As professional manufacturers of ultrafiltration water purification equipment, we adopt modified pollution-resistant PVDF hollow fiber and tubular ultrafiltration membrane as the core filter medium, which adapts to complex raw water with fluctuating turbidity, salinity and impurity concentration in different industrial scenarios. Different from traditional quartz sand filtration and activated carbon filtration, ultrafiltration relies on physical micropore interception, featuring stable water output quality, small footprint and high automatic operation degree, which has become essential pretreatment equipment for pure water preparation, brackish water desalination and wastewater reuse.
A complete set of ultrafiltration water purification equipment consists of ultrafiltration membrane module group, anti-corrosion stainless steel frame, raw water delivery pump, automatic backwash valve manifold, online acid-base chemical cleaning dosing device, front security liquid filter and PLC touch screen control cabinet. Raw water is purified through membrane interception to lower the SDI value of inlet water, building safe operating conditions for subsequent deep desalination and fine water treatment equipment. All finished products undergo air tightness test and 72-hour full-load running aging test before delivery to adapt to long-term continuous operation in harsh water environments.
We develop differentiated products to satisfy diversified project demands. Projects with limited installation space adopt integrated skid-mounted Ultrafiltration Integrated Water Purification Equipment to save construction area and installation cost. Chemical, mining and printing dyeing high-pollution wastewater uses wear-resistant Tube Type Ultrafiltration Membrane Equipment to improve anti-fouling ability and extend chemical cleaning intervals. Large-scale central water stations are equipped with intelligent Fully Automatic Ultrafiltration Equipment for Industrial Water to realize unmanned automatic backwashing and timed chemical cleaning. Production tail water can be recycled after treatment by matched Wastewater Treatment Ultrafiltration Equipment. For special water yield, pipeline layout and anti-corrosion requirements from clients, our identity as Manufacturer of Ultrafiltration Membrane Water Purification supports personalized drawing design and exclusive customized production.
Standard frames and pipelines use SUS304 stainless steel; SUS316L material is selected for corrosive brine and acidic wastewater to prevent electrochemical corrosion. The control system supports local touch operation and optional remote cloud monitoring. Our company provides spot standard products, OEM processing, non-standard customization and complete CE certification documents to help overseas customers pass customs clearance smoothly.
Ultrafiltration purification equipment is driven by hydraulic pressure and operates with cross-flow filtration mode. The built-in PLC program automatically switches three cyclic working modes: water production filtration, automatic backwashing and periodic chemical cleaning.
Raw water firstly removes large particulate impurities via the front liquid filter, then flows into the inner cavity of ultrafiltration membranes under pump pressure. With 0.01~0.1μm fixed membrane pore size, water molecules and tiny soluble substances penetrate the membrane wall to form qualified purified water for follow-up processes. Suspended particles, bacteria, algae and organic pollutants are trapped on the membrane surface. High-speed cross-flow raw water continuously scours the membrane surface to slow pollutant cake accumulation and keep stable water flux in long-term operation.
With continuous accumulation of intercepted pollutants, the pressure difference between membrane module inlet and outlet rises gradually. Once reaching the preset threshold, the system switches pipeline valves automatically. Clean produced water flows reversely to flush loose contaminants on membrane surfaces, and sewage is discharged out of the equipment with concentrated water. The whole backwashing process only lasts 3–8 minutes without long-time system shutdown.
Physical backwashing cannot remove stubborn biological slime and organic scale attached inside membrane pores. The supporting dosing system prepares dilute acid and alkali solution for circulating soaking cleaning, which thoroughly recovers the original flux of ultrafiltration membranes and maintains stable purification efficiency.
