Evaluation of Alternatives to Domestic Ion Exchange Water Softeners Evaluation of Alternatives to Domestic Ion Exchange Water Softeners Many communities are concerned about the rising concentration of total dissolved solids (TDS) and associated ions and salts in wastewater collected and received at their water reclamation facilities. TDS and its components have the potential to restrict the benefi cial use of reclaimed water, increase water management costs, and decrease the economic and environmental sustainability of a region. Point-of-use water treatment systems, in particular home and commercial ion exchange water softeners, have been identifi ed as a potentially controllable source of TDS. Communities are seeking credible alternatives to ion exchange water softeners that would provide consumers with the ability to reduce the impacts of hard water without creating the negative salinity impacts. There are many products using alternative technologies to ion exchange that may be capable of reducing hardness scaling. However, most of these products do not provide suffi cient technical data to support advertised claims. Previous academic research has supported a number of treatment processes, but has not clearly defi ned the parameters for reproducing results at locations with diff ering water chemistry and fl ow rates. Additionally, there is a lack of U.S. standards for testing non-ion exchange devices to confi rm hardness removing effi ciencies and eff ects. This proposed research project will evaluate some of the more promising alternative technologies against three diff erent water qualities to fi ll part of this data gap.
