Abstract Biofiltration is a mechanism by which microorganism are used to degrade and remove pollutants using a bioreactor. This concept is limited to solid liquid and gaseous pollutants. In this chapter focus is more on the removal of the waste water pollutants.The research showed that biofiltration process has been used in the treatment of municipal wastewater treatment followed by leachate, and various industrial wastewaters such as, textile, dairy, food-processing, baker’s yeast, pulp, and paper. In those studies, high removal rates of carbon, nitrogen, and phosphorus parameters were reported in aerobic/anaerobic conditions using single column biological biofiltration, biological activated carbon filter, sequencing batch biofilter, or multistage biofiltration processes.Biofiltration techniques have proved to be economical and efficient in removing pathogenic microorganisms from wastewater. The current chapter focuses on series of biofiltration systems and their efficiency in pathogenic microorganism removal.This review chapter aims to present a basic understanding of the biofiltration technique and its application toward the treatment of wastewater. The chapter also discusses the application of a variety of biofilters such as anaerobic, aerobic, bacterial, algal, and mixotrophic biofilters for sewage treatment.

Keywords :Biological method, biofilteration , biodegradation, pollutants, wastewater treatment.
