Abstract:

The pilot study of the treatment of ultrasonic cleaning wastewater by the ultrafiltration-nanofiltration combined process has been carried through. The results show that the system could effectively remove various pollutants. When the effluent turbidity≤0.1 NTU，COD_Mn≤1.5 mg/L，conductivity≤55 μS/cm，and phosphate ≤ 0.17 mg/L，the effluent water quality meets the requirements of industrial water. During the two-month running，the double-membrane system runs steadily.
