Thermal hydrolysis processes

Hydrothermal processes (HTPs) for treating sludge employ elevated temperatures and pressures in wet conditions and in the absence of oxygen. They can be employed for either pre-treating sludge prior to anaerobic digestion (AD) or direct conversion of organic carbon to useful combustible products. Hydrothermal pretreatment for AD employs lower operating temperatures and pressures than the direct conversion processes and do not substantially reduce the organic carbon content.

Biosolids vs sewage sludge

Biosolids are usually considered to be the useful fraction of the sewage sludge. They are generally higher in solids concentration and lower in pathogen content, having gone through a stabilisation process such as chemical dosing, digestion and/or drying.
