On the event of World Water Day, the main target was on attaining Sustainable Improvement Objective (SDG) 6 and water/ sanitation for all by 2030. Researchers of the premier expertise institute showcased their expertise to supply consuming water freed from iron, arsenic, fluoride, and different contaminants with the assistance of their varied prototype items and modern expertise.
Arsenic and fluoride contamination in consuming water is a foremost and rising concern amongst rural folks not solely in Assam but in addition in main elements of the nation. An institute spokesperson mentioned IIT Guwahati’s expertise will help the federal government of India in offering contamination-free consuming water to the folks. Talking on the event, IIT Guwahati director Prof. TG Sitharam mentioned the availability of contaminant-free consuming water to the villagers the place pipe water provide scheme from the federal government has not but reached is a significant drawback, together with in Assam.
Prof. Mihir Kumar Purkait from the chemical engineering division has developed varied kinds of prototype items (primarily based on nanotechnology, absorption and electrocoagulation methods) for the therapy of iron, arsenic and fluoride contamination. Prof. Purkait has additionally developed and put in many water therapy crops in faculties, temples and in rural areas the place piped water provide shouldn’t be out there.
A water therapy plant (300 L/h) has been put in within the Lathiabagicha main faculty in Guwahati beneath the initiative, as this space is very contaminated with iron, excessive COD (Chemical Oxygen Demand) and the water had a nasty odor. “The college was going through points to supply contemporary consuming water for his or her college students,” mentioned Prof. Purkait, who put in a water therapy plant (300 L/h) within the faculty. The plant is able to treating TS, COD (Chemical Oxygen Demand), BOD (Biochemical Oxygen Demand), iron and arsenic from contaminated consuming water to a lot under its BIS (Bureau of Indian Requirements) restrict.
The second case has been set up of a plant for the therapy of arsenic, iron and fluoride contaminated consuming water within the well-known ‘Doul Govinda Temple’ in North Guwahati, the place the handled water is being utilized by the temple authorities for his or her day-to-day consuming water requirement. “Villagers residing close to the temple now have entry to contaminant-free consuming water. Greater than 5,000 persons are utilizing this water day by day for consuming,” Purkait mentioned.
The water therapy crops are put in as part of DST (Division of Science and Expertise) sponsored venture. It’s a digital centre inside IIT Kharagpur, IIT Guwahati, Jadavpur College, Nationwide Institute of Expertise Delhi and the Indian Institute of Chemical Expertise, Hyderabad.
