Entfestigungsmechanismen water is often very useful, because there are a number of advantages, particularly reduction in construction and sometimes the taste. However, softening it also has a certain impact on human health and the environment that are important to consider .

The hard water to be treated through a bed of the resin, the sodium and potassium ions. Since the water through the resin, the hardness ions in the resin and the sodium or potassium ions in the water - softening effect. The harder the water, the more sodium or potassium ions from the resin and into the water.

Effect on humans

For people with a low sodium diet, the increase in sodium levels (for systems releasing sodium) in the water can be considerable, especially when dealing with very hard water. A contribution from Kansas State University shows an example: "A person who drinks two liters (2L) of soft, extremely hard water (30 to assume gpg) consumes approximately 480 mg more sodium (2L x 30 x gpg 8 mg / L / gpg = 480 mg) than if unsoftened water is consumed. "" That is a substantial amount, as she stated that: "The American Heart Association (AHA) suggests that 3 percent of the population, has a severe, salt -- restricted diet should not exceed 500 mg of sodium per day. AHA suggests that no more than 10 percent of the sodium intake should come from water. The draft Directive of 20 mg / l for water protects people who have the most. "

Impact on the environment

Over time, the resin gradually lose their effectiveness and must be regenerated with a concentrated brine solution, which through them. Most of the salt for the regeneration will be flushed from the system and can be used in the soil or the sewer. This process can adversely affect the environment, especially in arid regions. Some countries prohibit such release and require users spent on the brine at an approved site or use a commercial service company.

Most manufacturers provide metered water control valves to the frequency of renewal. It is also possible on most units, so the amount of salt for each regeneration. Both steps are recommended to the effects of water softeners on the environment.

In the industrial-scale water softening plant, the effluent from the reform process can be important. Under certain conditions, such as when the waste water, in admixture with domestic sewage, the calcium and magnesium salts in May reflected a hardness scale on the inside of the discharge pipe. This may be to such an extent as to block as the pipe on a large industrial facility in Australia in the 1980s. I do not want the person who cleaned that line!

To summarize

While there are advantages for the softening of water, there are consequences that must be taken into account, both for humans and the environment, as outlined above. In my opinion, the benefits of softening probably outweigh the disadvantages, as long as one realizes that it directly effects the quality of the water and the minerals contained therein. People who have tight control over their food (especially their sodium intake) must be aware of this. Also water softening devices are very helpful in the prevention of the hardness minerals, which removes hard water stains and limescale problems. You do not have significant effects on the environment compared to the much larger equipment in the industry.
