Water Softeners

WSS-Series
Steel Tank Water Softener
The WSS-Series is designed to remove
total hardness (calcium and magnesium)
as well as trace metals from water. Salt,
in the form of a brine solution, serves as
the regenerant because it contains the
large number of sodium ions necessary
to remove the hardness ions from
the resin.
Vessels
WSS-Series vessels are constructed of high quality carbon steel
with flanged and dished heads. The 24" and smaller vessels
have two 6" handholes to permit loading of media and
inspection of internals without disturbing main piping. The
30" and larger vessels have a bolt and yoke manway in the
top head to permit loading of media and inspection of internals
without disturbing main piping and a 3" diameter media
removal pad flange in the lower side sheet. Vessels include
structural legs.
Distribution
WSS-Series 24" and smaller vessels are provided with an
inlet/regenerant and outlet distributor. The 30" and larger vessels
are provided with separate inlet, outlet, and regenerant
distributors. The distributors are designed to direct flows
uniformly over the entire bed with a minimum pressure drop.
WSS-Series distributors are constructed of Schedule 80 PVC.
Media
All softeners have a 36" or 60" total bed depth when the
height of the straight side of the tank is 60" or 96",
respectively. The cation resin is a high capacity type, designed
specifically for water softening. A bed of quartz protects the
bottom distributor. The quartz media also provides for a means
of collecting and distributing the water for service and
backwash, respectively. High quality quartz is provided,
containing low levels of extractable materials, preventing
contamination of product water.
Piping
Standard configuration piping is Schedule 80 PVC with socket
welded fittings except where the attachment of threaded valves,
rotometers and other devices is needed.
Automatic Valves
Diaphragm valves are provided for 2" piping and smaller;
butterfly valves are provided for 3" piping and larger. Backwash
and rinse outlet valves are equipped with travel stops to regulate
flow rates during backwash and rinse cycles. An air pressure
filter/regulator is provided. Clean air at a minimum pressure of
80 psig is required for valve actuation. All tubing is polypro.
Controls
A PLC controller will be provided, fully wired and programmed.
All regenerant times have been programmed into the unit. All
automatic valves are solenoid operated and include manual
overrides.
Regenerant
Brine is transferred from a day tank to each water softener
unit and diluted to proper concentration by a hydraulic eductor.
Additionally, a manual valve is provided for flow control.
