Pennsylvania-based Severn Trent Services has received a contract to provide its Tetra® Denite® denitrification system for the Zhang Gui Zhuang Wastewater Treatment Plant (WWTP) in Tianjin, China.
The project will be the largest deep-bed denitrification installation in the country, and the plant is expected to be a role model for wastewater treatment, sludge processing and water reuse in Tianjin.
The contract was awarded by Anhui Genda Environ, the contractor for Phase I clarifier and filter installation of the new WWTP. The Tetra Denite treatment solution will help the plant meet stringent Class IA effluent discharge standards by simultaneously removing total nitrogen, total phosphorus and total suspended solids.
According to Marwan Nesicolaci, vice president of international sales for Severn Trent Services, “The Zhang Gui Zhuang WWTP plays an important role in the Tianjin Clean Water Project by combining wastewater treatment, sludge processing and water reuse. In fact, the Tetra Denite process has been listed in the Lake Tai WWTP Guide Rules by the Department of Construction of Jiangsu Province.”
