The Microporous Filter System is a fully enclosed, micron-levelsolid-liquid separation microfiltration machine. The complete filtrationsystem consists of five parts: the equipment body, a quick-openingbottom cover, PE/PA/PTFE filter tubes, a regeneration system, and anautomatic control system. It is primarily used for filtering small amountsof activated carbon or trace impurities, fine filtration of brine containingcalcium and magnesium salts in chlor-alkali production, fine filtration ofraw materials in inorganic salt production, high-volume fine filtration ofchemical liquids, and fine filtration of mother liquor, crystallization liquid,and leaching solutions.
Fully automatic and systematic design; the system can achievemicron-level filtration, automatic discharge, automatic regeneration, andautomatic interlocking of liquid level, temperature, flow rate, and pump;
Backwashing effect is superior to similar filters; the filter element isreusable, resulting in low operating costs and long service life;
Used for wet discharge filtration, the filter element is backwashed byinternal and external pressure; the unique design increases reverse flow;
No moving parts in the filter body, resulting in low maintenance costs.Compared with traditional filters, this filter occupies less space, is easy tooperate, allows for CIP in-situ cleaning, and all internal components canbe removed;
Fully enclosed filtration system, ensuring clean production and noenvironmental pollution;
Fluid Entry – Raw fluid enters the system through the inlet.
Filtration – Fluid passes through the microporous membrane.
Particle Retention – Particles, impurities, and suspended solids larger than the membrane pore size are trapped on the surface or within the membrane structure.
Clean Fluid Passage – Only filtered, clean fluid passes through the membrane to the outlet.
Pressure & Flow Maintenance – System maintains stable pressure and consistent flow throughout operation.
Contamination Prevention – Trapped impurities prevent contamination of downstream processes.
Optional Cleaning/Sterilization – Membrane can be cleaned or sterilized for reuse, maintaining performance and extending service life.
The liquid containing impurities enters the filter system through the inlet.
The liquid passes through the microporous membrane, and solid particles and suspended solids are retained on the membrane surface or within the pores.
The retained solid impurities are periodically cleaned or backwashed to ensure membrane flux and service life.
The liquid is evenly distributed over the surface of the microporous membrane to prevent local erosion or blockage.
The clean liquid flows along the inner side of the membrane and is collected at the outlet.
The system can operate continuously to achieve stable and high - precision filtration.

A Microporous Filter System is an advanced filtration system that uses membranes or filter media with extremely small pore sizes to remove fine particles, bacteria, and impurities from liquids or gases, achieving high-precision separation.
The system works by forcing fluid through a microporous membrane. Particles larger than the pore size are retained on the surface or within the filter media, while clean fluid passes through as filtrate.
Key advantages include high filtration accuracy, reliable removal of fine particles and microorganisms, stable performance, compatibility with sterile processes, and suitability for high-purity applications.
These systems are widely used in pharmaceuticals, biotechnology, food and beverage, electronics, semiconductor manufacturing, chemical processing, and medical applications where high-purity filtration is required.
Common filter materials include PTFE, PVDF, PES, PP, and stainless steel sintered elements, depending on chemical compatibility, temperature resistance, and filtration requirements.
This duplex system ensures continuous water flow via a twin-barrel design, effectively preventing nozzle and equipment clogging caused by high-impurity mine water in both underground and surface operations.
