Guidelines

• The module must be filled with storage/preservative solution during shut-down.
• At least half capacity must be produced in the first production. If necessary, permeate water and preservative solution must be drained completely.
• Do not operate the module above the pressure limits to avoid membrane deformation.

Cleaning of Preservative Solution

• Preservative Solution Composition: Water/glycerol/sodium metabisulfite.
• Procedure: Drain the module slowly with feed water for a minimum of 4 hours. The used feed water volume must be at least 1.8 m³.

Cleaning-Disinfection

• Procedure:
  1. Circulate 100 ppm sodium hypochlorite solution for 10 minutes.
  2. Allow the solution to soak inside the module for 1 hour.
  3. Drain the module until the filtrate line is free from chlorine.
• Note: A backwash procedure with treated/clean water at start-up is advised.

Process Steps

1. Production

• Forward Flush: The module is rinsed with feed water.
• Filtration: The production is done.

2. Backwash

• Drain: The module is drained.
• Air Scourge: The membranes are scoured by air.
• Backwash-Bottom: The module is rinsed with permeate water (flow direction: top to bottom).
• Backwash-Top: The module is rinsed with permeate water.

3. CEB (Caustic/Chlorine/Acid)

• Drain: The module is drained.
• Air Scourge: The membranes are scoured by air.
• Backwash-Bottom: The module is rinsed with permeate water and chemical (flow direction: top to bottom).
• Backwash-Top: The module is rinsed with permeate water and chemical.
• Soak: All valves are in closed position; membranes are soaked.
• Drain: The module is drained.
• Air Scourge: The membranes are scoured by air.
• Backwash-Bottom: The module is rinsed with permeate water (flow direction: top to bottom).
• Backwash-Top: The module is rinsed with permeate water.
• Forward Flush: The module is rinsed with feed water.
