Asker, 10 December 2014
Beijing Drainage Construction Company has awarded Cambi a second contract for the Cambi Thermal Hydrolysis Process (CambiTHP™). The Xiaohongmen Wastewater Treatment Plant (WWTP) contract 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 achieving 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 used to treat primary sludge only, with the secondary sludge treated by lime stabilization. The full sludge amount will be treated in CambiTHP, stabilised in the existing digesters, with the final dewatered cake used for land application. The surplus biogas produced will be used in the digestion project for heat and green electricity 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 converting biodegradable material to renewable energy and valuable bio-fertilizer resources, based on its patented thermal hydrolysis process (CambiTHP™).
