Ultrafiltration water treatment equipment uses pressure as the driving force and ultrafiltration membrane technology to remove colloids, particles, bacteria, viruses, heat sources and macromolecular organic matter in water, so that the water can be purified. It has excellent effects on deep turbidity reduction, clarification, sterilization, and separation, concentration, classification, and purification of organic macromolecular substances. It has high filtration accuracy, simple operation, energy saving and environmental protection.
