Pre-treatment using Hydrodynamic Cavitation can be effectively utilized for enhancing the biodegradability of BDWW along with reduction of COD and increase the yield of methane production from B-DWW. Experimental analysis the effect of pre-treatment of Hydrodynamic Cavitation on B-DWW at various contact time from 50-150 min, at different pressure 5-13 bars, with different dilutions 25-50 % for % COD reduction, for increase in B.I. for increase the yield of methane gas from biomethanated waste water (B-DWW). Experiment shows the effect of pressure, contact time and dilution on % COD reduction, B.I. and % yield of methane gas by BMP. Experimental analysis shows that with pre-treatment of H.C. of B-DWW (Biomass) shows the increase the % Yield of methane production. That also effect on the % COD reduction and B.I. of B-DWW favors positive results. Pre-treatment of H.C. decrease the particle size, increase pumpability, increase B.I., reduce COD and % yield of Methane gas from B-DWW. The Optimum parameter for H.C. pre-treatment pressure 5 bar, Contact Time 50 min without dilution. Energy balance prove that pre-treatment of B-DWW by using H.C. process is cost beneficial. Hence by experimental analysis Pre-treatment of biomass (B-DWW) are economical and physical treatment process. HC process is increase % yield of Methane as well as cost saving treatment process and also less time consumed. The biodegradability index increases with increase in the dilution of B-DWW and also increases with increase in the pressure of cavitation process. It’s clear that the % COD reduction increase with increase in the dilution of B-DWW. The % reduction COD reduction also increase with increase in time of cavitation process. As value of % COD reduction increase also increase of % Yield of Methane. As per experimental analysis it’s clear that pre-treatment of biomass (B-DWW) can increase the yield of methane gas up to 14 % as above conditions. These values can be change by changing the conditions.
