Abstract:
A trial treatment plant model was constructed and the performance of the model was found to be effective as an effective technique for removing iron and other contaminants from groundwater. With an effective size of 0.45 mm, a uniformity factor of 1.5 and a porosity of 0.6, the filter material was able to filter water with a high iron content and other parameters. The backwash speed of the sand filter is 1.44 m/s (86.4 m/h). At this speed, the pressure was sufficient to cause the media to expand and boil, so that the iron sludge, flakes and other dirt remained in the filter. Nine (9) daily inflows and outflows at depths of 60 cm, 70 cm and 80 cm were determined. An iron removal efficiency of 99.1% was achieved at a depth of 60 cm and 90.63% at a depth of 80 cm. Similarly, the model was able to remove physical and organoleptic parameters (color, turbidity, fluorine, manganese, nitrite, Ph, zinc, E-coli and total coliforms). The technology developed in this research can be used as an alternative, simple and cost-effective way to remove iron and other contaminants from groundwater.
