Wastewater Treatment Systems for Water Recycle and Reuse, Sewer Surcharge Elimination, and meeting Pretreatment Standards
Cost Containment Engineering, Inc. recently received a Water Recycle and Reuse Award from the Texas Section of the American Water Works Association for our custom design of a water treatment and recycle system for the John Deere sales and service facility pictured to the left.
When servicing their customer's tractors and lawn equipment, the equipment is pressure washed with hot, soapy water at this tractor wash station. The contaminated wastewater drains through the floor grate to a nearby underground treatment system. Contaminants include, oil and grease, dirt / silt, grass, gasoline, diesel fuel, and detergents.
Pictured to the right are samples of the untreated tractor wash water (above) and after treatment (below). Laboratory analysis of treated water samples showed BOD (biochemical oxygen demand) < 2 mg/l, FOG (fats, oil & grease) <5 mg/l, and TOC (total organic carbon) of 7 mg/l. Hardness is less than 1 grain, Alkalinity 180 to 240 mg/l, Conductivity 650-800 mg/l (before deionization), Total residual chlorine 1 to 3 mg/l, and pH of ~ 8. The quality of this treated water is very satisfactory for reuse at the tractor wash station. (Click on photos to view enlarged version.)
In summary, the above water recycle / reuse system has been operating successfully since October, 2002. Similar systems can be designed to treat most types of contaminated wastewater for reuse.
These same types water treatment systems can also be employed without recycling the treated water, for example to remove high BOD or oil and grease to eliminate high sewer surcharges, or to comply with stringent pretreatment standards if wastewater is to be discharged into a sanitary sewer system.
