Process Membranes

Typical particle size suitable to MF membranes ranges from 0.1 to 0.45 μm.

These membranes can prevent particles such as suspended solids, bacteria, and macromolecular colloids–while allowing clarified feed with dissolved solutes, inorganic salts, and other macromolecules.

Characterized by their molecular weight cut-off (MWCO) between 1,000 – 200,000 Dalton, and higher cut-offs spill into the MF range.

• Clarification of fermentation broth in the pharmaceutical and biotechnology industries.
• Concentration of skimmed milk protein, whey protein, gelatin, and other natural extracts, protein, and pectins
• Clarification of juices and wine
• Size-based product
• Fractionation
• Endotoxins removal from API/
• Injectables
• Products purification, decolourization
• and concentrations

Cross-flow nanofiltration is a pressure–driven membrane process capable of separating divalent from monovalent anionic salts such as sodium sulphate, sodium chloride, etc., including uses such as groundwater softening, desalting of organic process streams (to separate dissolved salts from an organic solute) – when the organic solute has a molecular weight between 150 to 1000 (mainly the MWCO range in which NF membranes are available).

• Precious metal recovery
• Caustic and acid recovery using our special HFN series
• Concentration of proteins, amino acids, and vitamins in food, beverage, and pharmaceutical industry
• Dye concentrations and desalting

Cross flow Reverse Osmosis is a pressure–driven membrane process capable of separating water from its solutes, in applications such as desalination of seawater, brackish water, etc. In process applications, RO plays an important part in the concentration and dewatering of dilute solutions as an upstream,
