Industrial ultrafiltration equipment has become indispensable core water treatment facilities for modern factory production, sewage recycling and pure water preparation across global manufacturing industries. As a mature industrial liquid filter solution provider with independent R&D and manufacturing capacity, Xinxiang Lifeierte Filter Corp., Ltd develops and manufactures diversified industrial UF products including high-load Concentrated Ultrafiltration Membrane Equipment, high-precision Dual Stage Ultrafiltration Equipment, space-saving Compact Small Scale Ultrafiltration Membrane Equipment, and full assembled Complete Ultrafiltration Equipment to satisfy diverse working conditions of chemical, food, pharmacy, municipal and electroplating industries. This paper systematically explains the product composition, internal filtration mechanism, unified technical indicators, strict factory inspection standards and multi-scenario industrial application values of industrial ultrafiltration equipment, helping industrial purchasers select matched ultrafiltration devices to stabilize effluent quality, lower water treatment operating costs and realize clean production goals for enterprises.

1. Product Introduction of Industrial Ultrafiltration Equipment

Our industrial ultrafiltration equipment takes modified PVDF hollow fiber ultrafiltration membrane as the core filtering medium, matched with stainless steel frame, feed pump unit, backwash pipeline system, dosing cleaning system, pressure monitoring instruments and intelligent PLC control cabinet to form a fully automatic closed industrial filtering system. Different from household small water purifiers, industrial ultrafiltration equipment is designed for long-term 24-hour continuous operation, strong impact resistance to fluctuating water quality and large-flow stable water output, specially oriented to various industrial production water treatment demands.

According to different industrial usage scenarios and processing standards, our company classifies standardized industrial ultrafiltration products. For industrial wastewater concentration separation, waste liquid recycling and high-concentration sewage treatment projects, customers can choose Concentrated Ultrafiltration Membrane Equipment. This equipment optimizes the membrane module arrangement structure, improves the pollutant carrying capacity of the system and effectively promotes the wastewater concentration ratio. For pharmaceutical purified water, electronic industry ultrapure water pretreatment and other high-standard water making processes, Dual Stage Ultrafiltration Equipment is adopted with two-stage graded interception technology to deeply remove tiny colloids, suspended matters and microorganisms, greatly improving the safety and stability of subsequent water treatment processes. For small processing plants, workshop auxiliary water supply and projects with limited equipment placement space, the hot-selling Compact Small Scale Ultrafiltration Membrane Equipment adopts integrated skid-mounted design with small occupied area, convenient transportation and on-site plug-and-play installation, which greatly reduces the civil construction and installation cost for enterprises. For large industrial parks, municipal reclaimed water stations and overall factory water system upgrading projects, Complete Ultrafiltration Equipment is fully assembled, piped and debugged in the factory before delivery, shortening the project construction period and reducing the difficulty of on-site construction management.

All industrial ultrafiltration equipment produced by our factory uses anti-fouling modified PVDF membrane with excellent acid resistance, alkali resistance and oxidation resistance. The standard frame is made of 304 stainless steel, and 316L stainless steel or anti-corrosion plastic materials can be customized for corrosive wastewater environments such as electroplating and chemical industry. The intelligent control system independently compiled by our technical team realizes automatic backwashing, timing chemical cleaning and differential pressure pollution early warning without manual real-time duty, fully adapting to the unattended operation mode of modern industrial workshops.

2. Working Principle of Industrial Ultrafiltration Equipment

All series of industrial ultrafiltration equipment apply pressure-driven cross-flow filtration technology, and the system circulates between normal water production filtration and membrane cleaning regeneration states during operation.

Normal Filtration & Water Production Stage

The raw industrial water is boosted by the feed pump to a stable operating pressure of 1.0–3.6 bar and flows into the inner cavity of the ultrafiltration membrane component. With the physical screening effect of 0.01~0.1μm micropores on the membrane wall, water molecules and small molecular soluble inorganic salts penetrate the membrane smoothly to form qualified produced water for industrial production. Suspended solids, colloids, bacteria, organic macromolecules and other harmful impurities are intercepted on the outer surface of hollow fiber membranes. Part of the water flows at a high speed along the membrane surface to form cross-flow concentrated water, which continuously washes away most intercepted pollutants and prevents compact filter cake from accumulating on the membrane surface to block the membrane pores.

Membrane Cleaning & Automatic Regeneration Stage

After long-term continuous industrial operation, partial pollutants will deposit on the membrane surface to cause system water yield decline. The built-in program of industrial ultrafiltration equipment will automatically start 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 matched cleaning agents to decompose biological slime and organic fouling, restore the original flux of membrane components and ensure the long-term stable water production efficiency of industrial equipment.
