In this present work, the effect of lignocellulosic biomasses on the water treatment efficacy of Porur lake was investigated. Microwave treated lignocellulosic biomass was prepared followed by seeding into the water samples that collected from Porur lake. Water treatment efficacy was done with a total of 28 samples that were split into two groups. 14 samples were obtained for pre-treated water (Group 1) and 14 samples were taken for novel post-treated (Group 2). Calculating power at 0.85 G. The parameters alpha and CI (Confidence interval) are taken into consideration. Using SPSS (Statistical Package for the Social Sciences) analysis, a significant value of 0.01 (p < 0.05) was determined. Followed by measuring water quality parameters. Determination of changes in the respective parameter of control and lignocellulose biomass treatment revealed the adsorption or water treatment efficacy. Results showed that the number of inorganic pollutants were significantly reduced in lignocellulosic biomass treated water samples that derived during the novel pre-monsoon season (significance difference of (2-tailed) 0.01(p < 0.05)). From these findings it is very clear that lignocellulose biomass can be used in the water treatment process as their high efficacy in pollutants removal.
