NEW "SMART" WATER SOFTENERS REDUCE SALT AND WATER USAGE

 ST. PAUL, Minn., Aug. 10 /PRNewswire/ -- Water softening technology has seen little change -- until now. Thanks to a computer chip and some re-engineering of the water softening process, one manufacture has created the next generation of environmentally minded water softening equipment that saves on salt and water usage. New, demand-initiated, computer-controlled softeners are able to predict household water usage and program themselves for maximum efficiency.
 More than 85 percent of American households have water that is considered to be hard, meaning it has a high content of pipe-clogging minerals. Soft water is produced by running water through an ion- exchange filter that absorbs "hardness" minerals. This softening allows soaps to work more effectively and appliances to last longer by reducing mineral deposits.
 However, the ion-exchange filter must be regularly flushed and recharged with salt water to remain effective. Most American households have time-clock softeners which recharge the filter at preset times whether or not it is needed, thereby wasting salt and water. The demand-initiated, computer-controlled softener only recharges the filter when needed. Using a computer chip, the softener creates a historical record of water usage patters in the home and, guided by a sophisticated algorithm program, estimates the amount of water soft water that will be needed the following day. It also recharges only the portion of the filter tank that will be needed whereas most other softeners recharge the entire filter, whether it's necessary or not.
 A recent study conducted by the Los Angeles Department of Public Works showed that a demand-initiated, computer-controlled softener called the Series 3000, manufactured by EcoWater Systems of St. Paul, used 44 percent less water and 45 percent less salt than a conventional time-clock softener. "This softener sets a new standard in residential water conditioning for today's environmentally conscious society," said Ed Fierko, president, EcoWater Systems. "The unit's 'what you need, when you need it' approach takes efficiency to its highest level yet."
 In addition to using a computer chip, the new softener is designed to operate more reliably than conventional softeners. Its water flow valve has been designed with fewer moving parts, down from 85 to 25, making it less prone to malfunction. The unit also recharges its filter using a different method than conventional softeners, which increases its hardness-reducing capability.
