ASET Colloquium

Radiation Technology for Cleaner India

by Dr. Lalit Varshney (Head, RTDD, BARC, Mumbai)

Friday, July 6, 2018 from to (Asia/Kolkata)
at AG-66.
Description
In India about 40 billion litres of Sewage is generated every day and it is discharged into water bodies after treatment at sewage treatment plants (STPs). The thickened sludge from the STP is sun dried or filter pressed to form  dry sludge, which is used as land fills or supplied to farmers. This practice results in spread of diseases and ground water contamination. A 1.5 MCi 60Co Dry Sewage Sludge Hygienisation Facility has recently been established in Ahmedabad. This  facility has paved the way for tackling sludge menace in populated cities using Radiation Technology. Here, the  dry sludge is irradiated to 10 kGy radiation dose and then sprayed with Bio-NPK micro-organisms to make it into a bio-fertilizer. Another major problem is the contamination of water by dyes, Arsenic, Fluoride and Chromium.  Radiation technology can produce advanced materials which can pick up these contaminants and clean thousands of litres of ground water every day.
