Question regarding RO membrane flushing during RODI water production. I have set up my system with some solenoids such that when my water reservoir is low it starts my RODI system. It initially opens a dump solenoid to dump the TDS creep water then proceeds to close that solenoid and open the one filling my container. Once the top optical sensor is closed, it does a RO membrane flush via a solenoid and virtual outlet for 2 minutes.
Here is my programming which has been working well.
StartFill ( a Virtual outlet)
If Lo_ATO OPEN Then ON
If HI_ATO CLOSED Then OFF
Defer 002:00 Then OFF
FINAL_FLUSH (a Virtual outlet)
Set OFF
If Output RO_SOLENOID = ON Then ON
If Output StartFill = ON Then OFF
RO_Solenoid
Set OFF
If Output StartFill = ON Then ON
Defer 002:00 Then ON
Defer 002:00 Then OFF
Dump_Solenoid
Set OFF
If Output StartFill = ON Then ON
If Output RO_SOLENOID = ON Then OFF
RO_MembFlush
Set OFF
If Output Final_Flush = ON Then ON
If I want the RO membrane flushed during water production for 30sec each hour would this work?Creat a Virtual outlet called FLUSHOSC with:
OSC 000:00/000:30/059:30 THEN ON
and add this line to my RO_MembFlush Solenoid
If Outlet FlushOSC = ON Then ON
Thanks!
