Abstract: Environmental sustainability apart from spoken at different levels needs to investigate the management of industrialactivities in terms of eco-friendliness.It is well known that effluents from various industries become a major sourceof environmental degradation in particular water pollution. Thus water analysisreport turns to be more significant, to determine the quality and standard oflife maintained in a typical ecosystem. This study includes the analysis ofphysico-chemical factors of raw as well as treated water samples from KoratturLake employing nano sized adsorbents like titania with tuned structural andmorphological properties through organic plant extract. The XRD analysis, BETanalysis, DRS-UV analysis, SEM and TEM analysis have been carried out andreported. The marked influence of leaf extract as a template is reflected inreduced crystallite size (12.4 nm) with maximum surface area 105 m2 galong with bathochromic shift of absorption edge. The usual indicators ofcontamination level at a given source namely Biological Oxygen Demand(BOD-85 ), Chemical Oxygen Demand (COD-94.5 ), Dissolved Oxygen (88 ), TotalSuspended Solids (TSS-75.6 ), Electrical Conductivity (74.5 ), Chloride (89 ),Nitrate and Phosphate contents etc. were used to ascertain the efficiency ofcontaminants removal using tea leaf extract mediated nano titania. Thereliability factor of the treatment process was found to be less than 1,revealed the effectiveness and reliability of nano material.
