The ZLD plant will use HERO (High Efficiency Reverse Osmosis) and a Thermal Brine Concentrator to treat 2400 cubic meter /day of wastewater and reuse 92.5% of it, producing 2000 cubic meter/day of process water and 220 cubic meter/day of distilled water for various end-user applications.
The plant, which will treat waste streams with high COD, BOD, ammonia, silica, and TDS levels that exceed 18,000ppm, will utilize the HERO system to concentrate the feed water to a solids level of approximately 8.5% before taking it to the Brine Concentrator and subsequent evaporation pond.
Aquatech will be providing engineering, procurement and commissioning service for this Zero Liquid Discharge project and plans to start the commissioning by mid-2011.
Aquatech China, general manager Tom Tseng said that due to strict pollution control guidelines the reliable maximization of water reuse and ensuring true zero discharge are critical in such an important region of China.
