Pasteurisation of Sludge
_HRS Digestate Pasteurisation System (DPS) - Agri-Gen UK

Pasteurisation of Sludge

The heating and concentration of waste water streams and sludge is an essential process in many industries, not just water treatment. In particular pasteurisation of sewage sludge and digestate (biosolids) to make them biologically safe for further processing, disposal or use is a key process. Two common issues with some other sludge pasteurisation systems are…

Sewage Treatment
HRS Sewage Treatment

Sewage Treatment

Thermal hydrolysis is a process where the long chain molecules which form cellulose and hemicellulose are broken apart using heat in order to obtain the constituent parts of the molecules. This makes it an economic pre-treatment for biomass being used to produce bioethanol or biogas. Given that cellulosic biomass is plentiful, it has attracted interest…

Bioethanol
HRS Bioethanol Applications

Bioethanol

Bioethanol is the most common biofuel worldwide, based on alcohols produced by the fermentation of sugars contained in corn, wheat, sugar beet, sugar cane, etc. The process also frequently produces a co-product called distiller’s grains, which is a high protein animal feed. HRS Heat Exchangers produce a number of heat exchanger solutions for bioethanol production…
