Water purification can be carried out in different ways to suit different purposes. While it could be carried out for industrial or medical applications as well, the most common purpose for purification is to make the water fit to drink. The methods used for each of these vary as per the desired results.
When we talk about water for drinking purposes, the WHO guidelines specify a range for acceptable concentration of total dissolved solids. This has to be kept in mind because the human body requires some of these dissolved solids for the effective functioning of the different bodily systems. A water purifier is designed to follow these guidelines. So, yes, they do provide 100% safe drinking water.
The Different Contaminants and Their Removal
The water supplied to different parts of the country, cities and even specific localities can be different in their composition. As per the latest guidelines, all water must be tested, even spring water, to confirm its potability. If it does not meet the requirements, appropriate methods of purification must be applied.
There are four basic kinds of impurities present in the water. While many are harmless, some can be harmful if present in the water. These are the ones that need to be removed.
- Physical Impurities
These include impurities like soil sediments, sand, silt, rust and heavy metals. These are mostly present due to natural causes, are generally larger in size, make the water look dirty and are clearly visible. These particles can be removed through simple methods like sediment filtration and gravity-based filtration.
- Organic and Inorganic Chemical Impurities
These impurities mostly get added to the water due to the actions of humans. These could be resulting from the various chemicals such as pesticides and chemical fertilisers used when trying to make life better. These, when ingested beyond a limit, can be extremely harmful. For such impurities, advanced systems like RO purification may be required as it can remove up to 99% of the minerals from the water.
- Biological Impurities
Biological impurities such as bacteria, viruses and other microorganisms could be naturally existing in the water, but the higher proportions are heavily impacted due to human actions. These, if not removed, could lead to serious illnesses and water-borne diseases. These can be effectively killed using UV water purifier. Ultra-filtration helps to remove all microscopic contaminants effectively from the water.
- Other Impurities
Apart from these, the water could have a brackish taste due to the presence of certain chemicals like chlorine. This can effectively be improved by using activated carbon filtration. This can also reduce the concentration of several chemicals in the water.
- Radio-logical Waste
These include substances like uranium and can be very harmful for health if ingested. These can be removed using a combination of the various water purification methods used above, such as RO, carbon filters and ion exchange.
