Experimental Study on Physico-Chemical Parameters Using Constructed Wetlands for Lake Water

Population growth, agriculture, and industry produce more waste, straining scarce water resources and increasing conflict. This complex, sensitive, and personal issue hit hardest in the summer when local water supplies ran dry. In this paper, we report the results of an experiment we ran using the water grass Phascum australe in several artificial wetland settings. After being drawn from the lake, the raw water is subjected to a series of tests for things like turbidity, total solid, dissolved solid alkalinity, chloride content, phosphate, nitrate, BOD, and COD. Through the wetland treatment, we had successfully eliminated 80% of the turbidity, total solid dissolved solid, phosphate nitrate, and biological oxygen demand (BOD), 65% of the chemical oxygen demand (COD), and roughly 45% of the alkalinity and chloride.
