Whole House Water Softener
Softening your water has many benefits. Firstly, it provides you with good quality water that is relatively safe for beverages. Secondly, softened water enriches the flavor of your beverages such as tea, coffee, juices, and more. In addition, it becomes easier to cleanup after. And for shower and bath, softened water is less harsh on the skin because most chemicals would have been neutralized. Purified water is also less harsh to your laundry, which makes your clothes look new all the time.
What Is A Water Softener?
A water softener is basically what its name suggests – a substance or device that softens hard water. Essentially, a softener removes minerals and other impurities in the water. Thus, when the impurities have been eliminated, the water will be ‘soft’. Mineral-free water (or soft water) is easy on soap because there are no minerals to which the soap will attach to make the water slippery. This explains why ‘soft’ water is easier to clean and wash with.
A typical water softener comprises a water tank that has a tube attached running through the center from atop the tank downwards. There’s a distributor at the bottom of the tube where water flowing from the top of the tank collects. From the distributor, the water will then run upwards to the top and out into the faucets and then distributed to the appliances.
The material that eliminates the minerals and impurities from the water is placed between the tank’s inner walls and the outer surface of the distributor. The tank is known as a resin tank and the impurities removed are referred to as ‘resin’.
The Water Softening Process
Resin media is the material that traps mineral impurities in hard water. Usually, resin media comprises tiny beads that are glazed with sodium ions. The sodium ions bind to the magnesium and calcium ions in hard water. The ions in hard water exchange places with the sodium ions and take their place on the resin media.
Evidently, process of softening water is not complicated at all. As hard water flows through resin media, sodium ions are traded for mineral ions in the hard water to give soft water. When the sodium ions get used up, the resin media is replaced.
A control valve is fixed on the resin tank to split up the in-flowing and out-flowing water, ensuring that all unpurified water flows through the resin media before it runs through the distributor and into your home appliances. However, the control valve’s most critical role is to replenish the used sodium ions that replaced the mineral ions in the untreated water.
The control valve will set off the regeneration process once the resin bed reaches saturation levels. Regeneration basically entails the discharge of the mineral ions attached to the resin media. This discharge is done using a brine solution contained in a ‘brine tank’, which is connected to the control valve with a tube.
To release the mineral ions, the control valve pumps the brine solution drawn from the control tank into the tank with the resin media. Once the sodium ions have been replenished, the concentrated mineral solution comprising calcium and magnesium ions is drained out through a drain line.
The brine tank will then be refilled with water via the control valve and the water will get saturated with the brine in the tank.
From this description, it’s easy to see that a water softener control valve plays a critical role in the water softening process.
Having said that, it’s worth noting that a water softener cannot do certain things. A water softener cannot filter impurities with relatively big particles such as sand and sediment. The simple reason is that it is not a filter. Also, a water softener will not eliminate nitrates, tannin, and bacteria from water. This means that a water softener doesn’t make water very safe for drinking straight out of the tap. Process like reverse-osmosis and distillation will make your water very safe for consumption right out of the tap.
