Wash Water Recycling Systems

Process Flow & Description

1. Surface-Mount Sump Pump:  Untreated  wash-water is introduced into the system via a 3/4 H.P. surface-mount sump pump.

2.  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 (oil attracting) coalescing 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.

3.  Corona Discharge Ozone Injection:  Water in the cone tank is injected with a high concentration of ozone via a corona discharge ozone injector system, tiny bubbles saturate the water in the  cone tank, killing live bacteria instantly on contract.

4.   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.

5.   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 for effective capture and easy disposal.  The bag filter is suspended on a de-watering tray with drainage returning to the in-ground pits. 

6.   Customized Multi-Media Filter:  *Located at the back of the skid.*  Once the water has been treated for oil and solids removal, it is then pushed through a customized multi-media filter which contains a special media blend to filter out particulates larger than 25 microns.

7.   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.

8.   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.

9.   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.

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

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

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

13.  Poly Skid:  Constructed of hardened polymer to be non-corrosive.  It can also be lifted and moved  with a forklift from all four sides.

14.  Filter Pumps:  Located on the edge of the skid for easy access when maintenance is needed.

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 you application is the first wash-water treatment step, and a critical part of any wash-water recycle system.
