This case study introduces the Tarim Ethylene Ethane Project of Dushanzi Petrochemical. The treatment of ethylene waste alkali liquid used the high-efficiency dissolved air flotation produced by our factory as a pretreatment to remove the oil substances entrained in the waste alkali liquid, and good results were achieved.
This case study introduces how Environmental Protection Technology City Industrial Wastewater Treatment Plant Project uses our factory's high-efficiency dissolved air flotation to treat oily wastewater, such as machining and cutting fluids. After treatment, the effluent quality was significantly improved, the effluent indexes of animal and vegetable oils and petroleum reached about 1 mg/L, and the total phosphorus removal rate was over 98%.
