Recycle Clarifiers for Wash Water Recycle Schematic



Proper Pit System (not shown in picture): Once equipment is washed, the untreated wash water flows into your pit system. Note: A proper pit system for your application is the first wash-water treatment step, and a critical part of any wash-water recycle system. Consult Wilson Environmental or your local distributor to determine the pit system that will work with your application.

Submersible Sump Pump: Untreated wash water is introduced into the system via a 0.5-HP submersible sump pump (included with system, but not pictured), typically located in the sump pit.

A. Clarifier Oil/Water/Solids Separator: As the water flows through the cone-shaped oil/water/solids separator, it changes directions countless times as the water is directed and redirected through cone baffles, with hundreds of square feet of oleophilic-coalescing (oil-attracting) media. Mechanically emulsified oil particles are attracted from the water to the oleophilic media, and then float to the surface. Once on the surface, the oil is skimmed off into an oil decanter for easy disposal. Fine silt and particulates are dropped to the bottom of the cone for easy flushing and disposal of the accumulated solids.

B. Corona Discharge Ozone Injection:
Water in the oil/water/solids separator is injected with a high concentration of ozone via a corona discharge ozone injector system for a "quick kill" of live bacteria on contact.

C. Oil Decanter:
Oil skimmed from the surface of the clarifier tank is captured in a conveniently located oil decanter. Oil can be removed easily for appropriate disposal.

D. Solids Separation Chamber:
Solids from the wastewater stream settle at the base of the clarifier tank. With the opening of a single valve, solids are easily dropped into a bag filter in the solids separation chamber for effective capture and easy disposal. The bag filter is suspended on a dewatering tray, with drainage returning to the in-ground pits.

E. ORP/pH Controller: For longer term control of bacteria, the ORP injection system automatically measures and injects a germicide to control odor by killing odor-causing bacteria. The automated pH control system keeps the water at an appropriate pH level so the germicide is effective at killing bacteria and controlling odor.

F. Control Panel: This NEMA-4-rated control panel makes the equipment simple to operate and is easily accessible.

G. Reusable Polyester Filter:
Once the larger particulates are removed, the water is then filtered through hundreds of square feet of reusable polyester 20-micron filters.

Customized Multimedia Filter (located at back of skid): Once the water has been treated for oil and solids removal, it is then pushed through a customized multimedia filter which contains a special media blend that filters out particulates larger than 25 microns.

H. Activated Carbon Filter: The final treatment stage of the system occurs as the water is filtered through activated carbon which absorbs hydrocarbons, herbicides, pesticides, some metals, and dozens of other carbon-based constituents.

I. Pressurized Water Storage Tank:
Treated water is delivered for reuse at 30 to 50 PSI via a pressurized water storage tank.

J. Poly Skid: The skid is made of hardened polymer to be non-corrosive. It can also be lifted and moved with a forklift from all four sides.

K. Hose Connectors: Designed for easy accessibility and quick installation, the connections are clearly marked.

L. Filter Pumps: Filter pumps are located on the edge of the skid for easy access when maintenance is needed.
