Robustly designed and manufactured for commercial and industrial washing applications, our heavy-duty, multi-
stage, closed loop treatment systems treats the wash water so it can be used continuously without any discharge to
the sewer or surroundings. Many companies choose to haul this water away, but a more efficient way of removing
this cost is by recycling and reusing the water.

Stage 1 – Solids Settling

Most commercial washing operations produce a lot of solids so the first stage of our filtration process is the solids handling system. We help you develop site-specific solutions to eliminate as many solids as possible before the water goes to the next stage of filtration. Solutions include sumps, basins, trenches or screening systems that are custom-designed sized to fit your facility restrictions, washing processes and maintenance procedures.

Stage 2 – Oils & Solids Separation 

After the coarse solids settling, the water is processed through a multi-compartment stainless steel clarifier oil-water separator, which separates out smaller suspended solids, oil and water. In the first compartment, free oils float to the surface.  In the second section, the stainless steel clarifying plates remove coarse amounts of oil and as much Total Suspended Solids (TSS) as possible.  The angles of the non-clogging plates are 55° which allows solids to slide down the plates into the solids hopper, where they can easily be pumped out.   Next, the water goes through our coalescing media which removes essentially 100% of all free and dispersed non-emulsified oils so the FOG effluent concentration can be as low as 5 ppm.

Stage 3 – Water Filtration, Odor Reduction & Polishing

After the clarifier oil-water separator, the water is pumped though several filtration steps including multi-media (sand, gravel, anthracite), blended activated carbon, polishing filter, and corona discharge ozone. These filters reduce odors and any contaminants to fewer than 10 microns in size, including emulsified oils, waxes, and other volatile organic compounds. Media, carbon, ozone and water storage volumes are typically customized to meet your particular application.
