Ultrafiltration vs Ceramic Membrane: How to Choose for Plant‑based Extract Filtration
When clarifying plant‑based extracts, manufacturers often struggle to decide between polymeric ultrafiltration and ceramic membranes. This article compares their investment cost, chemical resistance, service life and operating limits. It offers practical selection principles based on feed liquid solids, viscosity, pH‑temperature conditions and project budget. Buyers should not only focus on upfront price, but also evaluate long‑term running expenses. Pilot tests with real feed material are suggested to confirm actual flux and product recovery. Even high‑performance ceramic membranes require proper pretreatment to avoid severe fouling.
Ultrafiltration Membrane Technology for Fermentation Broth Clarification & Fine Purification
Industrial fermentation broth contains complex mixed components including microbial cell debris, residual proteins, colloidal polymers, suspended solids and metabolic impurities after fermentation completion. Traditional clarification methods such as plate-frame filtration, vacuum filtration and centrifugal separation can only remove large particulate impurities, while tiny soluble proteins and biological colloids remain in the liquid, causing turbidity, poor stability and low product purity. In addition, traditional high-temperature concentration easily damages heat-sensitive bioactive substances and leads to low product yield. Cross-flow ultrafiltration membrane technology realizes low-temperature physical purification and precise impurity removal. It intercepts macromolecular invalid impurities and retains target active metabolites, effectively improving liquid clarity, product purity and batch stability. As an efficient and environmentally friendly refining method, ultrafiltration
# Ultrafiltration Membrane Technology for Fruit Juice Clarification and Impurity Removal
Freshly squeezed fruit juice contains a variety of unstable substances such as pectin, soluble protein, fine pulp fibers and colloidal impurities after crushing and juicing. These micro impurities are the main causes of juice turbidity, post-precipitation, layering and poor shelf stability. Traditional clarification methods including diatomaceous earth filtration, plate-and-frame filtration and centrifugal separation can only remove large suspended particles, but fail to completely eliminate macromolecular colloids. High-temperature sterilization and thermal concentration will destroy natural flavor, vitamins and antioxidant nutrients, seriously restricting the production of high-quality pure fruit juice and concentrated juice products. Cross-flow ultrafiltration membrane technology adopts low-temperature physical screening to realize high-precision clarification of fruit juice. It effectively intercepts invalid macromolecular impurities while retaining small-molecule flavor substances
