GUANGZHOU, China, Dec. 16, 2010 -- Aquatech has been awarded a contract for a Zero Liquid Discharge (ZLD) plant for a coal to chemicals facility in Hailer in Inner Mongolia. The ZLD plant incorporates HERO™ (High Efficiency Reverse Osmosis) and a Thermal Brine Concentrator. The plant will treat 2400 m³/day of wastewater and reuse 92.5% of it, producing 2000 m³/day of process water and 220 m³/day of distilled water for various end-user applications.

The waste streams to be treated are extremely challenging with high COD, BOD, ammonia, silica, and TDS levels that exceed 18,000 ppm. The HERO™ system is used 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 supplying this project on an Engineering & Procurement (EP) basis along with Commissioning service, and is targeting to start the commissioning by mid-2011.

The coal to chemicals plant is owned by Hulunbeier New Gold Chemical Co. Ltd. (NGCC), a Yuntianhua Chemical group company. Yuntianhua Chemical is one of China's largest state-owned enterprises with six major industries and a series of products such as chemical fertilizers, organic chemicals, new glass fiber materials, and phosphate ore mining and dressing.

The plant is located in one of the biggest grasslands in China; the local region is a famous tourist attraction and is also a major coal region attracting major industrial investment. The driving force for ZLD is to strive for a solution that will reinforce the delicate balance between industrial development and environmental conservation.

Tom Tseng, General Manager, Aquatech China, commented, "We are honored that the YTH Group has entrusted Aquatech with such an important project. 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. It is our goal to be the partner of our clients in developing solutions to conserve water and reduce pollution."
