    • 0.1 % NaOH + 0.2 % NaOCl
    • 0.2 % HCl, 2 % Citric Acid
  • Cleaning Flowrate per Module: 1-2 m³/h

Preservative Solution Cleaning

• Preservative solution is composed of water/glycerol/sodium metabisulfite.
• For cleaning, the module is drained with feed water for a minimum duration of 4 hours.
• The feed water specifications must be maintained, and the used feed water volume must be at least 14 m³.

Disinfection

• The module should be chemically disinfected against biological contamination.
• Circulate 100 ppm sodium hypochlorite solution for 10 minutes.
• Allow the solution to soak for 1 hour inside the module.
• After disinfection, drain the module until the filtrate line is free from chlorine.

Operation Guidelines

• In initial production, operate the permeate water and preservative solution at half capacity until completely drained.
• Do not operate the module above the pressure limits to avoid membrane deformation.
• To obtain designed production capacity and water quality, operation parameters must be maintained.
• The module must be filled with storage/preservative solution during shut-down.
• A backwash procedure with treated/clean water at start-up is advised.
• Valve positions and specifications must be maintained as per process steps.
• CEB frequency must be determined based on feed water quality.
• Chemical solutions for cleaning can be either filled directly into the module or circulated using a vessel and pump for up to 2 hours.

Process Steps

• Production: Includes Forward Flush (rinsing with feed water) and Filtration.
• Backwash: Involves Drain, Air Scourge (membranes scoured by air), Backwash-Bottom (rinsing with permeate water, top to bottom flow), and Backwash-Top (rinsing with permeate water).
• CEB (Caustic/Chlorine/Acid): Consists of Drain, Air Scourge, Backwash-Bottom (with permeate water and chemical, top to bottom flow), Backwash-Top (with permeate water and chemical), Soak (all valves closed, membranes soaked), Drain, Air Scourge, Backwash-Bottom, Backwash-Top, and finally Forward Flush (rinsing with feed water).
