was explored, but rejected due to the high capital and operating
costs required. CWS designed a special type of water
softening system, using potassium chloride instead of sodium
chloride as the regenerant. |
| Water softening,
a type of ion-exchange, typically uses sodium chloride to restore
the softening resin. With sodium chloride, the sodium ion is exchanged
for the calcium and other positively charged ions. Sodium, however,
can be potentially harmful to plants if the sodium builds up in
the soil or hydroponic medium. This system uses potassium chloride
in place of sodium, and potassium is exchanged into the water
for the calcium and magnesium, making the water suitable for irrigation
and plants. |

| As a final
step, the pH of the water is lowered to 6.0 to prevent the
formation of potassium bicarbonates. The result is a beautiful
product quality at greatly reduced operating costs over
reverse-osmosis, saving thousands of dollars in capital
costs associated with the purchase of a reverse-osmosis
system. |
