Welcome to SludgeProcessing.com

Welcome to our new website, a technical information source for sludge treatment and the end disposal of waste sludge solids.

So, what is sludge processing? Watch our brief introduction to sludge treatment ...

Sludge is the main waste stream generated from water purification, both water for drinking and wastewater for environmental discharge. It requires processing to reduce its volume (and so the cost of subsequent haulage and disposal), as well as the risk it poses to public health, and more

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

What is anaerobic digestion?

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. Watch our explainer
