Claim:
1. A system for at least reducing the concentration of ammonia from an anaerobic digester capable of producing biogas comprising: (a) an effluent stream, (b) an anaerobic digester in fluid communication with said effluent stream wherein said digester comprises at least one membrane manifold system, (c) a stripping solution tank in fluid communication with said membrane manifold system to at least reduce the concentration of ammonia in said liquid effluent wherein said tank comprises a stripping solution, and (d) a pH measurement and acid addition dispenser in fluid communication with said stripping solution in said stripping solution tank, wherein the stripping solution tank is in fluid communication with said membrane manifold system by way of at least a first hollow flow line and a second hollow flow line, wherein the first hollow flow line is in fluid communication with a membrane manifold entry opening on said membrane manifold system, wherein the second hollow flow line is in fluid communication with a membrane manifold exit opening on membrane manifold system, and wherein said least reducing the concentration of ammonia increases the production of biogas by eliminating the toxicity of high ammonia concentration to methanogens.
