Details of Construction

(1) 3-Cycle-Valve
SPRING FRESH uses a non corrosive single lever six way valve that operator in three cycles : softening , brine draw and regeneration, and rinse. The water flow rates during these phases are controlled by built in flow restrictors. These valves are non corrosive and are easy to operate.

(2) Pressure Vessels
SPRING FRESH uses non - corrosive composite and Fiber Reinforced Polyester pressure vessels. These multi-wall light weight vessels are capable of withstanding pressures upto 10 Bar (150 psi) and being non - corrosive are guaranteed to give long-lasting performance. SPRING FRESH also offers models in Stainless Steel (SS316) Vessels.

(3)Softener Resins
SPRING FRESH uses international quality polystyrene cationic resin suitable for softening drinking water and water used for food processing. The principal characteristic of these resins are high exchange capacity and excellent regeneration efficiency.

(4)Salt Storage
Tanks he high capacity HDPE Salt Storage Tanks allow extended periods between salt refills . These tanks are resistant to corrosion from salt, acids and alkalis.

(5) Brine Well
A perforated HDPE tube provides direct contact between the salt and the water to produce concentrated brine for regeneration

(6) Brine Director
The Brine Director injects a pre-set quantity of soft water into the brine well to form brine for the next regeneration. The dosing system allows the correct quantity of brine, in proportion to the quantity of the resin to be regenerated, to flow into the softener on regeneration. The Brine Director is fitted with a safety device with a valve and mechanical float to prevent any risk of the salt storage tank overflowing.

 

 
  Operation

SPRING FRESH Softeners treat hard water by a physico-chemical process. When the valve is set on a service mode, hard water passes through the resin coloumn which is filled with a food grade cation softening resin in the sodium form. The resins absorbs the calcium and magnesium ions from the hard water and releases the sodium ions into the water , thus softening the water. When the resin has completely exhausted its sodium ions, it needs to be recharged and the valve is set to the regeneration mode for approx. 30 minutes. In the regeneration mode the sodium salt is fed into the resin coloumn and the resin releases the calcium and magnesium ions and is charged with sodium ions. Then the valve is set to the rinse mode which removes the brine remaining in the coloumn until required quality is obtained.

 
  SPRING FRESH Softeners have numerous advantages over conventional softeners, namely:
  • Corrosion resistant FRP /Stainless Steel Pressure vessel gives long-lasting service.
  • Corrosion resistant single lever six way valve made from enginee4ring plasrics is easy to operate
  • Fittings, piping and accessories made from corrosion free PVC materials for long service.
  • Efficient production of soft water.
  • International quality resins suitable for drinking water systems release no substance that could alter the organoleptic properties of treated water.
  • High exchange capacity and excellent regeneration efficiency minimises salt consumption.
