water technology daf systems

The Norchem DAF system utilizes a revolutionary U-shaped self-cleaning design that prevents sunken solids from collecting at the bottom of the tank. Each system is engineered to manage greater contaminant loading, reduce sludge volume, meet the most stringent sewer discharge regulations, and improve flocculation.

It is an effective and efficient wastewater treatment process that effectively lowers total suspended solidsĀ (TSS), fats, oils, greases, BOD, COD, and metal concentrations. Each DAF system utilizes one of our modified DAF recirculation pumps that generate ultrafine microscopic bubbles to produce not just a coagulant, but also a load bearing flocculent without the need for an aeration chamber. These flocculants rise to the surface where they are skimmed off the top into our solids chamber. We custom build each of these systems per individual customer requirements. Additional components such as inspection access, odor containment covers, and pH adjustment can be included based on customer request.
