Large Scale Ultrafiltration Equipment for Industrial Water Projects
Large scale ultrafiltration equipment refers to centralized, skid-mounted ultrafiltration systems designed for high-flow industrial water treatment projects, widely deployed in municipal water plants, large manufacturing parks and industrial wastewater zero-discharge projects with high water volume demand. Our factory supplies a full spectrum of industrial liquid filter products covering large-scale ultrafiltration units together with standard filtration devices, including basic Hollow Ultrafiltration Equipment, modular integrated Ultrafiltration UF System, anti-fouling High Performance Industrial Ultrafiltration Equipment, water recovery-focused Ultrafiltration Water Reuse Equipment and long-service-life Durable Ultrafiltration Equipment Device, forming a complete product portfolio for small, medium and large water treatment projects. This paper comprehensively analyzes the structural composition, cross-flow filtration operating principle, unified technical specifications, strict whole-process quality management standards and mainstream industrial application scenarios of large scale ultrafiltration equipment. Global engineering contractors, water treatment system integrators and large factory procurement departments can fully recognize the operational stability, mass delivery capability and comprehensive after-sales support of our large-scale ultrafiltration products, so as to deploy matched large-volume membrane filtration solutions to stabilize long-term water quality and cut overall project operation costs.
Different from small skid-mounted ultrafiltration machines for workshop single-point water use, large scale ultrafiltration equipment adopts modular array layout, arranging dozens or hundreds of hollow fiber membrane components on heavy-duty steel frames, matched with multi-group large-flow feed pumps, centralized backwashing pipelines, centralized chemical cleaning dosing stations, multi-stage security filtration systems and centralized PLC distributed control system to realize automatic unmanned operation of tons-level water treatment volume. Every finished large-scale ultrafiltration equipment will pass hydraulic tightness test, continuous 72-hour full-load operation test and linkage program debugging before delivery to ensure stable long-term operation in harsh industrial environments.
We match large-scale ultrafiltration main equipment with diversified auxiliary filtration products to satisfy differentiated project construction needs. For small water volume supporting sections in large projects, customers can select economical Hollow Ultrafiltration Equipment for partial water purification treatment. For overall station construction of large water plants, the combined Ultrafiltration UF System realizes unified pipeline layout, centralized monitoring and synchronous operation of multiple membrane groups. For wastewater with high suspended matter and organic pollutants in chemical, printing and dyeing industries, enhanced High Performance Industrial Ultrafiltration Equipment effectively slows down membrane pollution speed and reduces cleaning frequency. In enterprise water saving and zero-discharge renovation projects, optimized Ultrafiltration Water Reuse Equipment raises the system water recovery rate and improves the utilization rate of industrial water resources. For continuous 24-hour uninterrupted operation scenarios, wear-resistant Durable Ultrafiltration Equipment Device is combined with large-scale main units to extend the whole system service cycle.
The frame, main pipeline and valve body of large scale ultrafiltration equipment are made of SUS304 stainless steel as standard configuration; SUS316 stainless steel is customized for corrosive wastewater working conditions. The central control system supports remote data viewing, differential pressure automatic alarm, automatic backwash trigger and timing chemical cleaning functions, greatly reducing on-site manual management work. As the direct manufacturing manufacturer without intermediate links, we provide large-scale ultrafiltration scheme calculation, on-site installation guidance, long-term membrane spare parts supply and full-cycle technical training services for global customers.
Large scale ultrafiltration equipment follows the cross-flow filtration theory, takes pressure difference as driving force, and relies on the microporous structure of PVDF hollow fiber membranes to classify and intercept impurities in water. The whole working cycle is divided into three core operating modes: normal water production filtration, centralized automatic backwashing, periodic chemical circulating cleaning.
Raw water is boosted by multiple feed pumps and evenly delivered into each hollow fiber membrane module in the array. The membrane aperture is controlled stably at 0.01~0.1μm. Water molecules and tiny soluble ions pass through the membrane wall to form qualified produced water for subsequent reverse osmosis treatment or direct reuse. Suspended solids, colloids, bacteria, algae and macromolecular organic pollutants are trapped inside the hollow fiber filaments. The high-speed cross flow of raw water scours the inner wall of the membrane continuously, inhibiting the accumulation of pollutant cake layers and keeping stable membrane flux under long-term high-load operation.
With the accumulation of intercepted pollutants, the pressure difference of each membrane group rises gradually. When the system detects the preset pressure threshold, the PLC system opens the unified backwashing pipeline at the same time. Clean produced water performs reverse flushing on all membrane modules in batches to wash away surface pollutants and discharge concentrated sewage out of the equipment through the sewage pipeline. Batch backwashing avoids the overall shutdown of the large system and guarantees continuous water supply.
Long-time high-load operation will lead to organic dirt, biological slime and inorganic scale inside membrane pores, which cannot be completely removed by physical backwashing. The centralized dosing station inputs acid and alkali cleaning agents for circulating soaking cleaning to eliminate stubborn pollution thoroughly, restore the initial flux of hollow fiber membranes and guarantee the long-term efficient operation of large scale ultrafiltration equipment.
