Rotary drum thickeners

Rotary drum thickening increases the sludge solids concentration by agitating the solids in a slowly-rotating cylindrical drum with porous walls though which the water (or filtrate) drains. The drum is normally 0.5−1.5 m diameter drum and rotates at speeds between 5 and 20 RPM while the sludge continually passes along its axis.

Co-processing of sewage digestate by hydrothermal carbonisation

Hydrothermal carbonisation (HTC) can be used to co-process anaerobic digestion (AD) digestate and lignocellulosic (or plant-based) feedstocks to improve the the hydrochar product quality. This AD waste co-processing route has been studied at bench scale. Read article
