1/12/2007, · The principal objective in ,waste water, treatment is to eliminate or reduce contaminants to permissible level that cause no adverse effects on humans or receiving environment. Generally, the remediation of the ,acid, mine ,waste water, requires pH adjustment, physical oxidation or reduction, ,neutralization, and heavy metal removal.

----- 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.
