SPECTRUM
5, 7 or 12
softening
control valve
GRP valves with great corrosion resistance,
operates with 5.5V DC transformed electrical
power for SPECTRUM 5
7.5V transformed for SPECTRUM 7 and 12
valves
• 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 ow, 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 efciency
• 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.
Rell: Rell the brine tank with water to dissolve salt for
the next regeneration
Valve Operation Mode Softener: Standard water softener operation
Regeneration Mode Volumetric immediate or delayed with electronic timer
Water Hardness can be adjusted
User can adjust the mixing valve to get desired outlet water
hardness
Display Format Metric
Media NSF 61 and FDA approved SPECTRUM resin Food grade SPECTRUM softening resin
Pressure
Vessel
• NSF 44 tested and certied
• Polyethene material manufactured for the
Food & Beverage industries
• Light, high pressure resistance
• Strong corrosion resistance
• Polyethylene liner with reinforced berglass
Pressure vessel holds the resin and a distribution system
Riser Tube &
Distribution
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 overowing
• Water and salt mix in the brine tank. Salt will dissolve
continuously until the water is saturated by salts
