A complete set of ultrafiltration water treatment equipment consists of hollow fiber membrane components, SUS304 stainless steel frame, raw water pump, backwash pump, automatic solenoid valve group, acid-base dosing cleaning tank, front liquid filter and PLC intelligent control cabinet. SUS316 stainless steel is optional for slightly corrosive wastewater environments to prevent pipeline corrosion and leakage. All finished equipment will pass hydraulic pressure test and 72 hours continuous aging test before delivery to eliminate hidden troubles such as program errors and pipeline leakage. We support in-stock delivery, OEM processing, drawing customization and CE certification provision to help overseas customers smoothly complete customs clearance and project acceptance work.
The whole equipment takes liquid pressure as driving force to implement cross-flow ultrafiltration separation, and the PLC program automatically switches three operating modes: water production, automatic backwashing and chemical deep cleaning.
Raw water first passes through the front liquid filter to intercept silt, fiber and large impurities, then is pumped into the ultrafiltration membrane shell. Under transmembrane pressure, water molecules and tiny soluble substances penetrate the membrane wall to form clean produced water for subsequent deep purification or factory reuse. Contaminants such as colloids and microorganisms are intercepted on the membrane surface. The high-speed flowing raw water continuously scours the membrane surface to reduce pollutant deposition and stabilize the system water yield.
With the accumulation of dirt on the membrane surface, the inlet and outlet pressure difference of membrane modules gradually rises. When reaching the set threshold, the system automatically switches valves to use clean produced water for reverse flushing, discharging loose dirt out of the equipment through concentrated water. The whole backwashing process lasts only 3–8 minutes without long-term shutdown of the water supply system.
Physical backwashing cannot eliminate tightly adsorbed organic dirt and biological slime on the membrane surface. The supporting dosing system uses diluted acid and alkali liquid for circulating soaking cleaning to restore the original flux of ultrafiltration membranes and ensure long-term efficient operation of the equipment.
