Wasted product sluicing system for animal stalls - recirculates water with doses of acid to reduce prodn. of ammonia

摘要

In the floor areas (3) on each side of the lines of stalls (4) jets of water spray across the slatted surfaces, sluicing waste products through the gaps between the slats and into gutters which run under the floor to a buffer reservoir (35). The contents of the buffer reservoir are stirred by a turbine on the output shaft of a motor, while the liq. is recirculated by a pump (37) from one end of the reservoir to the ter. other via a pH meter (40). If the pH value is too high, a control processor (41) operates a dosing pump (42) adding acid from a reservoir (43) to the flow through the recirculating pipe (36). @(17pp Dwg.No.1/3)@.
