What criteria should I consider for wash water treatment system designs?
The type of contaminants to be removed from the wastewater plays a big role in determining the type of system needed. Fleet and rental yard wash water typically contains: -Soil and sand -Oil & grease -Heavy metals -Grass clippings and other plant matter Wash pads and containment areas are designed to accommodate the type of vehicles or equipment being washed. They need to be strong enough to support any equipment washed and large enough to capture all wash water. The wash pad should be designed so that rain water runoff from surrounding areas does not accumulate on the pad, and at the same time easy access for all equipment to be washed is allowed. The wash pad is usually designed to work with a specific type of treatment system and is generally constructed of steel or concrete. Grades and drainage requirements are important considerations for contractors constructing the containment area.
