----- Figure 3 shows the reductive degradation ~ystem. The reductive degra- dation process operates by first neutralizing (pH 7) the acid wastewater (pH 3 to 4) in a pH adjustment tank. After neutralization, the wastewater passes through reductant columns (in parallel) packed with copper-catalyzed iron and sand, and the endrin is destroyed.

Abstract- Control of pH (hydrogen potential) ,neutralization, process has always been one of the challenging problem in process control particularly in ,wastewater, treatment. However, it is difficult to control a pH process with adequate performance point due to its nonlinearities, time-varying properties and sensitivity to small disturbances when working near the equivalence point.
