Sludge stabilisation

Stabilisation processes as applied to sludge are those which reduce its odour and putrescence (i.e. decay), and level of pathogenic organisms. This is generally achieved either chemically or biologically.

Anaerobic digestion − an introduction

Anaerobic digestion (AD) is the most extensively employed sludge stabilisation process and, as with most sludge and wastewater unit processes, the design and performance of AD depends on the feed characteristics. Professor Simon Judd explains.

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
