Ultrafiltration membrane filtration equipment uses polymer ultrafiltration membrane components as the core filtering medium, relying on micro-scale membrane pore channels to separate impurities in water under pressure driving force. The complete set of equipment is composed of ultrafiltration membrane module group, stainless steel frame assembly, raw water delivery pump, automatic backwashing pipeline, chemical online cleaning unit, front precision security filter and PLC intelligent control cabinet. As the front protective barrier of reverse osmosis equipment, ultrafiltration membrane filtration equipment intercepts suspended solids, colloids, plankton, bacteria and macromolecular organic pollutants in water, effectively controlling RO inlet water SDI value below 5 and effectively delaying membrane fouling and scaling of expensive reverse osmosis elements. All finished equipment will pass air tightness test and 72 hours full-load continuous operation debugging before leaving the factory to adapt to 24-hour uninterrupted industrial production conditions.
We develop multiple series of ultrafiltration membrane filtration equipment to match different working conditions and system collocation demands. For general factory raw water purification projects, the mature Hollow Ultrafiltration Equipment for Industrial Water Purification is the most cost-effective conventional model for supporting RO pretreatment. For medium-sized water stations and integrated water treatment projects, the integrated assembled Ultrafiltration UF System for Industrial Water Treatment realizes centralized automatic control and reduces on-site installation difficulty. For large industrial parks and tons-level large-flow water making workshops, the enhanced High Performance Industrial Ultrafiltration Equipment adopts parallel membrane module layout to meet high-volume continuous water output requirements. For printing and dyeing wastewater, chemical wastewater advanced recovery projects, the targeted Ultrafiltration Water Reuse is optimized for anti-pollution performance to realize wastewater resource recovery. For outdoor harsh environments and long-term unattended operation scenarios, corrosion-resistant Durable Ultrafiltration Equipment improves the anti-aging ability of frame and pipeline materials to extend the whole machine service life.
Standard frames and pipelines of ultrafiltration membrane filtration equipment adopt SUS304 stainless steel material; SUS316L stainless steel and FRP materials are optional customization options for high salinity and corrosive water quality environments. The built-in PLC control system realizes differential pressure automatic monitoring, timing backwashing, abnormal pressure alarm and remote data viewing functions, greatly reducing daily manual maintenance workload. As the original manufacturer without intermediate dealers, we provide customers with process scheme calculation, field installation guidance, long-term spare parts supply and permanent free remote technical training services.
Ultrafiltration membrane filtration equipment adopts cross-flow filtration mode, relying on physical screening effect of fixed membrane pores to complete impurity separation. The whole working cycle is divided into normal filtration water production, automatic backwashing and periodic chemical cleaning three core working links.
After being pretreated by multi-media filter and security filter, raw water is sent into the ultrafiltration membrane shell by the feed pump. The membrane pore size of ultrafiltration membrane is fixed at 0.01~0.1μm. Water molecules and small soluble substances penetrate the membrane layer to form qualified permeate water for subsequent reverse osmosis desalination treatment. Particulate pollutants, colloids and microorganisms are trapped on the surface or inside the membrane pores. The cross-flow water flow continuously scours the membrane surface to slow down the accumulation of filter cake and keep stable membrane flux.
With the accumulation of intercepted dirt, the pressure difference between the inlet and outlet of the membrane module gradually rises. When the pressure difference reaches the system set value, the control system automatically switches the pipeline valve. Clean produced water reversely washes the ultrafiltration membrane surface to wash away loose pollutants, and the wastewater is discharged outwards. The backwashing process is short and will not affect the continuous operation of the whole water treatment system.
Long-term physical backwashing cannot thoroughly remove biological slime, organic dirt and slight inorganic scale attached to the membrane pores. The supporting acid and alkali dosing system performs circulating soaking cleaning to thoroughly restore the original flux of the ultrafiltration membrane and maintain the high-efficiency and low-energy operating state of the membrane filtration equipment for a long time.
