About Amrit Technology:
- It is developed for the removal of Arsenic and Metal ions from water.
- The technology uses nano-scale iron oxy-hydroxide, which selectively removes arsenic when water is passed through it.
- This water purifier has been developed for both domestic as well as community levels.
- Also, the technology 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.
Key points about Arsenic:
- 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.
- Properties:
- 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.
- World Health Organisation’s provisional guideline value for arsenic in drinking water - 0.01 mg/l (10 μg/l).
- Permissible limit of arsenic in India in absence of an alternative source - 0.05 mg/l (50 μg/l).
