Cleaning, Disinfection & Preservative Solution Guidelines

• Preservative Solution: Composed of water/glycerol/sodium metabisulfite. Cleaning involves draining slowly with feed water for a minimum of 4 hours, using at least 14 m³ of feed water.
• Disinfection: Chemically disinfect against biological contamination using 100 ppm sodium hypochlorite solution, circulated for 10 minutes, then soaked for 1 hour. Module must be drained until filtrate line is free from chlorine.
• Start-up: Backwash procedure with treated/clean water is advised.
