Saltless water systems are a good alternative for those who need water treatment but prefer to avoid using salt or chemicals. There are a number of options to choose from. Some tackle scale, others are designed to handle drinking water safety concerns.
Scale Reduction Systems: Much of our water supply passes through rock, so it often contains hardness minerals like calcium and magnesium. When the temperature of water increases, the hardness minerals form scale, which clings to pipes, heating elements and fixtures. This scale buildup makes any water-using appliance that heats water (such as your water heater and dishwasher) work harder and can decrease its useful life. Scale reduction systems do not work the same as water softeners. They do not remove the hardness minerals and do not soften water; they change the structure of the minerals in the water so they don’t form scale.
RO Whole House Treatment Systems: These systems use semipermeable membranes to trap contaminants, iron, hardness and odor-causing impurities before they enter your home. Because of their expense, they are often reserved for the toughest and most complex water challenges.
Ultraviolet Disinfection Systems: These systems work by using ultraviolet light to kill microorganisms and make your water microbiologically safe to drink. While UV systems are very effective at disinfecting your water, that is their sole function. To resolve issues like hard water, iron and odor-causing impurities, you would need to add another saltless system like the SRS or a whole house treatment system.
