How To Use Potassium Chloride As Substitute For Salt In A Water Softener

Nearly after 20 years, potassium chloride has emerged as a substitute for sodium salts that were used since its inception. It was seen that little sodium was left in the water after the regeneration process. The same is with potassium but it is a healthy alternative for body and environment.

Since water softener’s inception, it has gained huge attention and salt is used as an agent for the regeneration process. A German Scientist Gans in 1905 that water could be softened via sodium chloride.

From the sodium was the standard choice for regeneration. However in the late 1980s as the market grew and health organizations enlighten the negative impacts of salts on the human body and environment scientist looked for alternatives.

Salt consumption got a major hike amid 1984 to 1999 and about 50% of the increase was estimated. These salts were discharged from home after the regeneration cycle which increased rapidly.

Further, it surfaced to high sodium intake that leads to hypertension, high blood pressure, etc. which diverted individuals interest to potassium usage.

An Alternative- Potassium Chloride:

To reduce the salt discharge in an environment that was spoiling soil and health, water softener manufacturers have addressed the issue and started taking initiatives.

However, new water softener technology isn’t the sole solution where brine discharge is a major concern. Here, potassium comes into rescue. It may help in decreasing salt intake and also adding an essential nutrient.

Environmental Impact:

Potassium is a healthy element for the human body and plants. Hence it is considered good from every perspective. Using potassium will decrease the salt discharge via a brine tank and over a period can overcome increased sodium issues.

Potassium chloride is the source of potash fertilizer. As per reports of 1994/95 Canada Agriculture involves 94% of potash domestically. This was calculated in the year 1996 to check what is the average use of potash in the world? It was 20,550,000 tons which clearly indicated the benefits of potassium.

Health Benefits:

Potassium is good for health which is not produced by the human body itself. It needs to be taken via a balanced diet. About 11% of potassium chloride is required by our body as a daily intake.

But the question is in this hectic and fast moving life do we actually pay attention to supplements intake? We usually binge on junk and fast food available to save time. Drinking potassium water could help you with one supplement fulfillment without changing your routine. When we drink 8 glasses of water per day containing potassium with 15 grains hardness it fulfills the requirement.

Additionally, potassium chloride reduces sodium content in water up to 90 percent which is best for people prescribed low sodium intakes. Also, doctors say that sodium should be consumed in limits as it may have negative effects on the body.
