Controls: The process is controlled with a PLC. There are PID loops for the inlet pressure and Concentrate Flow rate. Concentration is accomplished using VFD's and throrttling valves. The % Recovery is controlled using volumetric calculations. The system initiates upon a signal from the feed tank level sensor. The system will shut down automatically once the feed tank is emptied or the permeate tank is filled, The system will send on spec concentrate to the holding tank. After a system shut down due to low feed tank level, or after any shut down, the system would auto flush using hot water and then go into Standby Mode. On start up after flushing with water, the discharge from the V✧SEP goes to drain for a set time interval until all water has been purged. Then the discharge from the V✧SEP diverts to the appropriate holding tanks. V✧SEPs will automatically clean when a predetermined low permeate flow alarm is reached on any of the units, or at a predetermined timed interval. Spent cleaning chemcials would also discharge to the Chemical Treatment Sewer.
