Refractory Wastewater Treatment

The PTMEG project was invested by Lutianhua Chemical Company. The designed capacity of wastewater treatment plant is 2880m³/d. The sources of 1200m³/d high-concentration wastewater include Methanol unit, Hydrogen unit, Methane-to-Acetylene unit, Formaldehyde unit, and BDO unit. Others: 1680m³/d wastewater comes from plant sewage, initial storm water in contaminated areas, emergency wastewater, and fire protection wastewater. These types of wastewater contain chromaticity and odors, with COD reaches up to 8200mg/L.

For this EPC project McWong utilized MBR membrane technology. The design capacity of the equipment is 120m³/h. Construction started in March 2011, and the sludge cultivation was completed along with the start of full operation of the entire facility in June 2012. Test results showed that effluent met all the requirements of the national wastewater discharge standards. This major project was heralded by influential industry media such as China Chemical Industry News, and China Chemical Industry Network.
