Different Types of Water Purifier


I bet you must be thinking of buying a water purifier. But hold on, there is a more important thing for you to do before making the purchase. And that is thorough research on different types of water purification systems.

Not all water filters work by the same principle. There are different methods and procedures used in water filters to carry out the purification process. Each purification process is used to eliminate different kinds of contaminants and impurities. The decision of choosing a water purifier depends upon the sediments and contaminants present in your water resources. Every type of filtration process has its own advantages and disadvantages.

If you want to know which type of water filtration system would fit your requirements, then keep reading this article till the end. We have discussed different types of water purifiers along with their uses in different fields.

According to this article biomadam.com/difference-between-hard-water-and-soft-water, consuming hard water may cause various health issues. This is another important reason you should think about installing any purifier system.

1: Reverse osmosis (RO) Water Purifier

Reverse osmosis (RO) water purifier purifies the water by using semipermeable membrane or multiple filtrations systems. It involves the passage of water through the semi-permeable membrane by a water pump that pressurizes the water flow into the semi-permeable membrane.

These membranes block the contaminants and remove contaminants based on their size and shape. Different parts of RO play role in the purification of water. One of them is Pre- Filters that use carbon and sediments filter are used to remove dirt, chlorine from the water. It is the most effective method for purification used in homes and industrial units

2: Gravity based Water Purifiers

In this type of water, purifier water purification is based on the force of gravity. It purifies water by using activated carbon filters that have small carbon granules that absorb water impurities. It consists of two chambers, an upper and lower chamber.

As the water moves from the upper chamber to lower through the pressure the impurities of water stick with the filter (carbon surface). Some gravity filters use ultrafiltration filters or membrane which has 0.1μ pore size. This is used to remove the bacteria, cyst from the water.

3: Ultraviolet Water Purifier

An ultraviolet water purifier is used to remove microorganisms from the water. This purifier has the ability to kill 99.9% of microorganisms by using ultraviolet rays.  A UV lamp that is covered by the glass quartz sleeve emits UV rays. These rays are germicidal and have the capacity to penetrate the pathogen. These rays kill the bacteria or viruses by damaging their DNA. Water purification via this purifier needs pretreatment of water with sediment filters, carbon filters to remove impurities in water.

4: Ultra Filtration (UF) Water Purifier

Ultra-Filtration is similar to a reverse osmosis purifier. It uses semipermeable membranes to filter the water. These membranes have a pore size of 0.005 to 0.1μ. When the water passes through these membranes via hydrostatic force; suspended particles in water stick in the membranes. It is used to remove colloidal particles such as bacteria and viruses from the water.

5: Activated Carbon Water Purifier

The activated carbon water purifier is used to remove microorganisms, chemicals, and organic compounds in the water that make its bad odor and taste. This uses activated carbon filters that contain pores and have a large surface area and use the process of adsorption to remove the contaminants from the water.

The contaminants stick to the pores of filters that contain granular activated carbon (GAC granular activated carbon (GAC) that make an easy flow of water through it. Some carbon filter consists of carbon block filters that give more surface area than GAC. Inside the carbon filter is either Bituminous coal, wood-based media, or Coconut shell media is present.
