What Does a Water Purifier Do?

With the increase in pollution and the spread of waterborne diseases, water purifiers today are a must for every family. A water purifier guarantees clean water. There are many ways to purify water and reverse osmosis is one of the most advanced and widely used technologies today.

Water filters and water purifiers filter the sediment contaminants and remove the microorganisms, to offer you clean drinking water. However, there is a big difference between the two: an air purifier can remove viruses and bacteria that filters cannot. Some cleaning products use chemicals and others use an electrostatic charge to kill or trap viruses.

Types of Water Purification Technologies

UV water purifier

UV water purifiers are ideal for municipal water purification. It purifies water using a 3-step cleaning process. The first step is to filter suspended matter such as dust and mud. In the second step, all organic contaminants, bad smells and tastes, lead, pesticides and volatile organic compounds are absorbed and removed. The third step then deactivates viruses, bacteria, protozoa and other pathogenic microorganisms.

UV technology uses ultraviolet rays to purify water and make it as pure as if it were boiled for 20 minutes. In fact, it eliminates the possibility of recontamination when cooling or handling water during manual cooking.

UV cleaning ensures that no chemicals are used during the process and that all the important minerals your body needs to stay healthy are preserved.

RO water purifiers

This technology is ideal for areas with hard water, which contains high levels of fully dissolved salts (TDS). In reverse osmosis or RO technology, water passes through a thin-film composite membrane at high pressure. This will reduce the amount of salts and minerals dissolved in the water by about 90% and bring them back to healthy and acceptable levels. Hard water consists of heavy minerals and salts like iron, arsenic, mercury, fluorine, lead, and nitrates, etc.

RO technology removes all physical, chemical or biological contaminants and protects you from waterborne diseases. Several houses are exposed to water from different water sources. At such times, it is best to use water purifiers that use a combination of RO and UV technology.

Reverse osmosis

The reverse osmosis system includes a simple water filter mechanism. The filtration system involves passing water or other solvents through a semipermeable membrane. The membrane blocks dissolved solutes that contaminate the water. The process filters out all kinds of contaminants such as ions, pesticides, microorganisms and other chemicals from the water. This filtration process is one of the most effective methods of water purification. Desalination is the process of removing salt from seawater. Many water treatment plants have started using this reverse osmosis technique to solve many water-related problems.

There are several components involved in a reverse osmosis system. The functions of the components that are an integral part of the RO system are as follows:


Water flows through the cold water line valve and then it is passed through the RO pre-filter. Most pre filters are carbon and sediment filters. They remove large particles like chlorine, dirt, and other sediments to protect the RO membranes from damage.

RO membrane

The RO membrane is an important part of the system. The membrane helps remove contaminants from the water. After this cleaning step, the water enters the storage tank.

Storage tank

As its name suggests, this tank purifies treated water. The storage capacity of air purifiers varies, so it is necessary to check the usage before making a final decision.

Filter messages

Before the water is stored in a tank and comes out of the RO valve, it enters a final carbon filter. The purpose of carbon filters is to remove bad odors and improve the taste of water, so that it tastes good and contains no smell.

Drain line

The drain line is used to remove dirt and other impurities. UV disinfection

A UV lamp is generally used for UV disinfection. The UV lamp provides pure and safe drinking water. The UV light used in this procedure is high power UV, also known as UV-C or UV germicide. UV-C rays enter the body of pathogens to deactivate them. Ultraviolet rays alter the DNA of pathogens to prevent their multiplication and growth. Ultraviolet rays can kill almost 99.9% of microorganisms present in the water.

Unlike chemical disinfection, harmful microorganisms cannot develop an immune mechanism against ultraviolet light (source: Water Tiger). The pretreatment process maximizes the effectiveness of the treatment. During the pre-treatment phase, the water passes through sediment filters and carbon filters. Sediment filters help remove sludge, while carbon filters help remove organic contaminants from the water.


The UF process uses hydrostatic pressure to force water pass through a semipermeable membrane. that helps remove bacteria and various types of microorganisms, as well as bad odors, from the water.

The ultrafiltration system helps remove colloids, bacteria, pathogens and other molecules larger than the pore size of the semi-permeable membrane.
