A Guide To Getting Pure Drinking Waterby Water Purifier Anjan Sengupta (Service Head)
Bottled water can cause harm to our environment, wallet, and our environment. If you want to kick the habit of drinking bottled water and make a move on tap water, then you must check your local water supply.
One of the best ways to find out about the local water is to read the water quality report. We all know how much the drinking water is polluted with various chemical contaminants. The best way to reduce these pollutants from entering your body is by installing a water purifier unit that matches your requirement for the safety of you and your family.
Here are a few water filtration technologies that you can try at your home.
Different water purifiers use various technologies to filter tap water. Some of them use more than one, and if you are looking for a home water filter, you might have come across some of these terms:
They consist of simple screens that block large particles. They also function as “pre-filters’” in a multi-step water filter.
Adsorption mostly uses the physical process. Here, the particles are removed from the water as they stick to the surface of the material in the filter. These types of filters are made with granulated or powdered carbon. They are also the most common types of filters found in the market which also comes in various forms, including pitchers and faucet-mounted systems. They effectively reduce the most typical types of compounds that can be found in municipal water: chlorine byproducts and dissolved volatile organic chemicals like pesticides and herbicides. They generally work well to reduce bad odors and tastes.
Softeners/Ion Exchange Units:
Some water purifier units use ion exchange to reduce the hard metals and lead from the water. When the impure water passes through an ion exchange unit, the hard metals are replaced with sodium ions, leaving the water “softer.” This type of technology is used in combination with adsorptive or reverse-osmosis filters.
Ultraviolet (UV) Treatment:
Few water purifiers also use UV treatment to kill germs. This type of treatment is certified by the National Sanitation Foundation International that can help to reduce bacteria.
In the process of water distillation, the water turns into steam which is then collected to its liquid form. When the water evaporates, the contaminants are left behind. Distillation is very effective while removing most minerals and bacteria. However, some units of distillation do not remove VOCs.
In reverse osmosis, the water is forced through a membrane which filters out all the molecules that are physically larger than the water molecules. Although RO works well in reducing minerals, it is not as effective for chlorine or volatile organic compounds (VOCs) which are the major concerns with using municipal tap water.
Stages of RO systems
The system of RO water filtration is the focal point of reverse osmosis. It also includes other types of filtration as the RO system is made up of 3, 4, or 5 stages of filtration.
Every RO water system contains sediment and carbon filters in addition to RO membrane. These filters are known as either pre-filters or post-filters that are depending on whether the water passes through them before or after.
