The Department of Science & Technology, Govt. of India Project amounting to 21.0 Lakhs from 2011-2014 is successfully completed being initiated by Dr P C Sabumon – Professor, School of Mechanical and Building Sciences. The aim of the Project is to find ‘Development of Single Stage Reversible Flow Bioreactor for Simultaneous Removal of COD and Ammonia from Wastewater’. Some Interesting findings are Nanoscale oxyhydroxide of Fe (NOF) assisted sustained anoxic ammonia removal, Facile and ecofriendly approach to synthesize NOF, Redox cycling of Fe coupled to microbial nitrification and denitrification, NOF were stable for several cycles of operation, Economical process in the absence of external supply of aeration and alkalinity with the possible application (s) in the Economic removal of low to moderate concentrations of NH4-N from wastewater or Industrial effluents.
