Process and plant for reducing the liquid manure volume arising in animal husbandry

摘要

To reduce the liquid manure (slurry) volume arising in animal husbandry, the liquid manure is circulated through a bed of biological material decomposing in interaction with the liquid manure, such as straw and peat, and through a dewatering device, preferably a reverse osmosis unit. Substantially pure water is taken off. The dissolved constituents concentrated in the residue are simultaneously biodegraded or biologically bound. IMAGE
