Tubular microfiltration membrane is a robust cross-flow filtration medium with a unique tubular hollow structure, specially developed for industrial liquid purification and solid-liquid separation. Different from flat sheet and hollow fiber membranes, the tubular MF membrane adopts a large-diameter tubular design, allowing high-viscosity liquid, high-suspended solid fluid and oily wastewater to pass through smoothly without easy blockage. With a precise pore size of 0.1μm~1.0μm, it can effectively intercept suspended solids, colloids, bacteria, algae and fine particles in liquids. Widely applicable in harsh industrial filtration scenarios, it is a core filtration component for modern industrial water treatment, material concentration and impurity removal.
The tubular microfiltration membrane adopts a typical cross-flow filtration working mode. The raw liquid flows tangentially along the inner wall of the tubular membrane tube under pressure. Under the action of transmembrane pressure difference, water molecules and small molecular soluble substances penetrate the membrane wall to form permeate clean water, while large particles such as suspended solids, colloids and macromolecular impurities are trapped on the inner surface of the membrane tube and discharged with the circulating concentrate. The high-speed flowing liquid continuously scours the membrane surface, which greatly inhibits the formation of filter cake and membrane fouling. This continuous cross-flow circulation ensures long-term stable filtration flux and avoids frequent shutdown and cleaning caused by surface blockage.
Benefiting from the large-caliber tubular structure and cross-flow operation mode, the membrane tube has a wide flow channel with no dead angle. It can handle raw water with high suspended solids, high turbidity and oily impurities that cannot be filtered by ordinary hollow fiber membranes. The high-speed fluid scours the membrane surface in real time, effectively reducing impurity deposition and membrane fouling, greatly extending the continuous operation cycle of the equipment.
Made of high-quality PVDF or PVC ultrafiltration raw materials with uniform microporous structure and high porosity. The tubular microfiltration membrane maintains high and stable water flux under normal working pressure. Even in long-term continuous industrial operation, the filtration efficiency will not drop sharply, ensuring consistent water outlet quality and improving the overall operating efficiency of the filtration system.
The integral sintered and stretching molding process endows the membrane tube with excellent tensile strength, compression resistance and wear resistance. It can withstand frequent backwashing, chemical cleaning and high-pressure flushing without cracking, peeling or pore deformation. Compared with ordinary filter membranes, it has stronger environmental adaptability and a longer service life, effectively reducing equipment replacement and maintenance costs.
The membrane material features excellent chemical inertness, acid and alkali resistance, and corrosion resistance. It can adapt to a wide pH working range and tolerate conventional chemical cleaning agents such as sodium hypochlorite, dilute acid and dilute alkali. When slight fouling occurs, online backwashing and chemical cleaning can quickly restore membrane flux, with simple operation and low maintenance difficulty.
The tubular membrane has a standardized modular structure, which supports flexible assembly and installation. It can be freely combined into membrane modules and membrane systems according to different water treatment capacities and on-site working conditions. It is highly compatible with various industrial water treatment equipment, skid-mounted systems and circulating filtration devices, meeting the customized filtration needs of different industries.
Widely used in chemical wastewater, printing and dyeing wastewater, electroplating wastewater, mining wastewater and domestic sewage treatment. It effectively removes suspended solids, colloidal pollutants and residual impurities in wastewater, reaching the standard of wastewater reuse and discharge, realizing water resource recycling and reducing enterprise water consumption.
Ideal for oily wastewater treatment in machinery processing, petrochemical, catering and other industries. The special microporous structure can separate oil-water mixtures efficiently, intercept oil slick and emulsified oil particles, solve the problem of difficult purification of oily wastewater, and improve wastewater treatment qualification rate.
Applied to the clarification, impurity removal and sterile filtration of fruit juice, beverage, wine, dairy products and sugar liquid. It removes fine particles, suspended impurities and bacteria in the liquid, improving the clarity, taste and shelf life of products, meeting the food-grade purification standards.
Used for filtration and concentration of biological fermentation liquid, pharmaceutical liquid, chemical reagent and extract. It removes macromolecular impurities, bacteria and particulate contaminants, ensuring the purity and stability of industrial and pharmaceutical liquids.
Suitable for circulating water purification in industrial aquaculture farms. It filters residual bait, fish excrement and suspended impurities in water, improves water transparency and water quality, creates a stable breeding water environment, and reduces the incidence of aquaculture diseases.
