[ Hydrophilic treatment and operation mode of the MBR membrane element ]
If the customers buy the hydrophobic MBR membrane element, for hydrophilic treatment before using, treatment method is using the 95% of the industrial alcohol to immerse about 15 minutes, and then rinse with water . If not use immediately after the hydrophilic, should be sealed packaging to keep membrane wet
六. Prevent to block the membrane hole and cleaning
Through the aeration system to produce bubbles and water flow, to make the membrane silks shake and clean. At the same time ,using the intermittent operation mode,, can prevent membrane pore to block, and its possible that the system has the long-term stable operation.When the system is operating, keeping stable flow, by the pressure gauge to read operation pressure,working negative pressure -0.01 ~ -0.05MPa,when the operating pressure is more than -0.05MPa, need to clean the MBR membrane element.
