Polypropylene plant effluents

Effect of temperature on COD reduction of polypropylene plant effluent during thermolysis. CODq = 3520 mg/L, = 3 kg/m, pHo = 6.53, P = self-pressure, (a) COD reduction with time, (b) First-order kinetics at different temperatures. 

The kinetic equation for catalytic thermolysis of the polypropylene plant effluent for temperature in the range of 40-160°C, catalyst mass loading in the range of 2-5 kg m and at pHfl = 6.65 may, thus, be written as...

The wastewater was collected from the effluent treatment plant of a polypropylene plant production unit situated in northern India. The wastewater was stored at 4°C in a refrigerator in the laboratory and was subsequently used in the experiments without any dilution. All chemicals used in the experiments were of analytical reagent (AR) grade. Copper sulphate (CUSO4 5H2O), anhydrous ferric chloride (FeCy and ferrous sulphate (PeS04 7H2O) were procured from M/S, RFCL, New Delhi.
