I.Overview
Ultrafiltration (UF) systems are mainly used in industrial wastewater treatment for suspended solids removal, oil-water separation, heavy metal recovery and wastewater reuse, which can significantly improve water quality and reduce the subsequent treatment load. Its core value in industrial wastewater treatment is: resource recovery (such as heavy metals, protein enrichment and reuse), emission reduction and efficiency (reduce COD, color, to meet the stringent emission standards), process adaptability (flexible combination of RO, electrolysis and other units to deal with complex wastewater).
II.Typical Process Flow
Electroplating Wastewater Treatment (Heavy Metal Recovery):
Electroplating wastewater → adjust pH to 9~10 (metal hydroxide formation) → ultrafiltration (50 kDa) → electrolytic recovery of metals in the concentrated solution → filtrate discharged in accordance with standards
Dyeing wastewater decolorization and reuse:
dyeing wastewater → coagulation (PAC) → ultrafiltration (10 kDa) → activated carbon adsorption → RO → reuse
Petrochemical oil wastewater treatment:
oil-containing wastewater → air flotation emulsion breaking → ultrafiltration (0.02 μm) → effluent oil content <5 mg/L → re-injection or discharge
