Different Types of Methods Used for Water Purification

The water from any type of source is purified or disinfected through a single method or any combination of methods that have been given below:


Earlier than the primary filtration takes place, the water is passed across a pre-filter. Every single pre-filter's design is intended in such a way that it helps in getting rid of the silt, dust, and sediments out of the supplied water. The pre-filters are graded in terms of the size of the particles (in microns), it might be able to remove.

  • Enhances the competence of the primary filter (UV/RO)
  • Keeps the primary filter away from any sort of damage
  • Helps in improving the life expectancy of the water purifier’s main filter

Sediment Filtration

It makes use of the gravity principle for filtering the water. Whilst the water moves across the installed filter, the suspended atoms are confined over the filter’s surface and are not allowed to go ahead.

  • Utilized for pre-filtration in the RO water purifiers
  • Necessitates consistent replacement of the filter

Activated Carbon Filtration

The blocks or granules of carbon are charged through the molecules of silver.  Whilst the water moves through the Activated Carbon Filter, every single impurity in the water gets stuck inside the apertures of the filter.

  • The size of the particle that the Activated carbon Filter might be able to trap is stated inside the description of the filter.
  • This type of filter is also utilized for the pre-filtration process

Reverse Osmosis (RO)

Working: In this water purification technique, the pressure of water powers the water molecules across a Semi-Permeable Membrane (SPM), which comprises exceptionally small pores of just a few microns in size. Several membranes are moved together to take the shape of a cylinder. This is going to permit all the solutes that are smaller in comparison to the size of the pores on the membrane to move through and the bigger ones get trapped on the surface of the membrane.

  • The RO Water Purification doesn’t require electricity
  • RO Water Purification isn’t effective when the water pressure is low
  • These are unable to treat the biologically unsafe water.

Ultraviolet Filtration (UV)

Working: It is a method used for disinfection. The water moves inside a cylindrical compartment, which comes with a UV lamp. When the pathogens are provided exposure to the UV rays at every side, they are either killed or deactivated.

  • This is going to eliminate those dangerous viruses, bacteria, and other microorganisms
  • The consumption of energy is below even the 60W bulb

Ultra Filtration (UF)

Working: This is a type of membrane filtration, which makes use of the size exclusion principle. Solely the water and the solutes with really low molecular weight are going to be allowed to move through.

  • This is commonly utilized as a Post/Pre-filtration method.
  • In the ultramodern purifiers, Nano-filtration, as well as microfiltration, is being utilized for pre-filtering the supplied water.

To get the drinking water of the finest quality, the contemporary purifiers filter the water employing a few stages in which an arrangement of diverse filtration techniques is implemented.

Water Purifier Buyer’s Guide

Main Components of RO Water Purifier

Sediment Pre-filter

In the preliminary stage of the cleansing of water, it is filtered utilizing a pre-sediment filter. It not only removes fine and rough particulate scums/dirt but also recuperates the life of the RO/UF membrane ensuing in a lower cost of upkeep. If the cleaner does not include this as a standard feature then it can be added as well.

Activated Carbon Pre-filter

The activated carbon pre-filter eliminates chlorine and organic layers like harmful pesticides from the water. Activated carbon pre-filter also grips bad odor and taste-causing biological mixtures from the water.

RO/UF membranes

 Water is nurtured into the RO membrane at high-pressure by in-built water propels. RO membrane removes the firmness, softened salts, pesticides and substantial metals like lead, arsenic, and mercury. It also removes microbial contaminants like viruses, bacteria, protozoa, and cysts. The UF membrane also works like the RO membrane but it does not confiscate the liquefied solids. Some sterilizers use both RO and a UF membrane, the output water from both the membranes is proclaimed to control the TDS level of cleansed water.

TDS controller

 TDS controller is recycled to switch the TDS level of the output water. RO procedure not only eliminates bad scums but also eradicates vital minerals like Calcium & Magnesium. TDS controller recollects passable amounts of indispensable minerals in the purified water by regulating the ratio of water from RO membrane (low TDS) and UF membrane (normal TDS) in the final mix.

