Milking-parlor waste ordinarily consists of feces, urine, small amounts of wasted milk, and a large volume of wash water. The high water content makes it very tempting to consider milking-parlor waste disposal as a separate problem from that of the manure collected from other areas within a confined dairy operation. There is little debate about the way manure should be disposed of, but the same cannot be said for milking-parlor waste. Manure is spread on the land, whereas milking-parlor wastes are disposed of in a variety of ways, e.g., direct discharge, lagooning, or through septic tank systems. The study reported here was undertaken to assess the treatability of a typical milking-parlor effluent by aeration to help determine the most feasible disposal method for the watery waste.
