RESULTS The Hydrodynamic Vortex Pretank Rainwater Filter removes substantial amount of pollutants from runoffs origin of various locations. The quality of post filtration water is tested for the same Physico-Chemical parameters that have been considered in the test of runoff water earlier. The results are shown below in Table 7.

ISSN: 2347-1697 International Journal of Informative & Futuristic Research (IJIFR) Volume - 3, Issue -12, August 2016 Continuous 36 th Edition, Page No: 4626-4649 The following are the data obtained from real world situation for comparison and correlate the filtration capacity of this filter and assess it robustness. Average rainfall in India is 0.8 inch/hr Average highest rainfall in India is 1.909 inch/hr Average peak time rainfall of the highest rainfall place in the world, Cherapunji is 3.968 inch/hr (in July)a .The result of simulation of the designed filter model in theoretical model simulator for an area of 30000 sq.ft is given below.
