Amrit Technology For Removal Of Arsenic And Metal Ions From Water

Last Updated16/12/2023

Recently, the IIT-Madras developed a technology called AMRIT (Arsenic and Metal Removal by Indian Technology) technology.

IIT-Madras has developed the 'AMRIT' technology for the removal of Arsenic and Metal ions from water.
It uses nano-scale iron oxy-hydroxide to selectively remove arsenic and metal ions when water is passed through it.
This technology is recommended for both domestic and community use.
It has been recommended by the erstwhile ‘Standing Committee’ of the Department of Drinking Water and Sanitation for the examination of the best technologies concerning water and sanitation.

It is a natural component of the earth’s crust and is widely distributed throughout the environment in the air, water and land.
It is highly toxic in its inorganic form.
In its most stable elemental state, arsenic is a steel-grey, brittle solid with low thermal and electrical conductivity.
Although some forms of elemental arsenic are metal-like, the element is best classified as a nonmetal.
It has been recognized as a toxic element and is considered a human health hazard.
Long-term intake of arsenic contaminated water leads to arsenic poisoning or arsenicosis, with cancer of skin, bladder, kidney or lung or diseases of skin.
The World Health Organisation’s provisional guideline value for arsenic in drinking water is 0.01 mg/l.
Permissible limit of arsenic in India in absence of an alternative source is 0.05 mg/l.
