In recent years, membrane technologies combining advantages of biological treatment and membrane filtration have been well advanced in the world practice. Application of an anaerobic membrane bioreactor (AnMBR) for wastewater treatment could be an attractive alternative to recover energy in terms of biogas. The article presents the results of laboratory tests on water treatment in an anaerobic membrane bioreactor with an external hollow fiber module (PVDF). Researches were performed on wastewater of a pulp and paper plant producing various types of technical paper of reclaimed raw materials (waste paper). The anaerobic apparatus operated in mesophilic conditions (36??); the membrane module was installed on a recycling line. In the course of experiments COD volumetric load was increased stepwise, biogas yield and composition, pH change, acetic and propionic acids were determined, main kinetic constants of the process were identified. Due to the membrane module, complete retention of active anaerobic sludge in the system was achieved, the concentration of suspended solids in the filtrate did not exceed 6 mg/l. The maximal effect of COD treatment constituted 93.8 % at biogas yield 359 l/kg COD. The conducted laboratory studies proved availability of anaerobic bioreactors with remote membrane modules for cleaning industrial sewage of complex composition, in particular, recycled water of pulp and paper industry to create flexible and effective wastewater treatment technologies that meet modern requirements for energy conservation and environmental safety.