UV Filter 

UV filter uses a high power UV bulb to kill or deactivate any virus, bacteria, and fleas to bring safe water.

Carbon Post-filter

 The Carbon post-filter acts as a polisher and improves the taste of cleansed water. It also eliminates any lewd odor from water.

Storage Tank

 This tank stores the sanitized water for later use. Ensure the storage tank is made of food-grade, non-toxic substances. Some of the high-end water sterilizers now come with stainless steel water storing tank. You must check the capacity of the tank.

Why we need water purifiers and how they help 

Drinking tap water is not always the best option. It is not because the water is not potable, much less, but because the water can have an excess of salts such as lime. Our kidneys can be affected over the years with this excess of lime and, therefore, today we bring everything you need to know about the water purifier. We are going to tell you all the advantages that water purifiers have and how they work.

What is it and what is it for

In the water not only excess salt come but some microorganisms and bacteria that can cause some health problems. These impurities can be cleaned with a water purifier. It is a device that is responsible for cleaning the water that comes out of the tap so that it is free of impurities when we go to drink it.

Although the water is drinkable, we can observe the existence of some harmful substances in it. For all this is the water purifier. All we can find nowadays have advanced technologies that are based on the use of mechanical activated carbon filters and some separation membranes. There are also more advanced ones that use microfiltration to perform reverse osmosis. These types are the most sophisticated.

Drinking water can be softened through these purification systems. In general, they should be eliminated during the operation of the water system in the supply companies, but 100% cannot always be guaranteed free of correct microbiological, chemical and physical agents.

These purifiers are placed directly on the tap or in a container in the kitchen. These purifiers consist of various filters capable of cleaning the water of microorganisms and bacteria to eliminate all dirt or unwanted substance. Therefore it is very useful to place in places where the water quality is somewhat lower. This way we will be ensuring that we drink quality water.

There are different types according to their complexity. The most complete are those that require installations throughout the house and the simplest only the filter next to the tap. Both types serve for the same, but at different levels of effectiveness.

Advantage of water purifiers

 Among the advantages that we find when it comes to obtaining a purifier we have:

  • Drink pure water. This is especially important in cities where water quality is not very good. To ensure that we are always drinking pure water, we should check the filters every so often and change them regularly. If this is not done in time, bacterial colonies will be stored.
  • It reduces the risk of diseases. By not drinking water with bacteria and other microorganisms reduce the likelihood of getting sick by drinking water in poor condition.
  • Pregnant women and children will drink more healthily. In the stage of pregnancy and when we are small it is important to take good care of what we eat. Our body is not so efficient eliminating harmful bacteria from the body, so you have to give it that little help.
  • They are installed easily. Unless we need large-scale water purifiers throughout the house, common filters are easier to install. Neither do they need great maintenance except for the change of filter every so often.
  • You save money and effort. In the medium and long term, it is more comfortable and thrifty since it is cheaper than buying bottled water. You have to make an initial investment, but in the long run, you'll be saving, since bottled water is more expensive.
    • Improves the taste of water for those waters that taste bad, this filter eliminates those flavors.
  • Aids to the environment If you use these filters and avoid bottled water, we will be reducing the emissions of plastics to the environment.
  • You can choose the purifier that works best for you. There are different types and each one adjusts better or worse to the demand.

Maintenance and installation of a water purifier

 As we have seen, the good use of these filters is as necessary as taking water in good condition. Therefore, we will discuss the main maintenance needs of these purifiers.

The main maintenance is summarized in the cartridge change when needed. To do this, we must follow the manufacturer's instructions, although it is possible that depending on the use we are giving, we have to change it more frequently. This maintenance is minuscule compared to all the advantages offered by this device.

To install them we only need to cut the water flow and open the taps to let the wastewater run. Then we will connect the adapter in the tap and the purifier container. The container can be attached and placed in different ways. These systems are coupling and use, so we will not need the help of any plumber.
