indoor-wash-bay-1280x550.png

Issue: An equipment rental company was expanding and they moved into a new facility
without a wash pad. There was plenty of indoor space but no outdoor space to put in a
new wash pad. The property owner did not want them to cut concrete or substantially
alter the property but our client still needed be able to wash their equipment onsite,
contain the water and discharge it properly to the sewer.

Solution: For a complete wash system, we recommended installing a SPT-10 Clarifier
Oil Water Separator System
, an industrial-grade electric heated water pressure washer
with two portable hose reels, and a portable wash containment pad.
The portable wash pad allows them to wash as much as possible without any major
modifications to the property. They will also be able to move the entire system to a new
facility, if needed. The wash pad was equipped with pedestrian grating along both sides
so that the service personnel can work safely on a dry surface!

Problem: An engineer consulting with a railroad called with an application at a locomotive repair facility. Over time, lube oil and diesel fuel leaked from the locomotives into an inspection pit. Periodically, the oil along with sand and dirt collected in the pit was discharged into a retention pond. The oil was then skimmed from the surface of the pond and the water discharged to the sewer.

The roe skimmer wasn’t quite doing a good job so he asked us for suggestions on how to better treat the water before discharging to the sewer.

Solution: We recommended installing a SPT-20 Clarifier Oil Water Separator System with our standard air-driven pump and control system to treat the water. The clarifier section of the SPT-20 would remove all of the settleable solids while the coalescing media would remove all of the oil from the waste stream.

The SPT-20 did an excellent job of cleaning up the water during the week. The only issue reported was that their sump overflowed with water every weekend so their staff was met with too much water on the pad every Monday morning.

Our maintenance manager trouble-shot the entire system with their staff through Facetime, phone calls, and emails. A local electrician also tried to find the source of the problem since there were other issues at the facility. They tried multiple modifications but the problem persisted.

Finally, we engineered and assembled a hybrid control system just for their particular location and sent it out to them. The control system worked and the system is now fully operational and the client is very pleased.

Issue:  A consulting engineering firm contacted us regarding a wash system for their client that ran numerous grocery distribution centers and warehouses on the West Coast.  The FDA Food Safety Modernization Act (FSMA) rule on Sanitary Transportation of Human and Animal Food required their client to wash the interior of every truck entering their facility in order to keep foods safe from contamination during transportation.

They asked if we could help them design a hot water washing system that could handle multiple users at the same time since most of these distribution centers are very large and busy.  At any point in time, multiple trucks are being unloaded and loaded as fast as possible.

Solution: In response to their request, we worked with the consulting engineers and designed a very effective sanitary washing package that would ensure compliance with the new rule by combining a high-pressure VFD-controlled pumping system with a high efficiency heating system.

For this application requiring 10 stations producing 4 GPM each simultaneously, we provided two 20 gpm @ 1700 psi  pressure washing systems with VFDs and high efficiency heaters. 

The VFD system offered substantial operational flexibility since the system will only utilize the power (speed of motor and pump) to match the output demands. We designed each 20 gpm system to service up to 5 users at 4 gpm each. If there is only one user on the system, however, the pump will provide only 5 gpm, and the motor/pump will only turn at 1/5” speed to meet that demand.  The high efficiency heaters were integrated with the pumping systems to provide the correct temperature water to comply with the FSMA rule.

In addition to the pumping and heating systems, we also provided hoses, guns, reels and holders so their client had a complete sanitary washing package.  The client liked the system so much, they ordered three more systems for other facilities!

portable-wash-pad-car-dealership-1.jpeg

Problem: A car dealer moving into a new facility with a limited time lease. The property owner did not want them to cut concrete or substantially alter the property but the dealer needed to be able to wash dozens of cars per week onsite, contain the water and discharge it properly to the sewer.

Solution:  For a complete wash system, we recommended installing a SPT-10 Clarifier Oil Water Separator System, a cold water pressure washer with a portable hose reel, and a portable wash containment pad. This allows them to wash as many cars as possible without any major modifications to the property.  They will also be able to move the entire system to a new facility at the end of their lease. With their input, we helped them layout the system to maximize their space.

After installation of the pad, however, they noticed the concrete floor slope much slighter than originally thought and that the wash water was not moving off the pad well.  This flat slope left his staff working in standing water and the SPT-10 not being able to process the wash water properly.

