Which Membrane Is Suitable for High Solid Content Feed Liquid?
High solid content feed liquid often triggers equipment clogging and frequent fouling during industrial filtration. Picking the wrong filtration module brings low flux, short service life and rising operational cost. This article compares tubular and spiral wound options, explaining why tubular ultrafiltration is preferred for high-solids materials. Its large open flow channel creates strong cross-flow scouring to reduce cake layer buildup. It supports backwash and CIP cleaning, widely used for gelatin, collagen, fermentation broth and juice processing. Proper pretreatment and TMP setup are required for stable running.

Spiral Wound Nanofiltration Membrane for Industrial Fine Purification and Concentration
Spiral wound nanofiltration membrane is a mainstream compact membrane element designed for industrial fine separation, featuring high filling density, stable interception precision and low energy consumption. It is specially applied in deep desalination, selective decolorization, impurity removal and low-temperature concentration of plant extracts, fermentation liquids and natural product solutions. Different from hollow fiber and tubular membranes, spiral wound nanofiltration realizes high-efficiency graded separation of small-molecule impurities and active ingredients through unique spiral flow channel design. With stable separation performance and easy industrial integration, it has become the preferred core equipment for high-precision refining of modern natural biological products.
Hollow Fiber Ultrafiltration Membrane for Industrial Liquid Clarification and Purification
Hollow fiber ultrafiltration membrane is a mainstream precision separation element with self-supporting microporous structure, featuring high packing density, large flux and low operating pressure. It is widely used for fine clarification, impurity removal and purification of plant extracts, traditional Chinese medicine liquid, fermentation broth and process water. Different from tubular and spiral membrane elements, hollow fiber membranes provide ultra-large filtration area in compact space, realizing high-efficiency physical filtration. With flexible backwashing and anti-fouling performance, hollow fiber ultrafiltration has become the most widely used core membrane equipment for industrial primary refining and water treatment.
