Dairy Wastewater Treatment With IPEC Screens

Dairy manufacturers produce anywhere from 1-6 gallons of wastewater per gallon of raw milk input. This wastewater contains high concentrations of solids, oils, phosphorus and nitrogen.  Dairy wastewater treatment begins with screening out coarse or heavy solids that could damage process pumps.

Beyond the organic materials in dairy wastewater like milk solids, whey, and butterfat, significant volumes of cleaning products involved in sanitation are also found in plant effluent.  These chemical solutions cause varying wastewater pH and present process challenges when it comes time for treatment. Where many wastewater treatment applications follow a prescribed coagulation/flocculation process, dairy wastewater often requires a different approach that better accounts for the tendency of milk products to release noxious odors during equalization.

Every wastewater treatment application is unique.  It has its own set of variables that make having an experienced process designer an absolute necessity.  JWC Environmental’s wastewater process design team has worked on many dairy wastewater treatment applications.  With this wealth of experience we design treatment programs specifically to your project needs.  Whether supplying a single piece of equipment or delivering a turn-key solution, JWC’s IPEC rotary drum screens along with a our SHRED grinders, will improve your unique application’s needs.
