1. Product Introduction of Supplied Ultrafiltration Equipment
As a reliable manufacturer that can stably supply ultrafiltration equipment worldwide, we take modified PVDF hollow fiber membrane as the core filter medium of all UF products. The complete set of standard ultrafiltration equipment consists of membrane module bank, stainless steel support frame, raw water delivery pump, automatic backwashing pipeline assembly, acid-base online chemical cleaning device, front security filter and PLC intelligent control cabinet. As the most important pretreatment protection device before reverse osmosis equipment, ultrafiltration equipment can effectively intercept suspended solids, colloids, algae, bacteria and macromolecular organic matter in water, control RO feed water SDI below 5, slow down RO membrane pollution and scaling, and reduce the chemical cleaning frequency of expensive reverse osmosis components. All finished ultrafiltration equipment will pass air tightness test and 72-hour full-load continuous operation aging test before delivery to ensure stable long-term operation under 24-hour industrial working conditions.
We supply differentiated ultrafiltration products for different customer demands and working conditions. For conventional factory pure water preparation projects, the cost-effective Hollow Ultrafiltration Equipment for Industrial Water Purification is our mainstream spot supply product, with short delivery cycle and stable operation effect. For medium-sized centralized water stations and packaged water treatment projects, the integrated Ultrafiltration UF System for Industrial Water Treatment adopts centralized automatic control design, which simplifies on-site installation and debugging work for engineering customers. For large industrial parks and large-scale tons-level water production workshops, the upgraded High Performance Industrial Ultrafiltration Equipment uses parallel layout of multiple membrane components to meet high continuous water output demand. For printing and dyeing, chemical industry wastewater advanced treatment and reuse projects, the optimized anti-fouling Ultrafiltration Water Reuse can cope with high organic pollution water quality and realize waste water resource utilization. For outdoor open installation, severe temperature difference and unattended running conditions, the anti-corrosion Durable Ultrafiltration Equipment optimizes frame and pipeline materials to extend the overall service life of equipment.
The standard frame and pipeline material of all supplied ultrafiltration equipment is SUS304 stainless steel; SUS316L stainless steel and FRP materials are supported for customized production under high salinity and corrosive water quality. The built-in PLC system realizes real-time differential pressure monitoring, automatic timing backwashing, fault pressure alarm and remote data viewing functions, greatly reducing daily manual management pressure. We support bulk wholesale supply, single unit customized processing, OEM & ODM services for global buyers, with complete product qualification documents and export certification materials to smoothly pass customs clearance in various countries and regions.
2. Working Principle of Supplied Ultrafiltration Equipment
All the ultrafiltration equipment we supply adopts mature cross-flow pressure-driven physical screening principle to complete impurity separation, and the whole operation cycle is divided into three core working modes: normal water production filtration, automatic backwashing and periodic chemical cleaning.
2.1 Normal Filtration & Water Production
After being preliminarily filtered by multimedia filter and 5μm security filter, raw water is pressed into the inner cavity of hollow fiber membranes by the feed pump. The fixed aperture of ultrafiltration membrane is controlled at 0.01~0.1μm. Water molecules and tiny soluble substances pass through the membrane wall to form qualified permeate water for subsequent reverse osmosis desalination treatment. Solid particles, colloids and microorganisms are trapped inside the membrane tube or on the membrane surface. The tangential high-speed flow of raw water continuously scours the membrane surface, inhibits the accumulation of pollutant filter cake and maintains stable membrane flux during long-term operation.
2.2 Automatic Backwashing
With the accumulation of intercepted dirt, the pressure difference between the inlet and outlet of membrane modules rises gradually. When the numerical value reaches the preset threshold of the control system, the valve will switch automatically. Clean produced water reversely washes the membrane filaments to flush off loose pollutants, and concentrated sewage is discharged outward. The backwashing process takes only a short time and will not cause long-term shutdown of the whole water treatment system.
2.3 Periodic Chemical Cleaning
Long-term physical backwashing cannot thoroughly remove biological slime, organic attachments and slight inorganic scale deposited in membrane pores. The matched dosing system uses acid and alkali liquid for circulating soaking cleaning to thoroughly recover the original flux of ultrafiltration membranes and keep the equipment running efficiently and energy-saving for a long time.
