of sun a year, it isn’t quite enough to hold off the Alberta Winter, so Big Marble took their operation indoors.

A green house that has 300,000 cucumber plants, along with 60,000 tomato vines needs quite a bit of high tech equipment to keep their crops happy and healthy. Cucumbers in particular like a very humid environment to flourish. Mitchell Lewis was contacted by one of our valued partners Watertec, out of British Columbia, to help design a system to meet the customer’s needs. Key parameters included system foot print, required water flow and pressure, initial cost, and energy efficiency. To create and maintain the essential level of humidity, the system would use fog nozzles to create a fine mist spray to fill the growing area. The customer’s previous system was falling apart, quite noisy and inefficient.

The packaged pump system from Mitchell Lewis was designed to be a “plug and play” skid that contained the maximum amount of equipment on one single base that only needed to be mounted, wired and plumbed to be operational. The packaged system contained a water storage tank, filtration down to 1 micron, fabricated SS headers, custom UL controls and of course pumps to supply the 50gpm @ 1000psi required. The custom header also included 5 actuated ball valves to open and close depending on which zone of the greenhouse needed misting. Powerful, highly-efficient pumps enable the system to support all 5 zones simultaneously using a single pump at reduced speed. The system provides built-in redundancy and increases energy cost savings.

With the ever-increasing demand for energy and water efficiencies, Mitchell Lewis & Staver and its network of valued partners stands ready to meet these challenges with the latest in technology, engineering expertise and good old fashion experience.

The Portland location of a national motel chain was having severe sewage issues. The equipment in their wet well was old, failing regularly, and causing the site manager a ton of problems. Additionally, the ever-changing waste stream was plugging the pumps, which in turn caused overflow conditions and on several occasions the need for a vac truck.

One of Mitchell Lewis & Staver’s longtime partners, Hillsboro Pump Service was contacted by the motel manager for much-needed help. Mitchell Lewis met with HPS for an on-site review. It was determined that the existing pumps were still a good choice for the required flow/head, but the liquid now contained many “non-pumpable” solids that needed to be addressed. To handle this, the team decided on the tried and true solids destroyer, the Landia Eradigator, a submersible chopper pump, that would also mix the wet well contents with its angled discharge nozzle.

The complete solution is put into action when the pump on float activates. The Eradigator runs for 1 min to chop and mix all wet well contents, it then shuts off, and the on-call, self-priming pump removes the liquid until the stop float is reached. MLS provided the UL control panel as well which required the use of a Danfoss VFD to convert the sites 1/230v power to 2/230v power to run the Eradigator. The MLS Control Panel provided some dry contacts, so the manager could have remote indication of any problems. While only in service for a short time at this point, the station has been trouble-free and the site manager is very appreciative of everyone’s efforts.

The uninterrupted flow of water for irrigation is a paramount concern for any farming operation. The vast and diverse Stahl Farms in Irrigon, Oregon relies on its custom-designed pump system to faithfully deliver Columbia River water to expansive fields, miles away. Unwelcome noises from two of the pumps had Herb Stahl reaching out to his irrigation specialist, Valmont NW., who in turn, contacted the irrigation system experts at Mitchell Lewis & Staver. Upon inspection, it was determined by MLS engineers, that the foreign noises were attributable to the pumps operating at too low of pressure, causing the pumps to operate off the end of their performance curves – resulting in unsettling noises. The trusted engineering experts at MLS bring decades of experience to their work – from custom irrigation system design to remote "house calls", MLS keeps it flowing!

MLS and Polaris deploy jet ring power to save customer and competitor from costly downtime.

Moses Lake WA - Basic American Foods, a major processor of potatoes, was experiencing routine clogging, and inability to self-prime with their existing chopper pumps in their waste pit. The waste stream fluctuates between water with just a few skins and pieces, to large slugs of potato chunks, sticks and dirt. During these large influxes of solids the existing chopper pumps were unable to pull a suction lift, or chop such a high solids concentration at once. A solution was needed that could not only handle these solids, but also “stir the soup” to keep a uniform solids concentration, and stand up to the abrasive sand present in the waste stream.

Mitchell Lewis selected a 15hp, hard iron slurry pump from Polaris to do the job. This pump can handle solids concentrations up to 60%, is made of a high chrome metal for abrasion resistance and came equipped with an externally mounted jet ring to continuously mix the sump and keep the solids even dispersed throughout the water. The jet ring is fed from a separate water source and shoots high pressure water jets to break up large masses of solids.

We are pleased to note, that after two months after installation, the Polaris has been able to keep the self-priming pumps clog free and the system running 24/7.

With increasing demand for a reliable source of potable water, the government of Cameroon in 2015 embarked on an ambitious project to rebuild and replace their insufficient, aging colonial French water infrastructure. The robust, new system will deliver much-needed water to the capitol, Yaounde. Engineers at MLS have designed a powerful, scalable new system, which utilizes some of the existing built-ins, while delivering substantially more water volume to the central civic reservoir. Once completed, the new water system will feature a series of five Goulds vertical turbine pumps powered by US Motors, rated at 1250HP, delivering 6600 GPM @ 581 ft. This project will be completed later in 2016.

