Inner Mongolia Urat Jiyuan WTP Retrofitting Project

Urat Jieyuan WTP originally used Carrousel 2000 oxidation ditch with total scale of 10,000 m3/d, the effluent implemented I-B standard. In 2013, to solve the problems that the effluent COD and ammonia nitrogen exceeded standard in winter, the trans for mation in low-temperature is carried out. The effluent implements I-A standard.

Zhejiang Chung Fu STP Retrofitting Project

Chongfu STP originally used SBR process with a total scale of 30,000 m3/d, facing difficulties consist of expanding the scale to 60,000m3/d,high content of refractory organic matter, large proportion of printing and dyeing, tannery wastewater, strong water quality impact , and shark fluctuation. The effluent need to implement I-A standard in this retrofitting.
