Water Purification Technology Explained

It is common knowledge that the water available in nature has various contaminants like chemical, physical, and microbiological. It makes it unfit for human consumption. So, it is necessary to have a safe and pure drinking water for our existence.

What is Water Purification?

Do you know water purification is a complex process? It is based on the level and nature of contaminants present in the water. Water purification is a method where contaminated, dirty, and suspicious water is processed, which is suitable for reusing and drinking. Certain contaminants will lead to health hazards, and others will modify the taste, smell, and appearance. 

Water Purification Techniques

Some of the major water purification techniques are – 

1. Activated Carbon

Activated carbon has small pores whose size ranges from 500-1000 nm. The surface area is roughly 1000 square meters per gram. Here the nature of this particular surface will absorb all kinds of impurities from the water.

The activated carbon’s huge surface area means organic compounds will absorb to the surface using polar, ionic, and Van der Waals forces. Frankly, activated carbon is used along with other water purification technologies. It helps in removing all kinds of chlorine and chloramine.

2. Electrodeionization (EDI)

EDI is an electronic run water treatment that uses electricity, resin and ion exchange for removing all kinds of ionized species from water. The whole combination of the ion-exchange membranes and ion-exchange resins helps remove all the ionic impurities and convert them into waste. 

3. Ion Exchange

As the name suggests, this is the exchange of ions among ionized species present in the water and the ion exchangers like OH- and H+ ions. It is a reversible procedure, and the column would be regenerated through the washing of the excess ions. 

4. PureSure

PureSure is one of the unique purification techs having a double purification pack and a monitoring system. It helps in providing accurate results through an uninterrupted workflow. By this method, you are guaranteed to get the best and optimum water quality, extended consumable service life, and advanced warning of the consumable change. 

5. Reverse Osmosis

One of the cost-effective methods of removing all kinds of impurities from water is reverse osmosis. Here this is done using a semi-permeable membrane. 

6. Sub-Micron Filtration

This method works in the same way as the sieve. Here it builds a physical barrier based on the pore size for the passage of the particles present in the purified water equipment. The membrane filters with a pore size of 1 to 10nm remove particles as small as the protein macromolecules. 

7. Ultraviolet

The ultraviolet method is used to inactivate the microorganisms by interruption of nucleic acids and interjecting their DNA, thereby preventing effective replication. UV lights used in the laboratory water purification systems are low pressured mercury lamps.
