Maintaining Dow reverse osmosis (RO) membranes ensures optimal performance and extended lifespan. Start with regular pre-filter replacements to prevent particles from reaching the membrane. Periodic cleaning with approved solutions removes accumulated scale and fouling, preserving flow rates and salt rejection efficiency. Monitor pressure drops, as increased pressure often signals clogging. Conduct routine inspections for physical damage, and avoid exposure to chlorine or oxidants, as these can degrade the membrane material. Adequate storage in preservative solutions during downtime prevents bacterial growth. By following these practices, you can sustain high-quality water output and prolong the membrane's effectiveness.
