subject: Types Of Water Purifying Systems [print this page] Water purifying systems can effectively help improve the quality of your drinking water, which is vital for your overall wellness and health. However, it is important to note that using these systems can introduce dangerous carcinogenic components, which can be poisonous to your health.
Home water purifying systems come in different types - ranging from simple systems that need less maintenance to extremely complicated ones. Selecting the right type should depend on the water quality available in your neighborhood. There are a lot of people who use tap water for drinking but if you decide to use water filtration, you can find such systems in the market today. There are some systems that can help purify the water to eliminate the bacteria and contaminants from your drinking water. On the other hand, there are systems that can provide purified water that tastes better.
Types of home water filtration systems:
Distillation
Water distillation was derived from the hydrological cycle of nature. It is known as one of the most efficient ways to purify water. Distillation is the process of eliminating a wide variety of contaminants such as inorganic, biological and organic contaminants. This process involves boiling of water and the condensed part of the water is the purified distilled water.
However, distilled water is known to be more acidic and it lacks minerals, making a difference in its taste. Furthermore, the process needs large systems that require a huge space on the countertops.
Ion exchange
This process softens the water and it eliminates the traces of magnesium and calcium in the water as well as some soluble iron substances. The process includes using resin beads that are made of polystyrene, which has a huge similarity to hard components found in water such as magnesium and calcium.
To begin with, sodium is used for the resin beads' regeneration. The sodium ions stick to the resin beads throughout the process of regeneration and hard water is then added to the tank that holds regenerated resin beads. Then, the magnesium and calcium ions in the hard water stick to the polystyrene resins. The sodium ion exchange happens from the resin to the magnesium and calcium found in the hard water. To make the regeneration process possible, a NaC1 solution is added in the resin bead tank.
The process of softening the water only softens the water and it doesn't treat the bacteria found in the water and this is a disadvantage of ion exchange system.
Carbon adsorption
The chlorine found in drinking water is considered as a critical issue that can be addressed with the use of the carbon adsorption process. This process involves using coal, pyrolyzing coconut and resin beads. The degree of adsorption depends on the size of the carbon filter's pores.
The process is carbon adsorption eliminates the chlorine and some organic traces in the drinking water. However, in this method, fine carbon particles may be present in the purified water.
UV filtration
The ultra violet filtration process is most popular for germicidal water treatment. For UV irradiation, low pressure lamps are utilized.
These are the different processes used in water purifying systems and in order to get the best results, it is recommended to use a combination of systems.
