Assessment of household reverse-osmosis systems in heavy metal and solute ion removal in real and synthetic samples
In this study, the efficiency of household reverse-osmosis system (HROS) with and without neutralizer accessory was investigated in both real and synthetic samples. The real samples were collected from rural and urban public drinking-water systems with and without primary refinery treatment. The sel...
