BEIJING, China – The first of Norwegian firm Cambi’s five thermal hydrolysis (THP) projects across China has been opened in Beijing.
The XiaoHongMen wastewater treatment plant treats 600,000 m3/day in the Chaoyang District and will use the THP technology as part of a biogas development.
Sewage sludge is pre-treated at high temperature and pressure (approx. 160℃), before it undergoes anaerobic digestion and becomes biogas and Class A biosolids, which are being used for reforestation projects in Beijing.
This is development is part of a string of projects Cambi secured across China at the end of 2014.
