Water purifier contains different types of filters used in our homes. Pure, clean and safe drinking water isn’t available easily these days. Growing population, industrial development, and environmental degradation are all causes for this. Given this situation, it becomes even more important for us to be aware of purification techniques and the available water purifiers in the market to ensure that our drinking water is of good quality.
A lot of minerals are found naturally in water and are important for the human body but consuming an excessive amount of it can cause many diseases. A good water purifier removes the excess salts, suspended particles and microbes, and retains its essential vitamins and minerals. With so many manufacturers in the water purification industry these days, it is difficult to know which is good, which isn’t and which meets the necessary standards.
Both water filters and water purifiers work on the same mechanical principle. They first suck up raw water which is contaminated, filter out impurities ranging from sediments to micro-organisms and then dispense clean water. However, there is one big difference between the two – a purifier can remove viruses and bacteria that filters cannot remove. Some purifiers use chemicals and others use an electrostatic charge to kill or capture viruses.
One of the earliest methods of water purifier was to add chlorine in water. Chlorine releases hydrochloric acid, which reacts with the microorganisms and kills them. However, due to its negative effect on health as well as its ineffectiveness to kill certain types of protozoa, this technique lost popularity paving the way for other purifying techniques.
Active Carbon filter: This kind of filter is used to purify soluble gases such as chlorine, carbon monoxide, nitrogen, ammonia and organic material like dead algae, leaves or any other dead thing washed into a water body. The porous nature of the carbon (charcoal) helps to absorb chlorine and pollutants such as pesticides. Generally, household carbon filters come with a lining of activated silver that kills bacteria.
