Anaerobic MBR for the treatment of high COD loads

Scope: Paper industry

Results: A specific process was designed for the treatment of an industrial effluent composed of a mixture of strongly colored inks and glues. Due to the complexity of the mixture, different alternatives were evaluated in a series of laboratory-scale studies, after which a pilot-scale study was carried out at the client’s premises. The final process consists of an anaerobic MBR followed by an advanced oxidation process. Together, a sufficient COD removal and complete discoloration (enough to comply with legal regulations) are attained. In addition, the production and seizing of biogas allows to greatly reduce the operating cost.
