As a professional ultrafiltration equipment supplier, we take membrane physical separation technology as the core to remove colloids, suspended solids, bacteria and macromolecular organic pollutants from raw water. Ultrafiltration devices are mostly installed in the pretreatment section before reverse osmosis equipment, which greatly reduces the pollutant load of high-precision RO membranes and protects expensive reverse osmosis components from contamination damage. We have developed a full range of ultrafiltration products covering integrated systems, conventional membrane equipment and quantitative customized equipment to satisfy different water volume, water quality and site layout requirements.
If you need complete ultrafiltration and reverse osmosis combined water treatment production lines, select Ultrafiltration Equipment Reverse Osmosis Combined Water Treatment Device; for personalized project overall design demands, get custom service via Ultrafiltration Equipment Company Providing Custom Water Treatment; daily factory general water purification adopts mature stable High Efficient Hollow Fiber Ultrafiltration Equipment for Water Treatment; industrial circulating water purification matches Ultrafiltration Organic Membrane Equipment for Industrial Water; large factory water upgrading projects adopt assembled frame type Ultrafiltration Equipment System for Full-Scale Industrial Water; users with fixed water consumption can choose fixed specification Professional 15 Ton Ultrafiltration Equipment for Industrial Water.
A complete set of ultrafiltration equipment consists of hollow fiber membrane modules, SUS304 stainless steel support frame, raw water supply pump, backwash pump, automatic valve group, acid-base dosing cleaning tank, front-end security liquid filter and PLC intelligent control cabinet. SUS316 stainless steel is optional for slightly corrosive wastewater working conditions to prevent pipeline rusting and medium leakage. All finished equipment must pass hydraulic pressure tightness test and 72-hour uninterrupted full-load aging test before delivery to eliminate hidden dangers such as program errors and pipeline leakage on site. Our company supports spot delivery, OEM processing, drawing customization and formal CE certification provision, assisting overseas customers in smoothly finishing customs clearance and project acceptance procedures.
Our ultrafiltration equipment uses hydraulic pressure as the driving force to realize cross-flow membrane filtration separation. The built-in PLC program automatically switches three operation modes: normal water production, automatic backwashing and periodic chemical deep cleaning.
Original water firstly flows through the front liquid filter to block large silt, plastic fiber and particulate impurities, then is transported into the ultrafiltration membrane shell by the raw water pump. Driven by transmembrane pressure difference, water molecules and tiny soluble substances pass through the membrane wall to form clean permeate water for subsequent advanced desalination or factory production reuse. Pollutants including colloids, microorganisms and sludge are intercepted on the outer surface of hollow fiber membranes. High-speed raw water continuously scours the membrane surface to slow down pollutant accumulation and stabilize the overall water production volume of the system.
As dirt accumulates gradually on the membrane surface, the pressure difference between the inlet and outlet of membrane modules will keep rising. When the value hits the preset alarm threshold, the system will automatically switch the valve group and use clean produced water for reverse flushing, discharging loose pollutants out of the equipment with concentrated wastewater. The whole backwashing process only lasts 3–8 minutes and will not cause long-time shutdown of the enterprise water supply system.
Conventional physical backwashing cannot remove tightly attached organic fouling and biological slime on the membrane surface. The matched dosing system uses diluted acid and alkaline liquid for circulating soaking cleaning, restoring the original flux performance of ultrafiltration membranes and guaranteeing long-term high-efficiency stable operation of the whole set of equipment.
