DPC 15, Milking Center Wastewater
Item #: DPC-015
All dairy farms produce and then must dispose of wastewater from their milking centers. There is great variability in the quantity of wastewater produced as well as the concentration of contaminants from farm to farm. There are also a number of ways to treat the effluent. Each dairy farmer needs to evaluate the specific situation on their farm to determine the best treatment method for them.
