Abstract

This chapter summarizes the performance of membrane bioreactor, which is a hybrid advanced waste water treatment or reclamation technology system. It also discusses excess-sludge minimization because membrane bioreactor processes are capable of achieving zero emission. Membrane technology in combination with biological treatment is applied to organic wastewaters, a large part of which is biodegradable. Activated sludge process is a suspended-growth biological treatment process, which achieves solid–liquid separation through gravity sedimentation. Membrane separation activated sludge process (MSAS) is the activated sludge processes in which solid–liquid separation is fulfilled by membrane separation. MSAS leads to operation with the high concentration of activated sludge, which can easily absorb shock loadings and give stable treatability. The performance of MSAS may be affected by irreversible changes in the membranes, or by the fouling of membrane surfaces. The membrane separation is usually carried out by a means of ultrafiltration or microfiltration , which do not cause the inhibitive accumulation of salts against microorganisms. A long short retention time with which a typical membrane bioreactor is operated can minimize excess-sludge production.
