The Industries DMP Serves

Historically, slaughterhouses and packinghouses have performed water treatment with a combination of fine screening, sedimentation, coagulation and flocculation, trickling filters, and an activated sludge process. Unfortunately, the chemicals involved have usually been commodity driven—that is, dictated more by price than safety or effectiveness. Acidic and caustic substances such as polyaluminum chloride and ferric chloride have been the viable coagulants chosen for their low cost and the large process water flows. A changing regulatory environment, however, and aging POTW infrastructure have required managers to rethink how best to treat the wastewater leaving their facilities.
