Water is one of the most important, if not the most important thing in the world in order to survive. As they say, ‘water is life’. It symbolizes many things and has various meanings in different societies. Most of us think of water as a sign of serenity, peace and softness. In modern times today, many of the households want to soften their water. But how is this possible? Do we need water softeners? How do water softeners work?
Water is described as ‘hard’ when it is found to contain magnesium, calcium and other types of minerals. The water gets these minerals by disintegrating them from some rock and soil. The hardness of the water is measured in terms of milligrams per liter and some in terms of grains per gallon. As the water vaporizes, it parts with the minerals that it picked-up earlier, causing the minerals stick to your appliances. Soft water is preferred by many because it helps save on energy and electric expenses, and has the capacity to increase the soap’s foaming abilities. Washing clothes and dishes will then require less amount of soap. Hard water, on the other hand, if mixed with soap, tends to leave lime and soap rabble on your sink.
No need to worry because water softeners are now available. But how do water softeners work? Water softeners work best when there is ion exchange. This ion exchange takes place inside the tank, with beads known as zeolite. Positively charged sodium ion is bonded to the zeolites because they are negatively charged. Regeneration of the minerals take place as it hits its maximum capacity. Here’s a detailed regeneration cycle that may help you understand more how do water softeners work.
This is when the device on top reverses the flow, closing the device from the supply of water. This is a way of redirecting the flow of water and putting the beads inside the tank.
This is the second step in explaining how do water softeners work. This time, the device will remain as how it had been in the first step and the brine device will open to allow the salt solution to stream through the zeolites. This will then start to push the magnesium and calcium off the zeolites as they are charged with the sodium ions.
Here, the device switches to lead the water to the right flow direction. Next step is to rinse slowly the remaining brine, magnesium and calcium to ensure proper flow of the zeolites.
After rinsing slowly, this step is done to make sure that the resin settled at the bottom of the tank.
This time, the device used for draining closes, allowing the service valve to open. The flow meter will start from the beginning, depending on how you have set-up your water softener.
This is just a quick overview on how do water softeners work. Set-up one now for a better water quality.
