What are the negative impacts of traditional salt-based water softening systems?
  • Softened water is not healthy to drink—not only for sodium-sensitive, hypertensive patients, but also for healthy people as well. For hypertensive people on a low-sodium diet, softened water contains sodium. But softened water may also contain metals (such as lead and copper), which have been leached from the metal pipes, faucets, and soldered joints of the pipes in the home.
  • Water-softening polymeric resins do not last forever. In general, the polymeric resins in traditional salt-based water-softening systems have to be replaced every five to 10 years (depending on the hardness of water being treated and the other factors discussed previously) because the resins have been "spent" and cannot be regenerated any further. It is clear then that salt-based water softeners are not an ideal, permanent solution to the hard-water problem.
  • During regeneration, the calcium and magnesium ions which are discharged with the rest of the household sewage may precipitate out as hardness scale on the inside of the sewage and discharge pipe. As a result, the part of the household plumbing that connects with the municipal sewers may have scale buildup as well. Traditional salt-based water-softening systems are not environmentally friendly. The salt contributes to the salinity problem when discharged with other wastewater into the municipal sewage-treatment plant. In general, higher salinity in the wastewater increases the treatment costs and reduces the potential for reuse of treated wastewater for irrigation and industrial purposes.
  • Salt is a major pollutant—in many states (including California), salt is considered a pollutant when discharged into the environment. As we know, when hardness or salinity rises, soaps and detergents become less effective, home appliances and plumbing wear out faster, and water-heating systems become less energy efficient due to scaling. When discharged with treated wastewater into rivers and lakes, chloride (Cl-) can harm aquatic life and damage agricultural crops by causing leaf burn of drying of leaf tissue, thus reducing crop yields.
