Water Purifier: The Best Way To Say No To The Water Contamination

Water Purifier: The Best Way To Say No To The Water Contamination


It is hard to find pure, clean, and safe drinking water in today’s world due to industrial development, growing population, and environmental degradation. Now it is vital for all to be aware of water purification techniques and available water purifiers to ensure that our drinking water is safe for us. Many minerals found in the water are essential for the human body. But consuming minerals in excess amount can cause us many diseases. A proper purifier can remove excess salts, and it removes terrible particles and microbes, and keep its essential vitamins and minerals.

Water purifiers and water filters both work on the same mechanical principle. They first suck up unclean water then filter out impurities and then supply clean water. However, filters cannot remove viruses and bacteria, but purifiers can. Purifiers use chemicals and electrostatic charge to kill germs.

Evolution of purification techniques

Adding chlorine into water is one of the oldest technique to clean the water. It releases hydrochloric acid, which kills the micro-organisms. However, sometimes it is unable to kill some protozoa, and it has some adverse impacts on health also that’s why it is not so popular.

Six different types are available

Active Carbon filter: The active carbon filter purify water-soluble gases such as carbon monoxide, chlorine,  ammonia, nitrogen, and organic material like dead algae, leaves, or any other dead things. Carbon (charcoal) absorbs chlorine and pollutants such as pesticides.

Bio-sand filter: It is a type of box which filled with layers of gravel and sand, which removes pathogens and dirty solids from contaminated water. At the top of the filter, the impure water gets poured, and it passes through all the layers which take away pathogens, suspended particles and improve water quality.

Reverse Osmosis Filters: Reverse Osmosis (RO) is a multi-layered system of water filtration by combining active carbon and particle filtration. Here, the tap water is passed through a membrane (a polymer film) that has very small-sized holes, and this eliminates minerals and micro-organisms from water. The impurities are thrown out through an outlet pipe. It improves the taste of water but, but we can’t say it is 100% safe. RO filters are used primarily when the problem with the water is its high content of dissolved minerals. It requires a fixed tap and continuous water supply.

Ultra Violet (UV) filters: The Ultra Violet light (minimum level radiation) is passed through the water to eliminate the bacteria and other microbes by attacking the DNA in cells. This filter removes 99% of pesticides. It is not so useful for removing suspended particles, chemicals, taste, smell, or color, but it helps clear all types of pathogens.

Ceramic filters: This is made from clay mixed with a combustible material like sawdust, rice husks or coffee husks and shapes are like hollow cylinders.

These filters remove bacteria from the water through the small-sized pores in them. It removes chlorine and bacteria up to 99%.

Ion exchange resins filters: It softens water by absorbing the minerals present in the water, and it passes through resins. It can soften the water by sucking up the salts present and can also wholly de-mineralize the water.

Things to keep in mind while purchasing purifiers

Step 1:  Get a laboratory water analysis for your drinking water. It includes general water test, which finds out total coliform, bacteria, nitrate, pH, Total Dissolved Solids (TDS), fluoride, organic carbon contaminants (pesticides, industrial pollution, etc.). A mechanic in your area who is expert in the job of water purifier repair can be a good source of primary information that you’re looking for. The report will decide whether you want a filter or a purifier.

Step 2: Now, you’ve to decide whether you want a water purifier for the drinking water tap or the entire water system of the house.

Step 3: Shortlist some brands from the market. Check the product’s standard. Acclaimed institutions such as (NSF), (WQA), (FDA), etc., give accreditation to water purifiers.

Step 4: The best quality of membranes and filters are expensive. You can take the help of online search. And make sure to consider the cost ofRO repair.

Step 5: Finally, when you go inside a shop to buy the product, you can ask the same questions as discussed above.

Which one to buy?

There are a lot of brands available in the market about which you can take the help of online platforms to check it’s price, compare it with other products or brands, test features, see the customer’s rating, maintenance cost, etc. Once you’re fully satisfied with your searches, you can take your step ahead to purchase the suitable RO for your use.
