Water purification is a process by which undesired chemical compounds, organic and inorganic materials, and biological pollutants are removed from the water. One prime purpose of water purification is to provide clean drinking water.Water purification also meets the needs of medical, pharmacological, chemical, and industrial claims for clean and potable water.
The purification exercise moderates the concentration of contaminants such as adjourned particles, parasites, bacteria, algae, viruses, and fungi.
History of Water Treatment
Historical suggestion advocates that water treatment was recognized and practiced by ancient societies. Elementary treatments to water purification have been recognized in Greek and Sanskrit writings and Egyptians used alum for precipitation as early as 1500 BCE.
Water Treatment In Modern Time
In modern times, the quality of water that must be purified is typically set by government agencies. Since it is impeccable to examine water based on appearance, numerous processes, such as physical, chemical, or biological analyses, have been developed to test contamination levels. Level of organic and inorganic chemicals, such as chloride, copper, manganese, sulfates, and zinc, microbial pathogens, radioactive materials, and dissolved and suspended solids, as well as pH, odor, color, and taste, are some common constraints analyzed to assess water quality and contamination heights.
Not everyone in the world has access to safe drinking water. According to a 2017 report by the United Nations (UN) World Health Organization (WHO), 2.1 billion people absence access to a safe and reliable drinking water supply at home.
General household methods such as boiling water or using an activated carbon filter can remove some water impurities, but these process does not remove more dangerous contaminants. For the treatment from hazardous pollutants, the Aquafresh RO system is taken into account.
Various minerals are found naturally in water and are significant for the human body, but an intense amount of it can cause multiple diseases. A good water purifier eliminates the excess salts, suspended elements, and microbes, and holds 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 essential standards.
Things You Need To Know About Water Purifiers
Water purifiers comprise different types of filters to make the water contaminant-free and make it consumable with maintaining its essential minerals. Aquafresh RO can contain all the vital minerals during the purification process. It has many variants like one stage filter, two-stage filter, and three-stage filter are also there for you. If you want to opt a purifier that has less maintenance and maximum benefits, then go for Aquafresh RO purifier.
1. Reverse Osmosis filters (RO)
Reverse Osmosis (RO) system provides a multi-stage filtration of water by uniting active carbon and also particle filtration. Here, the tap water is passed through a membrane that has minute-sized pores and this sleepout minerals and microorganisms in water. The pollutants collected are then flushed out through an outlet pipe.
An Aquafresh water purifier advances the taste of water but, it is tough to say that the water will be 100% safe as at times due to holes as it is considered as some manufacturing mistakes in the filter, some bacteria can get through the filter. RO filters are suggested for places where the problem with the water is its high content of dissolved minerals.
The dark side in an RO purifier is that there are odds that the membranes in these filters drain out some of the essential minerals too. Also, it requires a continuous water supply to work and can be fixed to only one water tap.
2. Ultra Violet filters (UV)
UV light (low-level radiation) is passed on the water to destroy bacteria and other microbes by attacking the DNA in cells. These filters eradicate pesticides up to 98%. This filter is operative in removing all types of pathogens but is not effective for eliminating chemicals, taste, suspended particles, color, or smell.
3. Biosand filter
It has a concrete or plastic box that is occupied with layers of sand and gravel, which eradicate pathogens (microorganisms in water) and suspended solids from polluted water.
Water (should be free from hazardous chemicals since the filter cannot remove most of the chemicals) is discharged into the top of the filter and collected in a safe storage container. Bacteria and other microorganisms breed in the topmost layer of sand, which is called the Biolayer. The microorganisms at the biolayer eat away the pathogens in the water, thereby improving the water quality.
Ion exchange resins filters: Water is passed through resins that soften water by gripping the minerals present. These filters can soften the water by absorbing the salts present and can also entirely de-mineralize the water.
4. Ceramic filters
These are deep cylinders that are generally made from mud mixed with a flammable material like sawdust or coffee husks.
These drain out bacteria in the water over the small-sized pores in them. It removes chlorine and E.coli bacteria up to 99%. Its safe storage capacity prevents water to get contaminated again.
What To Look Before Buying A Water Filter
- Is the product is accredited by a prominent institution such as NSF, WQA, and FDA?
- How regularly the sediment filter/membrane needs to be cleaned or replaced?
- What is the warranty on the components of the machine and how many free facilities does the firm offer?
Which One To Buy?
There are numerous brands of water purifiers in the market like – Tata Swach, Eureka Forbes, Kent, Pureit, etc. Each of these products varies in cost, type of filter they use and the method of purification. Most water purifiers today combine two-three techniques.
For instance, Eureka Forbes’ Aquaguard Protect Plus combines the advantages of a Reverse Osmosis purifier and Ultra Violet sterilization. Hindustan Unilever’s Pureit Marvella UV offers the benefit of UV sterilization as well as offers filtration through an activated charcoal filter. An innovative model of water purifiers that offer a mixture of technologies will cost anywhere between Rs 8500 and Rs 16000.
Water purifiers have become an essential part of every kitchen now, and manufacturers of these products are challenging to garner market share. The advantage for a shopper here is that she/he can expect decent discounts in these products, especially when purchasing during a festive season.
