Conventionally, water Purification system contains two important purification stages, namely Carbon Filtration and Reverse Osmosis (RO). There has been significant research work reported in the
literature on enhancing the RO water purification efficiency. Moreover, for obtaining desired quality of water as well as the production rates, the importance of system engineering is evident. We present two fold contributions in this field, (1) prepared and used candle flame soot as Nano carbon tubes as the dsorbents. An adsorption purification stage with carbon Nano tubes has been used before the RO stage in the water purification system. Experimental study of the purification system with and without Nano tube filtration
stage has been presented. (2) Experimental study of transient analysis of RO system has been presented to understand the dynamics of the two stage process. The effect of feed pressure, water feed rate, and
ratio of rejected and retentate flow rate have been investigated on the water quality.by N V Ravi Teja Chintala and Nitin Padhiyarby N V Ravi Teja Chintala, and Nitin Padhiya
