ABSTRACT
The paper presents two case studies of using sequencing batch reactors (SBR) technology to treat pulp and paper effluent in two large paper mills in China. Both paper mills chose SBR systems to treat their pulping and paper effluent to meet stringent environmental discharge limits. This paper provides a brief description of the SBR process, information on the mills, details on the startup of the systems, and the operating data during the first several months of operation. The operating results show that SBR systems are suitable for pulp and paper effluent treatment. The mills are pleased with the simplicity and flexibility provided by the SBR systems.
