The roots of Water hyacinths (WH) and some other aquatic plants naturally absorb pollutants as well as some organic compounds which are carcinogenic and have concentrations of approximately 10,000 times that is present as in generically found water. WH can be cultivated for waste water treatment and it can be used to aid the process of water purification either for industrial waste water or sewer water, in addition to available techniques. The root structures of Floating aquatic plants provide a suitable environment for aerobic bacteria to remove various impurities present in water. This study attempts to evaluate the effect of WH in Domestic Waste water (Grey Water). Further, the reading for various parameters like Turbidity, pH, Chemical oxygen demand (COD), Biochemical Oxygen Demand (BOD), Dissolved Oxygen (DO), TSS, TDS, Conductivity, Chlorides, Nitrate, Phosphate, Total Acidity, Total Alkalinity, Total Hardness has been periodically taken every 24 hrs for 5 days. The effect of Water Hyacinth has resulted in significant decrease in turbidity and due to which the removal of flocs and reduction in organic matters in water have been observed. The primary purpose of this study is to make use of the water hyacinth plant for the purification of Domestic Wastewater.