To improve this drainage issue, our staff developed a low cost under layer for the wash pad which created a slight slope for the water.  We then installed this under layer and re-piped the in-take piping for the SPT-10 so the wash water flows freely.  The general manager of the facility is very pleased with our systems and service.

oil water separator

Problem: A metals dealer and recycling company had a small wash outside area with a 900 gallon in-ground concrete sump adjacent to it. The sump captured both the wash water and storm water coming off the pad. Contaminants included compressor oil, motor oil, transmission fluid and gasoline.

The company called and asked us for suggestions on how to treat the water before discharging to the sewer. The nearest building to the sump was several hundred feet away and they had very limited area inside it to install an oil water separator.

transportable equipment room

Solution: This was a perfect application for our transportable equipment rooms. To treat the water, we installed an oil water separator with an electric diaphragm pump in a 20′ long container, our TER-20. Since the client was located in a northern climate, we added insulation and a heating system to the TER-20 to guard against freezing issues.

We placed the TER-20 on a pad adjacent to the in-ground sump and it took less than a day to hook up all of the electrical and plumbing lines to make the system operational.

Using the TER-20 saved the client building costs and provided additional storage space. It also allows them the flexibility to move the entire oil water separator system to a different facility when needed.

New Locomotive Wash Bay Pump

A national railroad freight company called and requested a complete overhaul of their 40-year old locomotive wash. This 1970’s era locomotive wash system consisted of three different wash arches – a wetting arch to wet the locomotive, a second arch for soap application and washing, and a third arch with an acid wash for surface brightening.

The wash system was overhauled with to improve the following metrics:

  • Improve the wetting stage process by increasing both water volume and pressure as well as the nozzle design to apply the wetting water on the locomotive; and
  • Improve the soap application process by redesigning the nozzles’ flow patterns and volumes, increasing total flow to the nozzles, and finally adding additional pressure the process.

We started the overhaul process by removing the old soap and rinse pumps as well as the associated wiring and conduit. All of the existing control panels and associated conduit and wiring were also removed. Some equipment was retired in place to reduce demolition, re-piping and re-wiring costs. We then installed the following new equipment:

Locomotive wash bay control panel
Locomotive wash bay stainless steel control panel

Control Panel – A new stainless steel control panel was mounted, which replaced the existing four electrical panels. New conduit and heavier wire was also installed to bring it up to existing codes. The dual electric eyes were re-wired back into the new panel. New liquid level floats were installed in the storage tanks to provide both fluid level control, as well, as provide new a pump shut down safety, in the event of a low water condition in the water storage tanks.

Wetting Pump – A new 15 hp, cast iron pump was installed to supply water to the wetting arch. New, larger PVC piping as well as new heavier electrical wire was installed through new conduit to supply the proper amperage for the new higher horsepower pump.

Soap Pump – A new 15 HP stainless steel pump was installed for the new wash soap arch. New heavier wire was pulled through new conduit to supply the proper amperage needed for the new pump. The new pump was plumbed into the existing PVC piping in the pump house.

Wash Tunnel Nozzles – The existing nozzles could no longer be utilized due to flow and pressure differences from the new pumps. The existing nozzles were removed and replaced with a set of brass nozzles. A total of 42 new nozzles were installed in all three arches.

Rinse System Pump – The existing 100 hp motor and pump were removed and a new 25 hp motor and pump was set in place, aligned, and bolted to the exiting pump base.

Rinse System Control System – A new PLC-based control system housed in a stainless steel panel was installed and integrated with the existing control wires. New wiring was installed from the original motor controller system to the new control panel.

Rinse System Nozzles – The original nozzles, which were sized for the flow from the one hundred horsepower pump, were removed and new brass nozzles were installed.

The entire overhaul took less than a week to install and brought the whole wash system into the 21st century! The client has been very happy with its performance.

Oil Water Separator Forklift Solution
SPT Clarifier Oil Water Separator used for the Forklift Application Solution

Issue: A major forklift manufacturer had an old oil water separator which had failed. The source of the water was a combination of coolants, wash waters, mop waters, as well as a pressure washer water. Over a four-quarter period, the company’s routine certified quarterly wastewater testing results showed fat, oils, and grease levels of 350 to 1270 mg/l discharging to the sewer, which was well in excess of the local limit of 100 mg/l.

