I received today a DO Letter bearing number 12074/3(6) dated 7.5.12 from Mr Ranjan Chatterjee, Consultant, Planning Commission, Delhi indicating that the Bhabha Atomic Research Centre has developed a radiation treatment of sewage sludge which offers an "efficient, simple and reliable method to produce pathogen-free sludge which can be further upgraded to nproduce bio-fertiliser".
I'd met Mr Chatterjee during last year's Plan discussions at Yojana Bhavan, at Delhi. We are making many Sewage Treatment Plants under National Ganga River Basin Plan (Kalyani, Bhatpara, Gayeshpur etc), JNNURM (by KMDA/ KMWSA/ UD) and at New Town Kolkata (by PHED/Hidco). I am also concerned about the state of affairs of Salt Lake STP where a team from World Bank had recently visited at my request. Indeed, sewage disposal is a huge problem and even if there are STPs, fecal coliform and other microbes are difficult to destroy. As such, nuclear radiation treatment would be a great possibility. (It will also allow me to connect with my Post MSc days in Saha Institute of Nuclear Physics !!).
I plan to contact Mr Chatterjee as soon as I can.
