Abstract
A common treatment strategy for iron and manganese control in drinking water includes oxidation of dissolved iron and manganese followed by separation of oxidized particles from water by reverse osmosis technology. The samples are analyzed for physico-chemical parameters. Further the correlation studies among the heavy metals of water were estimated. The results were compared with drinking water standards of World Health Organization. The analytical data of pH and total dissolved solids (TDS) showed that all samples of ground water are suitable as drinking water according to the World Health Organization standards (WHO 2011). Nevertheless, Fe and Mn were noted higher than the WHO allowable limits, what would be ascribed to erosion and leaching of soil and rocks. The total removal% of TDS resulted from three compact RO units were 42.0%, 46.8% and 63.1%, respectively. In addition, our results showed that the change in ground water quality did not an influence on the quality and safety of produced water, and our study identified that Fe and Mn removal filters could play an important role in the pretreatment and quality development of final products.
