Enhancing the hydrolysis step in anaerobic digestion of municipal solid waste using rumen fluid

Bench scale reactors were operated to optimise the hydrolysis rate of municipal solid waste (MSW) using daily and alternate day addition of 3%, 5% and 10% V/V of rumen fluid. Quantitative and qualitative analysis of leachate were practised daily. Cumulative pollution leaching, i.e. COD, TS, VFA and Amm-N, was comparatively higher with the daily addition of rumen fluid than the alternate addition practised. Finally the results proved that, the addition of rumen fluid at 5% V/V was effective in hydrolysing the MSW.
