The potential of activated carbon ETAC and Polymer Composites (PAC and PPC) for the removal coloring matter from industrial effluents were analyzed. All the three adsorbents were prepared from the precursor Euphorbia Tirucalli L wood. After the treatment there was significant decrease in pH, Hardness, TDS, DO, BOD and COD of industrial effluents. Among eight samples studied, after the treatment almost all samples were colorless except sample 4 for ETAC, sample 7 and 8 for polymer composites. Cost analysis for the preparation of adsorbents and treatment of effluents were carried out. The cost for treatment of effluents with ETAC and Polyaniline Composite are more economical than commercial charcoal.Keywords

Background/Objectives: An adaptive Proportional Integral (PI) controller for a conical tank liquid level process is simulated in MATLAB platform. Methods/Statistical analysis: The Scheduled PI and Internal model control (IMC) based PI performance are compared in terms of settling time rise time, overshoot, Integral of Squared Error (ISE), Integral of Absolute Error (IAE), Integral Time Absolute Error(ITAE) and disturbance rejection. For IMC based PI tuning, the exact model of the process obtained by on line estimation of process gain and time constant. Findings:The IMC based tuning procedure ensures good performance by Proportional and Integral (PI) controller. The Ziegler Nichols (ZN) tuning rules and estimation based tuning are used for scheduled Proportional and Integral (PI) and internal model control based PI controller. Applications/Improvements:Derivative controller can be added to this PI controller for distillation process.Keywords
