Centrifuges

Centrifugal dewatering increases the sludge concentration by encouraging the particles to migrate to the walls of a rapidly rotating cylindrical vessel under the influence of a centrifugal force. Relatively high rotation speeds are employed to produce a cake product having a substantially higher solids concentration than the thickened sludge product produced by centrifugal thickening.

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
