Nature can self-purify itself using complex physical, chemical, and biological processes. Similarly, rivers also have the capacity for self-purification, but it is insufficient to meet the present-day pollution levels. So, we can artificially increase its self-purification capacity with minimal disturbance to equilibrium in the environment. One such process is Whirlpool which has a natural capacity of reducing pollution levels and can increase the water quality to consider. The turbulence generated can also be dissolved oxygen (DO). The froth formed during the whirlpool formation can act as a site of coagulation of inorganic as well as organic pollutants. The hydro-cyclone modified as whirlpool can be mainly used to separate the oil from water coming from hydroelectric power plants, thus increasing water quality for irrigational purposes. These artificial whirlpools can be created near river rapids where the flow velocity is expected to increase. The modified hydro-cyclone is designed based on the cut-size formula.
