Hollow Fiber Ultrafiltration Membrane for Industrial Liquid Clarification and Purification

Hollow fiber ultrafiltration membrane adopts unique capillary fiber structure. Thousands of micro-tube fibers are assembled inside one membrane module, forming ultra-high specific surface area. Compared with tubular membrane and roll-type membrane, hollow fiber module has larger treatment capacity, smaller volume and lower investment cost, which is very suitable for large-volume industrial liquid filtration and water purification projects.

In botanical extraction and pharmaceutical production, the crude material liquid after centrifugal and coarse filtration still contains a large number of tiny suspended particles, micro-colloids and soluble macromolecular impurities. These invisible pollutants will cause long-term membrane fouling, precipitation and turbid finished liquid. Traditional filtration equipment cannot achieve precise interception, while hollow fiber ultrafiltration accurately removes macromolecular impurities through fixed molecular weight cutoff, effectively improving liquid clarity and product stability.

The hollow fiber membrane system adopts internal-pressure or external-pressure cross-flow operation mode. During operation, material liquid flows evenly along the fiber surface, and impurities are continuously scoured to avoid deposition and blockage. Different from rigid inorganic membranes, hollow fiber ultrafiltration supports frequent backwashing and online flushing. Through forward flushing, reverse flushing and CIP chemical cleaning, the membrane flux can be quickly restored, ensuring long-term stable operation of the equipment.

The whole filtration process is pure physical separation at room temperature, without heating, chemical precipitation and organic solvent participation. It effectively protects heat-sensitive active ingredients such as polyphenols, flavonoids and microbial active substances, avoiding yield loss and color darkening caused by traditional processes. After hollow fiber ultrafiltration treatment, the material liquid features high transparency, low impurity content and stable quality, which greatly reduces the load of subsequent nanofiltration concentration and drying processes.

Hollow fiber ultrafiltration has extremely wide industrial adaptability. In plant and traditional Chinese medicine industry, it is used for extract clarification and macromolecular impurity removal. In biological fermentation industry, it removes mycelium and cell debris. In water treatment field, it serves as advanced purification for reclaimed water reuse and raw water filtration. Its modular combination design can freely expand production capacity, meeting small-batch experimental production and large-scale industrial line demands.

The fully automatic PLC control system realizes automatic operation of flushing, circulation and cleaning. The equipment has low energy consumption, simple maintenance and long service life, greatly reducing enterprise operating cost. With excellent comprehensive performance, hollow fiber ultrafiltration membrane has become the basic and indispensable core equipment in modern green membrane separation industry.
