Abstract Membrane filtration is considered as a simplified drinking water treatment process,
which can remove organic impurities, as well as metal ions and other ions. Nowadays,
membrane processes are increasingly employed for removal of bacteria and other microorganisms,
particulate material and natural organic matter, which can impart color, tastes, and
odors to the water and react with disinfectants to form disinfection by-products (DBPs).
Recently, there have been several advanced technologies derived from the combination
of biotechnology and filtration with application for potable water treatment. This chapter
describes these techniques which includes biofiltration, membrane bioreactor, ion-exchange
membrane bioreactor, and biological activated carbon adsorption-filtration. Several case studies
in applying biofiltration for DBP control in bench- and pilot-scale are also demonstrated.
