However, the process uses regenerant chemicals rather inefficiently (typically less than 50% efficient) and produces a waste stream which has to be treated chemically to precipitate heavy metals prior to disposal.

Ces precipitations contribueront aussi a ameliorer les ressources hydriques de la region en regenerant les nappes phreatiques et en augmentant sensiblement le taux de remplissage des barrages.
Semiannual verification of regenerant brine introduction rate, including eductor
Ion exchange softening has two significant disadvantages: it adds sodium to the product water in exchange for calcium, magnesium, and radium, and it produces a regenerant wastewater typically having about 100 times the radioactivity level of the raw water.
The new technology is based on a hybrid deionisation (hybrid DI) process, using Pentair and Voltea technologies to combine the benefits of reverse osmosis (RO) filtration with those of a water softener - without requiring salt as a regenerant.
Skidded deionized continuous process water treatment resulting in longer service cycles and a 25% reduction in regenerant chemical usage as a result of optimized resin, process design, and adaptive controls.
Two suppressor accessories, the Suppressor Regenerant Detector (SRD 10) and Suppressor Current Controller (SCC-10) support the system.
All of these collateral, undesirable events make mandatory the analysis of every single regenerant, which clearly compromises the usefulness of this method for practical purposes.
For many years, the regenerant of choice for water softening systems was plain table salt, sodium chloride, because it was cheap and plentiful; it was also an environmental pollutant, however, and Wist (1945-2007), a chemist with a potash company in Canada, helped develop the technology for using potassium chloride instead.
