Durable Ultrafiltration Equipment Device for Industrial Water Treatment

Ultrafiltration equipment device is a physical separation water treatment facility widely used for solid-liquid separation, water purification and sewage recovery in global industrial production and municipal environmental protection projects. As a professional manufacturer supplying all kinds of industrial liquid filter solutions with independent research and production capabilities, Xinxiang Lifeierte Filter Corp., Ltd designs and manufactures a full lineup of ultrafiltration devices including high pollutant load Concentrated Ultrafiltration Membrane Equipment, high purification precision Dual Stage Ultrafiltration Equipment, space-saving skid-mounted Compact Small Scale Ultrafiltration Membrane Equipment, and factory pre-assembled integrated Complete Ultrafiltration Equipment to match diverse working conditions across multiple industries. This article comprehensively explains the structural composition, internal filtration mechanism, unified technical specifications, strict factory inspection standards and practical application value of ultrafiltration equipment devices, helping global purchasers select suitable UF devices to stabilize water quality output, cut water treatment operating costs and achieve wastewater resource recycling.

1. Product Introduction of Ultrafiltration Equipment Device

A complete ultrafiltration equipment device takes modified PVDF hollow fiber ultrafiltration membrane as the core filtering component, matched with stainless steel frame support system, raw water boosting pump set, backwash pipeline, chemical dosing cleaning unit, online pressure monitoring gauges and intelligent PLC control cabinet to form a fully automatic closed-loop filtering system. Different from civilian small water treatment products, industrial-grade ultrafiltration equipment device is developed for long-time 24-hour continuous operation, resisting sudden water quality fluctuation impact and maintaining stable large-flow water production capacity, which is the core pretreatment device for pure water making and terminal wastewater treatment in modern factories.

We classify standardized ultrafiltration equipment devices according to different industrial processing demands. For waste liquid concentration, material recovery and high-concentration industrial sewage treatment projects, customers can choose Concentrated Ultrafiltration Membrane Equipment. This device optimizes the layout mode of membrane modules, strengthens the system’s anti-pollution ability and improves the concentration multiple of wastewater treatment. For pharmaceutical purified water, electronic ultrapure water pretreatment and other high-standard water preparation processes that put forward strict requirements on water cleanliness, Dual Stage Ultrafiltration Equipment adopts two-stage graded interception technology to deeply intercept tiny colloids, suspended solids and microorganisms, effectively improving the stability of subsequent water treatment links. For small processing workshops, laboratory water supply and projects with limited equipment placement space, the cost-effective Compact Small Scale Ultrafiltration Membrane Equipment adopts integrated skid-mounted overall layout, featuring easy transportation and plug-and-play installation mode, greatly saving customers’ civil construction and installation investment. For large industrial park centralized water supply, municipal reclaimed water upgrading and factory overall water system renovation projects, Complete Ultrafiltration Equipment finishes pipeline layout, assembly and functional debugging inside the factory before delivery, shortening project construction cycle and reducing the difficulty of field construction management for engineering companies.

All ultrafiltration equipment devices produced by our factory adopt anti-fouling modified PVDF membrane with excellent acid resistance, alkali resistance and oxidation resistance. The standard bracket material is 304 stainless steel, while 316L stainless steel and anti-corrosion plastic pipes can be customized for electroplating, chemical and other corrosive wastewater environments. The independently programmed PLC control system realizes automatic backwashing, timing chemical cleaning and differential pressure pollution early warning, realizing unattended automatic operation of the whole device, adapting to the unmanned management mode of modern industrial workshops.

2. Working Principle of Ultrafiltration Equipment Device

All our ultrafiltration equipment devices adopt mature pressure-driven cross-flow filtration technology, and the system circulates between normal water production filtration and membrane cleaning regeneration during actual operation.

Normal Filtration & Water Production Stage

Raw water is pressurized by the feed pump to a stable working pressure of 1.0–3.6 bar and flows into the inner cavity of the ultrafiltration membrane module. Relying on the physical screening effect of 0.01~0.1μm micropores on the membrane wall, water molecules and small-molecule soluble inorganic substances penetrate the membrane layer smoothly to form qualified produced water for industrial use. Impurities such as suspended solids, colloids, bacteria and macromolecular organic matter are intercepted on the outer surface of hollow fiber membranes. Part of the fluid flows at high speed along the membrane surface to form cross-flow concentrated water, which continuously scours most intercepted pollutants and avoids compact filter cake accumulation and membrane pore blockage.

Membrane Cleaning & Automatic Regeneration Stage

After long-term continuous operation, partial pollutants will deposit on the membrane surface and cause the decline of system water yield. The built-in program of the ultrafiltration equipment device will automatically activate two cleaning modes: regular backwashing uses clean produced water for reverse flushing to peel off loose dirt attached to the membrane surface; periodic CIP chemical cleaning uses special cleaning agents to decompose biological slime and organic fouling, restore the original flux of membrane components, and guarantee long-term stable water production efficiency of the whole device.