Solution: The following year, the company purchased a Wash Bay Solutions SPT-10 to replace the existing separator. Over the next four quarters, the FOG in the wastewater averaged 14.75 mg/l. The actual test results were: 21, 27, 0, and 11mg/l.

Oil Water Separator Solution

Due to the unique design of the SPT unit, it has more opportunity to separate oil and grease than the typical oil water separator. While the SPT is not designed to break an emulsion, due it’s multiple compartments, it can trap and hold back some emulsions. Since it introduction, the SPT has been shipped to many different countries throughout the world. Additionally, many Fortune 500 companies have standardized the unit in their facilities, plants, and processes.

Case Study – University Test Tank

Problem: A technical university had a marine engine testing facility with multiple test tanks in interior and exterior rooms. The discharge from the engines was causing the water to get dirty so that the university was spending between $15-20,000 per quarter hauling water!

The interior rooms had sets of test tanks that could be manifolded together to be treated as one. The outside rooms did not lend themselves easily to manifolding the tanks together. They called us to develop a solution that would allow them to either treat and discharge the water to the sewer or recycle the water with no discharge.

Single Water Recycling System
Single Water Recycling System

Solution: After analyzing available options, we engineered and installed a single water recycling system adjacent to the building that was capable of receiving the water from all of the tanks at different times, removing the oils from the water, disinfecting the water, and returning the water to the respective tank system.

The tank manifold systems in the interior rooms are individually piped to the recycling system with a supply and return line. These attach to a dedicated automated valve system that is programmed to periodically select a specific tank system, draw out the water through the system and return it after treatment to that tank system. The PLC insures this sequence occur on a pre-determined schedule.

Piping drops were installed in the outside rooms so that a technician can manually place an oil skimmer assembly with an integrated suction/discharge hose assembly into any tank and send that water through the recycling system. A remote control panel allows the technician to start/stop the recycling system and to select a time period for the recycling to occur. Processed water passing through the recycle system is free of particles greater than 10 microns in size, substantially all emulsified oils, waxes and other volatile organic compounds.

The engineers at the university tell us that they are saving money and the system constantly “exceeds expectations”!

Port Authority Wash System Case Study

transportable equipment room for port authority

Problem: An international engineering design firm working with a Port Authority contacted us to help them design an equipment and truck wash. The Port had an old wash pad that was too small and old wash equipment that no longer worked very well. The Port needed a larger pad and updated washing and water treatment equipment to accommodate the washing of their existing fleet.

They had the option of either building the wash system with either a closed loop wash water treatment system or a sewer discharge treatment system since they had sewer access but it was quite a distance to the sewer connection.

Solution: Wash Bay Solutions helped the engineering firm develop the design for the wash pad, solids settling system, the wash system and two options for water treatment. For both options, we designed the wash and treatment systems to be installed in a portable transportable equipment room to make it simple and cost effective to install. Requests for Quotations were put out for both options and the electric hot water pressure washing system with the SPT-10 Clarifier oil water separator for sewer discharge turned out to be the most cost effective for this particular location with in the port.

We coordinated with the construction company while they were building the wash pad, settling system and sewer connection line. When they were ready, we shipped up the 20’ transportable equipment room (TER-20) and helped them install it in place and get it up and running within a couple days time!

Case Study – Rental Equipment
portable equipment room

Problem: An equipment rental company specializing in heavy-duty construction equipment needed to build a wash bay for their haul trucks, dozers and construction vehicles. They had limited inside space in a leased building so they needed a to put all of the equipment inside a portable equipment room that they could pick up and move if needed. Due to their location in a remote area with no sewer connection, they needed a closed loop wash water treatment system.

The company called and asked us to build a heavy-duty, self-contained washing system and help them design the wash pad and solids settling area.

Solution: We had worked with this client for years so we were well aware of the washing and solids handling complications associated with heavy construction equipment. With input from the client, our engineers designed a wash pad design and solids settling system that fit into a rather tight footprint.

All of the wash equipment including a closed loop wash water reclaim system, an electric pressure washing system, and a demucking system was installed in a 40’ Transportable Equipment Room (TER-40) and located adjacent to the wash pad. This saved building costs, preserved valuable warehouse space and will allow them to move the entire system to a different facility if needed.
