UV-ASSISTED GRAFTING OF PES AND PSF MEMBRANES

Ultrafiltration (UF) membranes have found widespread use in the food and biotechnology industries. UF has been applied in the processing of normal and transgenic milk, cheese and eggs, whey and potato protein recovery, the clarification of juices and wine, the recovery of proteins from animal blood, and the purification of water. UF is also used in the biotechnology industry for the recovery of biological products through such steps as cell broth clarification, cell harvesting, concentration or diafiltration of protein solutions prior to separation, and final concentration.
