Proper maintenance of DOW membranes is essential for ensuring longevity and optimal performance in water treatment systems. Begin by regularly monitoring feed water quality, checking for contaminants that could clog or damage the membranes. Clean the membranes using appropriate chemical cleaners based on the fouling type—organic, inorganic, or biological. Implement a routine cleaning schedule, ideally every 6-12 months, to prevent buildup. Ensure proper operating conditions, including pH and temperature, to maintain membrane integrity. Regularly inspect the system for leaks and pressure drops, which can indicate potential issues. Finally, follow manufacturer guidelines for storage and handling to prolong membrane life.
