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
Beyond point-of-use purifiers, improving source water quality is essential. Many municipalities and industries now deploy wastewater treatment and reuse systems to reduce dissolved solids, organics, and microbial loads before water reaches the tap. Solutions from Bioprocess H2O combine high-performance filtration and biological processes to help produce high-quality reclaimed water, conserve supplies, and lessen the burden on RO and UV units in homes and clinics. Strengthening both upstream treatment and household purification offers a more reliable path to safer, better-tasting water.
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?