Several months back, Mitchell Lewis & Staver provided the Oregon Coast Aquarium in Newport Oregon, several sump pumps and variable frequency drives (VFDs). The VFDs allow the pumps to run at reduced speeds when demand is low, saving energy and money. Working in conjunction with level sensors, the VFDs help the pumps maintain a certain sump level at all times by running the pump at a proper pace and not having them start and stop all of the time. Running pumps at reduced speeds also helps increase the overall lifetime of the pump. Gary Smith, Head of Maintenance for the aquarium, states “We are saving on average $60-70 dollar per month, per pump by using VFD’s, and with the level maintenance process, we never run the pumps dry.” Gary has since added 2 more VFDs to other existing pump controls. Danfoss VFDs are an integral part of powerful and efficient MLS Controls.

Pioneer Pump will continue to be an important, crucial part of business at Mitchell, Lewis & Staver.

In order to meet expanding current and future demand for their popular products, a major dairy in Boardman, Oregon, recently acquired an additional 7,000+ acres of land for dairy cow feed, livestock grazing and potato cultivation. Upgrading their irrigation capabilities is a priority and includes a complete rebuilding of their 18 pump system. Time is of the essence, as these crucial irrigation pumps are offline during the rebuild period. Under this tight deadline, MLS is moving quickly to rebuild the 18, 4 to 5 stage vertical turbines, which operate at between 200 and 500 hp, delivering up to a maximum of 5,600 gallons of water per minute. An engineering challenge, as each rebuilt pump must match the existing discharge head and column. Valmont Industries selected MLS as the best source for the scale and schedule driving this project.

The ability to immediately suppress any dockside shipboard fire is a perennial safety concern for the U.S. Navy. Historically, securing a ready-source of high-pressure water in the event of fire, particularly in foreign ports, has posed significant challenges, sometimes with tragic consequences.

Following exacting USN specs, Mitchell Lewis & Staver created a highly efficient, powerful solution. This month the U.S. Navy will receive the final shipment – 54 vertical, multi-stage pumps in all, from MLS. Each pump incorporates non-corroding, stainless steel or bronze components throughout, and is framed in a custom-designed, galvanized (marine air resistant) frame allowing the pump to be rapidly deployed from either dockside surface or sub-surface vessel. Vessels will carry a pump fore and aft. Each pump runs at 226gpm at 174 tdh, powered by a Goulds Water Technology 46SV 20 hp pump with a Leeson VFD.

MLS worked closely with our business partner Balco to secure this opportunity to proudly serve.

When New Earth of San Antonio, Texas went looking for a heavy-duty, aggressive grinding machine to annually convert 350,000 tons of highly-variable organic waste into high-grade garden products, they turned to West Salem Machine (WSM). Typically, this type of diverse, organically-rich waste including food waste, grass clippings, leaves, livestock manures and tree trimmings ends up buried in conventional landfills – going to waste. New Earth gives it a second, vital purpose.

Lorentz Solar is supplying powerful, "off-the-grid" solutions to remote Ag customers.

Farmers in Turkey faced problems with unreliable grid electricity which resulted in the loss of crops. The solution was the installation of a grid-independent PS40k2 solar pump system. This system provides 1200 tons of water per day from 80 meters below ground level. Being independent from the grid and receiving water reliably with solar energy is a great relief for the farmers.

The REAQUA video shows how in an area with a dry, sandy and hot climate, 5000 head of cattle on an isolated Australian farm are fed. REAQUA installed two LORENTZ submersible pumps which provide year round water to center pivot systems each covering an area of over 40 hectares per pivot.

MLS partners with Lorentz in bringing our Ag customers dependable, power-generating, solar-based solutions. With over 20 years of continuous innovation, Lorentz is an Industry leader in solar-powered, water pumping technology.

The Moscone Center in San Francisco CA is one of the largest convention centers in the state. Moscone West contains the kitchen for the entire facility as well as several bathrooms. The kitchen produces a good deal of food waste, floor debris, commercial dish washer water and occasionally, a rubber glove finds its way down the drain along with everything else. Combined with the bathroom waste, these solids often plugged the standard, non-clog pumps previously operating in the wet well. As the pumps were on rail systems and needed to be cleaned constantly, it became a maintenance headache. General contractor, Koffler Electric, turned to Mitchell Lewis for solutions to the plugging problem at Moscone. Mitchell Lewis having had several recent successes with the Landia chopper pump, was able to select a model to hit Koffler’s desired design specs: (250gpm @ 36ft TDH). The Landia pumps were installed recently and have run “clog-free” ever since.

The Landia Chopper continues to impress here on the west coast. MLS has installed several Landia pumps which continue to perform flawlessly, some for over two years, and not a one has been pulled off line, for any reason….ever.
