Stochastic Modeling and Optimization of Process Parameter of A Coagulation Process in Water Treatment Using a Hybrid Coagulant by Response Surface Methodology

S. Revathi and S. Naveen kumar

Design of experiment uses a series of structured analytic method to investigate the relation between parameters and the responses. The particular technique used in this study is response surface methodology. Using the DOE approach, a mathematical based model was developed to study the response prediction. Effectiveness of important process parameters Al/Si molar ratio, OH/Al molar ratio, pH and dosage were determined, optimized and modeled successfully. Significant quadratic polynomial models were obtained.
