Abstract: 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.
Keywords: MSW; municipal solid waste; rumen fluid; hydrolysis rate; anaerobic digestion; leachate.
