WATER SOFTENERS: THE REGENERATION PROCESS EXPLAINED

Raw or untreated water passes through the mineral/resin tank and the media contained therein. This media is called resin or zeolite. The calcium/magnesium carbonate in the water (two elements responsible for water hardness) are attracted to the resin media and are removed before exiting the resin tank. When the resin beads are fully coated, they lose their ability to store hardness. It is then that the salt/brine solution is pumped through the resin tank, releasing the hardness stored on the beads and after flushing the residue during the purge cycle, the beads are recharged and ready to store hardness again.

FOUR STAGES OF THE REGENERATION CYCLE EXPLAINED

Note: Intended as the order for most systems

Stage 1 / Backwash: The initial stage of regeneration. Produced cross current to rapidly upflow or "fluff" the packed resin beads so that brine water can be evenly distributed throughout the resin bed.

Stage 2 / Brining (Salt Rinse): This is the most important part of the process. A venturi (suction) allows the brine solution to be pumped from the brine tank into the resin tank and slowly rinsed through the resin bed, releasing hardness content.

Stage 3/ Purge (Rapid Rinse): A fast rinse, purging residual brine and hardness through the drain. The resin is now ready to store hardness.

Stage 4 / Brine Refill: Water is refilled to the salt storage tank in order to make brine for the next regeneration process.

GUIDELINES FOR SETTING WATER SOFTENER REGENERATION CYCLES

The four key factors for determining a proper regeneration schedule are:

A) The grain capacity contained in the resin tank
B) The amount of water consumed in the home
C) The amount of reserve capacity allowed
D) The amount of hardness present in the water

Grain Capacity: The amount of resin, generally measured in cubic feet or 1,000 unit increments. 30,000 grains = 1 cubic ft.

Water Consumption: The use of water in the home. Computed by U. S. gallon increments. It is most efficient to determine this by obtaining an average water consumption figures on pas copies of water dept. bill statements. If this is not possible, allow for 75 gallons per day average per person and 75 gallons per day for automatic washer/dishwasher combined.

Reserve Capacity: The amount of grain capacity allowed as a reserve to ensure softened water until the delayed regeneration time occurs.

Water Hardness: The amount of calcium and magnesium carbonate and sulphide, measured in grains per gallon or parts per million.
