Washington DC calls for Cambi

摘要

Cambi is to build the largest Cambi Thermal Hydrolysis Process plant to date at the District of Columbia Sewer & Water Authority's (DC Water) Blue Plains Advanced Wastewater Treatment Plant in Washington DC. The process will produce biogas and high quality Class A biosolids fertilizer product, all to be built over a minimum area, saving on both investment and operational costs compared to conventional digestion. The biogas will produce green electricity for the plant; reducing its carbon footprint significantly. The contract forms part of DC Water's US$400M biosolids management programme, a joint venture between CDM and PC Construction. This design-build contract includes thickening, pre-dewatering, four trains of the Cambi thermal hydrolysis process, and four digesters. In addition, a 14 MW biogas CHP powerplant contract is soon to be awarded, as well as a post dewatering facility contract.
