The main concept is based on the interaction of chemical pollutants NO<sub>2</sub>, NO<sub>3</sub>, BOD<sub>5</sub>-in, and BOD<sub>5</sub>-out and heavy metals with microorganisms as Chlorophyta Green and cyanophyta, and how these oxidation ponds imitate the Continuous Chemical Reactor (CSTR) to build its core architecture for maximum usefulness. By applying the theoretical equation of (CSTR) on the experimental results of the oxidation pond according to Thirumurthi equation, it was discovered that (CSTR) and oxidation pond are matching together with a satisfactory ratio of congruence (85% - 88%).

This investigation established that the oxidation ponds may function as a Continuous Chemical Reactor under ultimate conditions and precautions.展开更多
