Removal Of Iron From Ground Water

Removal of iron from ground water: Uganda is one of the iron rich countries, with some parts having as high as 50mg/l  concentrated in ground water. Iron is a troublesome element in water supplies and  efforts to manage the problem have involved the installation of iron removal plants (IRPs) on one hand, and the conversion of U2 pumps to U3 Modified pumps coupled with chlorine dosing. ATC research indicated that in many boreholes iron is introduced as a result of corrossioin though in some others it is as a result of dissolved iron from soils and rock formation as water seeps, percolates and drains down soils and rocks. Apparently, the IRP being promoted is only effective for iron below 10mg/l. The efficiency of the IRP greatly reduce beyond iron concentration of 10mg/l and under such circumstances, the residual iron is above the national drinking water standard of 0.3mg/l. Upon that background ATC is working to improve efficiency of IRPs.
