For Immediate Release
Beijing Drainage Construction Company has awarded Cambi a second contract for the Cambi Thermal Hydrolysis Process (CambiTHP™). The contract at Xiaohongmen Wastewater Treatment Plant (WWTP) follows the recent contract for Gaobeidian WWTP, Beijing’s largest. Xiaoghongmen is Beijing’s second largest wastewater treatment plant, and is owned and operated by the Beijing Drainage Group. The plant serves a population of two million residents.
The CambiTHP™ technology will help Beijing and China on their way to achieve a highly efficient and robust sludge treatment with huge environmental and economic benefits.
Beijing Drainage Group will use CambiTHP™ to upgrade the Xiaohongmen WWTP’s five large egg-shaped digesters to advanced sludge treatment. The digesters are currently used to treat primary sludge only, with the secondary sludge treated by lime stabilization. Now the full sludge amount will be treated in CambiTHP™ with subsequent advanced digestion in the existing digesters, and the final dewatered cake will be used for land application. The surplus biogas produced will be used in the digestion project for heat and green electricity for use in the WWTP plant.
Beijing Drainage Construction Company, Ltd, is a leading provider of process turn-key solutions, design, and engineering services for wastewater treatment plants in China.
Cambi is a leading provider of technologies for conversion of biodegradable material to renewable energy and valuable bio-fertilizer resources, based on its patented thermal hydrolysis process (CambiTHP™).
