Among the used methods of iron (II) oxidisation, the best effects have been achieved by potassium manganate (VII) because one of the oxidation products was manganese oxide (IV) precipitating from water. Better results in purifying the water were obtained with the use of a prehydrolysed coagulant Flokor 1.2 A than aluminium sulphate (VI).}, type={artykuł}, title={The impact of potassium manganate (VII) on the effectiveness of coagulation in the removal of iron and manganese from groundwater with an increased content of organic substances = Wpływ mnanganianu (VII) potasu na skuteczność koagulacji w usuwaniu związków żelaza i manganu z wody podziemnej o podwyższonej zawartości substancji organicznych}, keywords={groundwaters, iron, manganese, organic substances, potassium manganate, coagulation, wody podziemne, żelazo, mangan, substancje organiczne, manganian potasu, koagulacja}, }
