DPC 15, Milking Center Wastewater

Item #: DPC-015

Published: 1998

Pages: 40

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.
