Clean TeQ Water is currently commissioning a 12MLD BIONEX™ plant for nitrate removal to reach a concentration of < 1ppm in China.


Clean TeQ Water was recently awarded a contract to design, procure, deliver, and install a BIONEX™ nitrate removal plant at a coal mine in China.  The plant has been designed to treat and remove nitrate from 12,000 m3 /day of coal mine pit water to bring the total nitrogen concentration below 1 ppm to comply with local regulations governing mine water disposal. The plant recently produced the first water, which can be read about here.
