Process Steps

The datasheet outlines three main process steps with specific valve positions:

1. Production:
   • Forward Flush: Rinsing with feed water.
   • Filtration: Production phase.
2. Backwash:
   • Drain: Module drainage.
   • Air Scourge: Membrane scouring with air.
   • Backwash-Bottom: Rinsing with permeate water (top to bottom flow).
   • Backwash-Top: Rinsing with permeate water.
3. CEB (Caustic/Chlor/Acid):
   • Drain: Module drainage.
   • Air Scourge: Membrane scouring with air.
   • Backwash-Bottom: Rinsing with permeate water and chemical (top to bottom flow).
   • Backwash-Top: Rinsing with permeate water and chemical.
   • Soak: Membranes are soaked with all valves closed.
   • Drain: Module drainage.
   • Air Scourge: Membrane scouring with air.
   • Backwash-Bottom: Rinsing with permeate water (top to bottom flow).
   • Backwash-Top: Rinsing with permeate water.
