Biomass is any organic matter wood, crops, seaweed, animal wastes that can be used as an energy source. Biomass is the oldest source of energy after the sun. Biological organic matter derived from living or recently living organisms is called as biomass . The energy contained or stored in biomass is called as the bioenergy. The hydrodynamic cavitation can be effectively utilized for enhancing the biodegradability of complex wastewater such as B-DWW along with reduced toxicity ( COD / TOC and color). The hydrodynamic cavitation is capable of enhancing the efficiency of reduction of toxicity as well as increase in biogas generation, along with a significantly net higher reduction in COD and color for B-DWW. The effect of hydrodynamic cavitation at different dilution on COD reduction with different contact time of biomethanated waste water (B-DWW). When increase the contact time, pressure and dilution the rate of Color and COD reduction then increase for the B-DWW. Experiment carried out between the 30 – 150 mins time and 25, 50% dilution. The hydrodynamic cavitation at different dilution on biodegradability index variation with different contact time of biomethanated waste water (B-DWW). As increase in contact time, pressure and dilution the biodegradability index increase for the B-DWW. Experiment carried out between the 30 – 150 mins time and 25, 50% dilution.

Pretreatment of biomass, hydrodynamic cavitation, B-DWW Waste Water Treatment.
