Dairy processing can create high organic loading in factory wastewater streams. For one cheese maker, wastewater contained both suspended and dissolved solids, and COD, TSS and TDS were measured at 8,000 mg/l, 2,000 mg/l and 6,600 mg/l respectively. The loading was equivalent to that of a small town with a population of 3,000 people. With excessive off-site trucking costs and without the ability to land apply wastewater sludge, a viable and economical solution was needed. Simpson provided an innovative, end to end solution involving a dewatering screw, UF and RO filtration as well as a small AOP system and electro-coagulation technology. Ninety-eight percent of the wastewater was made available for reuse at tertiary discharge levels with COD, TSS and TDS measuring 7 mg/l, <2 mg/l, and <10 mg/l respectively. The organic solids could now be readily handled as “green waste” and the clean water was reused in the plant for toilets and general services including outdoor use on lawns and gardens. The Simpson solution provided long-term viability and the organization became a hallmark for affirmative environmental action.
