Waste profile studies were carried out on milking center (milkhouse and milking parlor) wastes from 24 New York State dairy farms selected in 20 different counties. Data show that farm-generated milking wastes should not be confused or compared with diluted aqueous sewage typical of effluents from dairy processing plants. Presence of high levels of settleable solids explain the rapid failure and fouling of traditional tile field waste systems. While many sanitarians have speculated that milking center sewerage line plugging has occurred because of milk solids and biological sludge accumulation, this field experiment suggests that manure, feed, bedding, and hoof dirt are the principal solids in milking center wastes. |
