Wastewater Minimization of Starch Industry using Water Pinch Analysis and Comparison with Water Design Software

Authors(2) :-G. Yesaswini, R. Saravanathamizhan

The aim of the present work is waste water minimization using water pinch analysis and compares the result with water design software for a starch industry. Water pinch analysis is a graphical methodology for fresh water and waste water minimization. The results obtained using water pinch analysis formulation for water reuse of a starch industry leads to a reduction in freshwater demand of 59.16 t/hr with a fresh water pinch of 60ppm and an outlet average concentration of 224.19 ppm. The results obtained by graphical approach have been compared with water design software. It is observed from the present result that the water pinch analysis formulation technique can rapidly yield accurate minimum water targets, pinch points and the average outlet concentration of a starch industry which could be useful in management decisions. The water design software result closely matches with the graphical calculation.
