Features of a Water Purifier

As essential as water is to our survival, many problems can arise when we consume contaminated water. There are so many water sources which include wells, reservoirs, rivers and even rain water. These water sources though natural, have been found to be heavily contaminated and can cause many ailments if consumed as is. Tap water is widely believed to be free from contaminants but this also has been found to be false. Water purifiers have become increasingly necessary to ensure we have safe drinking water for consumption.

Water purifiers come in different types and brands; each using a filtration technique or a combination of two or more techniques and each claiming to be the leader in the water purification arena. It is very important to know the filtration techniques each brand or product provides and how effective it is for your water needs before going ahead to purchase the unit.

Water purifiers can be classified into the following types;

Distillation: In a water purifier that is based on the distillation principle, water is brought to its boiling point and the vapors produced are collected to give you purified drinking water. Distillation removes contaminants, sediments and microorganisms, leaving you with pure and safe drinking water. This process can be slow, time consuming and produces an output of about 1/10th of the total input.

Activated Carbon: Activated carbon is widely used to filter water. When the water flows through the carbon surface, the contaminants adhere to the activated carbon, giving you clean drinking water. This process does not kill the microorganisms in the water so it is not perfect, so to speak.

Reverse Osmosis: Reverse Osmosis is one of the most common and widely used technology used in water purifiers today. In a reverse osmosis water purifier, water is forced through a semi-permeable membrane so that only water molecules will pass through, trapping sediments and contaminants on the other side of the membrane.

Ultra Violet: In water purifiers with ultra violet technology, UV bulbs emit ultraviolet radiation that is capable of killing harmful and disease-causing bacteria in the water. This system alone only kills the bacteria but their bodies remain in the water.

No one filtration technique is 100% capable of purifying your water and making it completely safe for drinking. Many manufacturers realize this so it is not strange to find a water purifier with a combination of two or more filtration techniques in one unit. The ideal combination is the reverse osmosis and the UV purification system as explained on bestwaterpurifierinindia.in. The UV radiation will kill the bacteria and the semipermeable membrane of the reverse osmosis system will filter out the bodies of the dead bacteria out of the water.
