The present study involves experimentation on the treatment of bio-diesel industrial effluent using a laboratory scale model of Fluidized Bed Bioreactor (FBBR) with three different bed materials viz., MBBR Plastic media, Pumice Stones, high density Foam material. The experiment mainly focuses on the removal of Biological Oxygen Demand (BOD) and Chemical Oxygen Demand (COD) from the bio-diesel industrial effluent. The experiment is conducted for a period over 2 to 3 weeks at daily intervals, till the reactor gets stabilized and a maximum and uniform rates of percent removal of BOD and COD are obtained. The experimental data is analyzed and the results are presented in suitable formats. From the Bio-kinetic study involving reaction rate kinetics and microbial growth kinetics it is observed that, the bio-kinetic reactions taking place in the reactor conform to First order rate of reactions and the Foam pieces are proved to be a good alternative material when compared with that of the Commercially available MBBR (plastic) media
