How Tubular Membrane Technology Purifies Hydrolyzed Bovine Collagen Peptides
Enzymatic hydrolysate of bovine collagen contains residues, grease and salts. Tubular ultrafiltration clarifies the liquid and removes macromolecular impurities, while nanofiltration realizes room-temperature desalination and concentration. The membrane technology protects peptide bioactivity, lowers energy cost and improves the purity of hydrolyzed bovine collagen peptides for food and cosmetic industries.
# Pervaporation Membrane Separation Technology for Solvent Recovery in Plant Extraction
Pervaporation is a novel membrane‑based separation technology driven by vapor partial pressure difference. Different from nanofiltration and ultrafiltration which rely on liquid‑phase sieving, pervaporation membrane realizes component separation through selective dissolution‑diffusion. It is mainly applied for organic‑solvent dehydration and solvent recovery in plant extraction industry. Traditional solvent recovery mostly adopts distillation process, which requires high‑temperature boiling and consumes large amount of steam. Pervaporation membrane completes dehydration under mild temperature conditions, reduces thermal decomposition of target substances and cuts overall energy consumption. It provides an energy‑saving alternative for herbal and botanical extract production.
# Ceramic Membrane Technology for High-Tolerance Industrial Liquid Clarification and Fine Filtration
Traditional organic membrane filtration is limited by poor temperature resistance, weak chemical stability and easy fouling, making it difficult to adapt to high-temperature, high-viscosity and high-impurity industrial crude liquid treatment. Ceramic membrane is a new type of inorganic separation material with high mechanical strength, acid and alkali resistance, high temperature resistance and anti-pollution performance. It can stably remove suspended solids, fine slag, colloidal impurities and macromolecular pollutants in complex material liquids under harsh working conditions. With outstanding advantages of long service life and easy cleaning and regeneration, ceramic membrane technology has become the preferred high-efficiency clarification process for high-difficulty industrial liquid purification.
