Studies on treatment of sugar industry effluent using inverse fluidised bed bioreactor

Praharaj, B B (2014) Studies on treatment of sugar industry effluent using inverse fluidised bed bioreactor. BTech thesis.



Treatment of effluent of sugar industry is carried out by inverse fluidized bed. Different components of effluent like chemical oxygen demand (COD), biochemical oxygen demand (BOD) and pH have been measured by varying different parameter such as concentration, time of fluidization. The growth of microorganism w.r.t. different parameter has been noted. COD, BOD and pH are observed to decrease with decreasing concentration of the solution. Again values of different output parameters (BOD, COD and pH) are observed to be reduced with increasing timing in an inverse fluidized bed. Microorganisms are allowed to grow and steady state was observed same microbes were transferred to inverse fluidized bed for studying the effect of parameters on its growth. Microorganisms are observed to be grown on the surface of polypropylene beads by producing a biofilm. The observed reduction in COD, BOD and pH indicate the suitability for the application of inverse fluidised bed for waste water treatment for any industry.
