SPECTRUM
7 softening
control valve
• FDA compliant GRP valve
• Strong corrosion resistance
• Innovative design
• CE marked
• 24 hours control and monitoring with a timer and meter;
automatically regenerates the media bed once the
capacity of a pressure vessel expires
• Cycle Process:
• In service: Once the water is supplied with correct
pressure and flow, the cations contained in hard
water will be replaced by Na
+
in regenerants, then the
softening system will supply softened water through its
outlet
• Backwash: When the ion exchange resin has been
exhausted, the resin bed needs to be regenerated.
Before the regeneration of the resin bed, a backwash
step is necessary for two main purposes; removing the
residue in the resin bed and loosening the impacted
resin bed for better regeneration efficiency
• Rinse: Rinse the resin bed to remove the residual
regenerant (salt) after the brining step until the water
from outlet contains no regenerant; rinse could also
compact the resin bed for a better softening effect.
Refill: Refill the brine tank with water to dissolve salt for
the next regeneration

System
A riser tube and distribution system disperse water evenly
through the resin bed
Brine Valve
& Tank
• High pressure resistance
• Prevents the brine tank from overflowing
• Water and salt mix in the brine tank. Salt will dissolve
continuously until the water is saturated by salts
