Ultrafiltration integrated water purification equipment adopts integral frame skid-mounted integrated design, integrating membrane components, power conveying parts, dosing cleaning system and automatic control system into one whole set of equipment, with modified hydrophilic PVDF hollow fiber membrane as the core filtering medium of the whole device. A complete set of integrated water purification equipment is composed of hollow fiber ultrafiltration membrane module group, SUS304 stainless steel integrated support frame, raw water booster pump, automatic backwash pipeline assembly, online acid-base chemical cleaning device, front security liquid filter and PLC touch screen intelligent control cabinet. As the indispensable primary protection device before reverse osmosis host equipment, this integrated ultrafiltration device can efficiently intercept suspended solids, colloids, algae, bacteria and macromolecular organic pollutants in raw water, stably control the SDI value of produced water below 5, reduce the pollution, scaling risk and chemical cleaning frequency of reverse osmosis membrane elements, and prolong the service life of expensive RO membrane components. All finished integrated ultrafiltration equipment will complete air tightness pressure test and 72-hour full-load continuous operation aging test before leaving the factory to meet the demand of long-term uninterrupted stable operation under various industrial working conditions.
We develop differentiated ultrafiltration products to match different project construction requirements. Users with conventional factory water preparation needs can select the cost-effective benchmark model Hollow Ultrafiltration Equipment for Industrial Water Purification on the basis of integrated equipment. For standardized packaged water treatment projects, the integrated Ultrafiltration UF System for Industrial Water Treatment realizes centralized automatic operation control and greatly reduces the construction difficulty of on-site pipeline installation for engineering parties. For large industrial parks with large water consumption demand, customers can choose the upgraded high-flow High Performance Industrial Ultrafiltration Equipment with expanded membrane area configuration. For printing and dyeing, chemical wastewater advanced treatment and reuse projects, the anti-pollution optimized Ultrafiltration Water Reuse can realize harmless treatment and resource reuse of industrial wastewater. For outdoor open installation and complex harsh environment working conditions, the anti-corrosion upgraded Durable Ultrafiltration Equipment optimizes frame and pipeline materials to improve the overall service cycle of the equipment.
The frame and pipeline of standard integrated ultrafiltration water purification equipment are made of SUS304 stainless steel; SUS316L stainless steel and FRP pipelines are supported for customized production when treating high-salinity and corrosive raw water quality. The built-in PLC automatic control system supports real-time pressure difference monitoring, timing automatic backwashing, equipment fault automatic alarm and remote data viewing functions, which greatly reduces the daily manual operation and management workload of the user side. We provide standard integrated ultrafiltration equipment spot sales, non-standard size layout customization, OEM processing services and complete export certification documents to help overseas customers smoothly pass customs clearance in various countries and regions around the world.
Our ultrafiltration integrated water purification equipment relies on mature pressure-driven cross-flow physical interception principle to complete water purification treatment, and the whole operation cycle is divided into three core working modes: normal water production filtration, automatic backwashing and regular chemical cleaning.
After preliminary filtration through multi-media filter and 5μm precision security filter, raw water is delivered to the inner cavity of hollow fiber membrane filaments under the pressure of the feed pump. The aperture of ultrafiltration membrane is fixed at 0.01~0.1μm. Water molecules and tiny soluble substances penetrate the membrane wall to form qualified clear permeate water, which is transported to the intermediate water tank for subsequent reverse osmosis desalination treatment. Solid particles, colloids and microbial impurities are trapped inside the membrane tube or attached to the membrane surface. The tangential high-speed flow of raw water continuously scours the membrane surface, inhibits the accumulation of pollutant filter cake, and ensures stable water production flux in long-term continuous operation.
With the continuous accumulation of intercepted pollutants, the pressure difference between the inlet and outlet of the membrane module will rise gradually. When the data reaches the preset threshold of the control system, the electric control valve will switch the pipeline automatically. The clean produced water carries out reverse flushing on the ultrafiltration membrane filaments to wash away loose accumulated pollutants, and the concentrated sewage is discharged outwards. The backwashing process takes a short time and will not cause long-term shutdown of the whole water treatment system.
Long-term simple physical backwashing cannot completely remove biological slime, organic attachments and tiny inorganic scale deposited in membrane pores. The supporting dosing system uses diluted acid and alkali liquid for circulating soaking cleaning, thoroughly restores the original permeation flux of the ultrafiltration membrane, and keeps the integrated equipment running efficiently and energy-saving for a long time.
