There are three types of home water treatment systems: water softeners, reverse osmosis treatment systems, and point of use filters. Water softeners are designed to solve hard water problems that somehow can pose problems on the effectiveness of soaps, detergent and shampoos and carbonate deposits on plumbing fittings and fixtures, especially when these fittings are connected to water heaters and boilers.
Hard water is a type of water that contains a high percentage of calcium carbonate and magnesium carbonate. Water above 120 ppm (parts per million) is considered moderately hard water and greater than 171 ppm is classified as very hard water. When hard water deposits are embedded in fittings of water heaters and boilers, this can cause significant energy inefficiency, where energy is not optimized well. Therefore, the best way to prevent hard water presence is to install a home water softener. The process of water softening involves exchanging calcium and magnesium minerals present in the water.
The reverse osmosis is a separation and water treatment process that uses pressure to force water through a membrane that retains the solute particles of water on one side and the purified water to pass through another side. The membrane used to separate the solute from the purified water is made up of a dense barrier layer in the polymer matrix where the separation occurs. When the membrane is filled with filtered solutes, the system must go through a rinse cycle to clean the membrane filter. Water that is used in the rinsing cycle can equal to about 25 to 75% of volume amount of the purified water that reverse osmosis system produces. Get more information here!
Point of use filters are small water filters that are attached to an individual faucet or filter water into a dispenser. The purpose of point of use filters is to remove chemicals and metals such as chlorine and lead for health reasons. There are a variety of filter types, like granular activated carbon filters, metallic alloy filters, microporous ceramic filters and carbon block resins.

Among the three types of home water treatment, the water softeners and reverse osmosis system makes use of water in the treatment process, which is the opposite of the point of use of filters that is just a simple device that is attached to a faucet. The average water use for homes that are equipped with a water home treatment unit was 15.8 gallons per day per household. Check this site to know more!
