Stated simply, hard water is water that is hard to lather, and soft water is not. A more technically accurate definition of soft water describes the physical removal, to less than 1 grain per gal (gpg) in most cases, of calcium and magnesium salts. If you cheat and go to the end of this article, however, future generations’ definition of soft water might read “less than 4 gpg, as defined by the U.S. Geological Survey.”
Softening Through the Years
New technologies offer dealers opportunities to maximize efficiency for customers
If you attended the WQA Aquatech USA 2013 tradeshow in Indianapolis in April, you heard about many exciting topics, but probably none that have been in the works for as long as the septic study. After more than 10 years in the making, the Water Quality Research Foundation published results from the Environmental Impact Study that was funded to investigate the effects residential ion exchange water softeners may have on the performance of onsite septic tanks.
Septic study results show systems working together efficiently
The Hybrid DI with Crosscharge technology offers the benefits of traditional water softening and RO in a single system without requiring salt. This capacitive deionization system uses low-voltage direct current to deliver bottled-quality water where cost and space limitations are key considerations.
Nelsen Scale Prevention Systems utilize Filtersorb SP filter media to first remove already existing scale from pipes and heat exchanger surfaces and then to further protect the system from future formation of scale. Filtersorb SP is based on a process that changes the chemical structure of scale-forming minerals. This technology is so effective that it requires a contact time of only seconds.
West Fraser Mills in Williams Lake, British Columbia, Canada, received a demand order from the province’s Workmen’s Compensation Board to have potable, disinfected water available at all locations in its sawmill, including in the dust suppression misting system.

Nearly everyone involved in the restaurant industry has an interesting experience to tell. One such situation occurred in the northeastern U.S., in a town where serious water contamination issues were found in the municipal water (and were later immortalized in the John Travolta film, “A Civil Action”). A customer walked into a local restaurant years after the situation was resolved. When the customer approached the counter, the following dialogue took place:
RO treatment system provides high-quality water for better ice
Independent testing concludes that systems can work well together
Water softeners set with appropriate salt efficiency do not harm septic systems and may actually help them, according to a new study released at WQA Aquatech USA 2013.
The IQsoft Series of cabinet water softeners includes four models sized for installation in narrow locations. The timer can stay on the unit when the cover is removed, making it possible to test the control valve during maintenance. The series features an overflow elbow integrated into the cabinet body, a two-line backlit display and a salt reminder that displays when salt levels need to be checked.
The Legionella bacterium, Legionella pneumophila — the fundamental agent of Legionnaires’ disease — is a water-based organism that causes infection when inhaled in aerosol form. Legionnaires’ disease acquired its name in 1976, when an outbreak of pneumonia occurred among attendees of a convention of the American Legion in Philadelphia. Later, the bacterium causing the illness was named Legionella.

The WS1 Twin Alternating control valve maximizes softener capacity and optimizes salt efficiency. This 1-in. valve provides a service flow rate up to 30 gpm and a backwash flow rate up to 16 gpm, with the meter and bypass installed. It has backwash and brining capabilities up to a 21-in.-diameter mineral tank. It incorporates patented seal-spacer stack assembly and patented technologies from the WS1 and WS3 valves.
