A)
IISC Bangalore
B)
Tezpur University
C)
Bangalore University
D)
Jawaharlal Nehru Centre For Advanced Scientific Research

Correct Answer : Option (B) - Tezpur University


Researchers at Assam's Tezpur University have developed a simple and cost-effective filtration system - Arsiron Nilogon - that may help reduce the health burden caused by arsenic and iron contaminated groundwater. The system filters out 99.9% of the arsenic contamination from the groundwater to make it suitable for drinking. The chemicals used in the filtration process are cooking soda for pH conditioning, potassium permanganate for supplying oxygen and ferric chloride for providing solid iron oxide adsorbents of arsenic. The method can remove arsenic even to below 2 ppb (parts per billion) level while the World Health Organization (WHO) has set 10 ppb as the standard level. According to theWHO, arsenic is a natural component of the Earth's crust and is widely distributed throughout the environment -- in air, water and land. However, it is highly toxic in its inorganic form.
