Web1. The crossflow filtration of whey and model solutions with RO membrane was carried out. The pH condition of whey is one of the most remarkable causes for decreasing the permeate flux. Around pH = 6, the permeate flux decreases due to the precipitation of calcium phosphate. The precipitation of calcium phosphate is controlled by adding EDTA … Cross-flow membrane filtration technology has been used widely in industry around the globe. Filtration membranes can be polymeric or ceramic, depending upon the application. The principles of cross-flow filtration are used in reverse osmosis, nanofiltration, ultrafiltration and microfiltration.

WebSep 1, 2011 · A common misconception of pressurized filters is that they provide the best filtration at a flow rate of 5 gpm/ft2. Actually, filter performance will keep improving as the flow velocity is reduced until reaching the limits of the ability of the distribution laterals to prevent channeling. WebJul 24, 2013 · In a system where the permeate flux is maintained by increasing TMP, the energy required to achieve filtration increases. Over a long period of operation, membrane fouling is not totally reversible by backwashing. As the number of filtration cycles increases, the irreversible fraction of membrane fouling also increases.
