Process Description: (2-Valve Control) Start process in ‘Auto’. Select SS-1 to “Auto”, depress PB-1 “System On/Off” once to start. The system will go through the following sequence. P1 – Feed Pressure P2 – Air Scouring Pressure P3 – Backflush Pressure Filtration cycle ( T1 ) (Refer to Filtration Flow Diagram Page 8) Produce Filtered Water...

Air Scouring + Backflush cycle ( T3 ) (Refer to Air Scouring + Backflush Flow Diagram Page 10) Membrane Regeneration CV-1 Open, CV-2 Close, Feed Pump Off, Backflush pump On, Blower On Inside to outside flow, on a dead-end configuration. Backflush cycle will pump product water through the membrane cartridges through Reject valve CV-1 for disposal.
Membrane Regeneration After some time of usage, and depending on the feed water conditions, the membrane cartridges may experience fouling. This will result in a drop in product flow rate and/or an increase in filtration pressure. A regeneration procedure can be performed to reverse this situation.
Membrane Regeneration 4.2 Enhanced Backflush “EBF” (Refer to EBF Flow Diagram Page 13) EBF is a process of backflushing the membrane cartridges with a preferred chemical for cleaning purpose. This regeneration process will reverse the fouling issue. It should be implemented as a routine during the usage of this system.
4.3 Clean In Place “CIP” (Refer to page 15 & 16) CIP is a process of cross flowing the membrane cartridges with the preferred Chemicals for cleaning purpose. This regeneration process will reverse the fouling issue. It should be implemented as a routine during the usage of this system. Depending on the feed water conditions and system performance, it should be performed on a routine basis.
