The trial of regeneration of used impregnated activated carbons after manganese sorption Original Research Article

In recent years, the increasing level of underground water shows a high iron and manganese concentrations, thus, the technology of water treatment requires application of processes for Fe and Mn removal. Within a literature, many treatment processes have been proposed for manganese removal from drinking water, however very often they do not comply with the obligatory quality standards and are not suitable for practical application. Activated carbon adsorption is considered to be a particularly competitive and effective method, mainly because of large specific surface area. In addition, due to physical and chemical properties, activated carbon has a wide range of applications, e.g., it is used as a sorbing and catalytic agent or a catalyst carrier.
