Several developing non-chemical technologies based on a variety of physical phenomena have recently hit the market to assist customers in dealing with the challenges created by hard water. Several developing non-chemical technologies physical phenomena have recently hit the market to assist customers. These devices use electricity, although at a lower rate than ordinary household appliances. These devices get often installed at the point of entry. They treat all water entering a home or all water going to a water heater. Water softeners without salt alternatives can get divided into four categories, each of which gets addressed below.
Electrically induced precipitation is a method of precipitating water hardness and other substances using a direct electrical current. Hardness precipitates on an electrode, which must be cleaned regularly. Precipitate creates a soft sludge on surfaces, such as a heating element, that is easily removed by fast running water near the surface, according to certain research.
Using electricity, electrochemical water treatment devices remove dissolved hardness minerals and other pollutants. Continuous electrolytic deionization, capacitive deionization, and electrically regenerated ion exchange are all terms used to describe the method. When a negatively charged electrode, or cathode, is introduced into water, positively charged cations will gravitate towards it.
Surface-treated resin beads are used in template-assisted crystallization to convert (not remove) dissolved hardness ions into small-scale-resistant crystals. The fluidization of the polymeric beads causes agitation, which releases the small crystals and allows for additional crystal formation. These crystals are insoluble particles that will not develop scale on surfaces once they have been created and liberated from the beads.
Water is treated using magnets and electromagnetic equipment in magnetic water treatment, a controversial water treatment technology. As a result of the magnetic field, microscopic precipitates are created, which are less likely to accumulate on water heaters, pipes, and other plumbing fixtures as a result of hard water. The scientific consensus is lacking when it comes to the effectiveness of magnetic water treatment and its elimination methods. Magnetic water treatment, in contrast to the other technologies described above, has yet to be demonstrated.
Literature supports the use of some of these devices as anti-scaling treatments on an industrial scale. These devices, which are new to the residential market, have not been subjected to standardized testing procedures. Water quality and water use patterns vary widely between homes, making it difficult to predict which devices will work in each home.
These no-salt solutions have some promise for customers, but they’re not without the drawbacks that come with new technology. In certain circumstances, one of these goods may be quite effective, while in others, it may fall short of the consumer’s expectations. As a result, before purchasing a certain item, buyers should thoroughly evaluate product claims.
