How to remove arsenic, chlorine and bacteria from water?
Arsenic is a metal that enters water by the breakdown of minerals and ores. In some places, arsenic concentrations in groundwater are higher due to erosion from arsenic-rich rocks, and in other areas, industrial effluents also contribute to arsenic concentrations. Arsenic is released into the environment through the combustion of fossil fuels, through diffuse air deposition.
Finally, although arsenic can be present in the environment in a variety of forms, trivalent arsenite or pentavalent arsenate are the most common. Seafood is a rich source of organic arsenic species, which are far less hazardous to health and are easily excreted by the body. Arsenic poses the greatest risk to human health through drinking water. Workplace exposure as well as emissions from mining and industry could be significant.
The World Health Organization (WHO) standards state that the maximum allowed content, of arsenic in drinking water is 10 parts per billion.
Technologies for removal of arsenic from water
The following basic procedures are used by all arsenic removal technologies:
· Reduced Oxidation: The reactions that change the chemical forms of arsenic by reducing or oxidising it.
· Process of precipitation: It causes dissolved arsenic to transform into a solid mineral, with a low solubility that may be filtered out.
· Adsorption through ion exchange: It includes the reversible displacement of a dissolved ion, by an ion that has been adsorbed onto a solid surface.
· Filters: Synthetic membranes can function as molecular filters to remove dissolved arsenic, along with other dissolved solids because they are permeable to some dissolved compounds, while excluding others.
· Activated Alumina: AA Adsorption is a physical/chemical process whereby accessible adsorption sites, on an oxide surface remove ions in solution. Fluoride, arsenic, selenium, silica, and organic natural substances are among the contaminants, which can be removed by AA, which is usually utilized in packed beds.
· Reverse Osmosis: Arsenic removal has been successfully accomplished using reverse osmosis.
Removal of bacteria from water
Ultra Violet disinfection is one of the four procedures that the US FDA has approved for the removal of bacteria. It is one of the safest filtration systems available.It will disinfect filtered water at regular flow rate.
By interfering with the DNA and RNA involved in the reproductive cycles of the organisms, bacteria, viruses, and other microorganisms are eliminated.
Units that disinfect with UV
Numerous health issues might be brought on by waterborne microbes. The natural approach to disinfect water for use in industry or at home, is with an ultraviolet system.
Water is disinfected using UV light systems, which reach the hazardous organisms and kill it. You might be able to use Netsol’s Reverse Osmosis system to get rid of additional impurities, from drinking water.
Removal of chlorine from water
Does the chlorine taste or smell in your drinking water have an unpleasant odour that is not brought on by iron or bacteria? Does it taste like "Swimming Pool Water," have a "Bitter," "Musty," "Earthy," or have a Slight to Moderate Sulphur "Rotten Egg" smell? Does it taste and smell like chemicals, or does it taste and smell like strong chlorine or chloramines, which are typically a mixture of chlorine and ammonia.
The media reaction & filtration process is effective at removing unpleasant tastes, smells, and pollutants, such chloramines, chlorine, and mild to moderate sulphur.
Regular backwashing by these media filters flushes pollutants, tastes, and odours down the drain. Many homeowners send the backwash water directly onto their plants or trees, since the backwash is harmless for the environment, if you are notusing any salt or other chemicals.
