Abstract |
The study was concerned with an analysis of the dairy water budget and an evaluation of the efficiency of a 2-cell lagoon waste treatment system for a modern 130-cow dairy at Holly Springs, Mississippi. The water budget at the dairy was determined by means of water meters installed on the main supply line, the alley flushing system, the milking parlor flush tanks, the prep stalls, the milk-room and the waterers. The water budget was summarized on a weekly basis by means of a computer print-out. The overall treatment efficiency of cell one (reduction in BOD was 62.9%. The overall treatment efficiency of cell one plus cell two was 86.5%. (Modified author abstract) |
