Membrane Sterilization Technology for Biological Liquid Aseptic Filtration
Microbial contamination is one of the key factors causing product deterioration, short shelf life and unqualified sanitary indicators in biological products, beverages and pharmaceutical liquids. Traditional high-temperature sterilization easily damages heat‑sensitive active ingredients, while chemical sterilization causes reagent residue and quality changes. Membrane aseptic filtration realizes efficient removal of bacteria, spores and microorganisms through precise physical screening at room temperature. It achieves sterile liquid standards without thermal damage and chemical pollution, becoming the core aseptic processing technology for modern biological and pharmaceutical industries.
Reverse Osmosis Membrane Technology for Industrial Pure Water Production
Industrial production, pharmaceutical manufacturing, food processing and laboratory testing require stable high-purity process water. Traditional water purification methods including sand filtration, activated carbon and softening treatment can only remove partial suspended solids and impurities, but fail to filter dissolved salts, tiny colloids and microbial contaminants. Reverse osmosis membrane technology uses high-precision pressure-driven physical separation to remove more than 99% of inorganic salts, bacteria, viruses and organic impurities. It stably produces high-standard industrial pure water. With low operating cost and mature modular design, RO membrane has become the core technology for modern industrial pure water and deionized water preparation.
Nanofiltration Membrane for Herbal Extract Decolorization
Crude herbal extract often presents dark color caused by macromolecular pigments, tannin polymers and humus‑like substances. Conventional decolorization relies heavily on activated carbon adsorption, which leads to effective ingredient loss, disposable carbon waste and complicated post‑treatment. Nanofiltration membrane realizes physical decolorization by molecular weight cut‑off difference. It intercepts most high‑molecular‑weight pigments while retaining majority of target active components. This article discusses the mechanism of nanofiltration decolorization, compares with activated carbon process, analyzes influencing factors such as temperature, pH and transmembrane pressure, and states application value for herbal and plant extract factories.
