BEFORE - Existing Softeners During Tearout |
AFTER - New Dual Res-Kem Softeners Installed After Building Refurbishment |
Water treatment
application:
|
Replacing 25 year old zeolite softeners
|
Savings and/or ROI
the customer wants to achieve
|
Clean up the zeolite operations and the room where they
reside. Automate the regeneration process and the monitoring of the water
softeners
|
Operating
conditions:
|
60-120 gpm boiler make-up
|
System
configuration:
|
Singe or Dual Parallel operation PLC controlled
|
Materials of
construction:
|
Since the source water being well water and the room
ambient air temperature can be very hot > 95 F, condensation that can form on the tanks, therefore fiberglass tanks were used.
Schedule 80 CPVC was used to provide more strength to the
system piping
Valves were Bray butterfly valves all stainless wetted parts
|
Threaded or welded:
|
Glued, Schedule 80 CPVC
and flanged unit piping
|
Type of valves and
actuators:
|
All Bray valve Lug style, 150 ANSI flanges.
Solenoid were mounted directly on each valve to save
wiring costs back to panels
|
Control philosophy:
|
The plant standardized their automation based upon
Rockwell automation, so we provided the regeneration sequence and the
necessary P&ID so their in-house PLC programmer. His
panel shop could outfit a local panel and Ethernet connection back to the
main powerhouse control room.
