Abstract

The process is suited for the treatment of liquid pig and cattle manure. Process development includes concepts both for regional centralized treatment of liquid manure and decentralized treatment at individual livestock farms. The modular character and the process configuration allow nitrogen and phosphorus elimination efficiencies of about 65% and 90%, respectively, in the first step (preliminary sorptive purification of liquid manure using lignite). Addition of steps 2 (biological treatment) and 3 (membrane filtration) increases elimination efficiencies to over 99%. The manure/lignite compost resulting from the process is plant compatible and exhibits an excellent phosphate and a satisfactory nitrogen effect.
