Abstract

An apparatus (10,110,220) to transfer gas to or from a liquid has a flexible and oxygen permeable but liquid water impermeable membrane (12,112,212), a flexible and gas permeable spacer (14,114,214), an inlet conduit (16,116,216), an outlet conduit (18,118,218) and a non-rigid restraint system (20,120,220). When used for treating wastewater, an aerobic biofilm is cultured adjacent the planar elements, an anoxic biofilm is cultivated adjacent the aerobic biofilm and the wastewater is maintained in an anaerobic state. A first reactor for treating wastewater has an anaerobic section, a plurality of gas transfer membrane modules, and an aerobic section. A biofilm is cultivated on the surface of the gas transfer membranes in fluid communication with the anaerobic section. Biological reduction of COD, BOD, nitrogen and phosphorous are achieved. In a second reactor, phosphorous is also removed chemically in a precipitation branch.
