純水膜結垢 (維修) 技術
Technical explanation
Technology to remove and clean filter membrane fouling:
1.) Check and replace the pretreatment equipment (fouling of the filter membrane may be caused by lack of pretreatment or equipment failure). Some common examples are given below, please check and repair these devices as needed:
•Activated carbon powdering
•Water hardness increases (ion exchange resin needs to be replaced)
•Pre-treatment membrane cracking
•The pore size of the pretreatment filter membrane is too coarse
•Mechanical damage inside the pump
•Residual chlorine breakthrough and penetration
2.) Adjust equipment operating conditions (fouling can also be caused by improper system design and maintenance). Scaling can be minimized by implementing one or more of the following steps:
•Reduce recycling percentage
•Reduce system working pressure
•Pre-treatment equipment needs to be replaced more frequently
•Regularly disinfect the system
The concentration of all impurities (dissolved and suspended) in the incoming water will be highest near the filter surface. When the osmotic force passes through the filter membrane and becomes pure water, all impurities remain near the membrane surface. The water layer next to the membrane surface (boundary layer) becomes more and more concentrated (dissolved and suspended impurities). These concentrations reach a certain stable concentration, which is determined by the water inlet rate, membrane recovery percentage and membrane permeate flux (gallons of permeate per square foot per day).
Be sure to follow the membrane manufacturer's recommendations for minimum inlet water flow, maximum membrane recovery percentage, and maximum membrane flux. These recommendations are based on the size and quality of the membrane being used to treat the water supply. The concentration of dissolved and suspended solids in the boundary layer controls filter membrane performance. Higher concentrations mean higher osmotic pressure, a higher tendency for suspended solids to solidify and coat the membrane surface, and a higher likelihood of scaling occurring. Maintaining correct membrane operating conditions is a key preventive measure to reduce membrane fouling.
