In this paper, it has been proved that in wastewater purification technology from dyes the adsorption methods ensure practically the complete removal of all dyes. Modified activated carbons, obtained by semi-industrial scale from local renewable raw materials such as cobs, nut shells and grape seeds, have been tested for use in the detoxification technologies of aquatic environment. A significant role in this research is given to adsorption mechanisms of refractory substances on carbon adsorbents. As a result of the physicochemical study of adsorption processes, a scheme of the wastewater purification from dyes has been developed. Their amplified efficiency, in comparison to imported activated carbons, has been demonstrated in experiments, carried out at stations of surface water and groundwater purification, as well as at wastewater treatment plants. At this time, scientific research of the feasibility study and business plan for the economic unit of production of activated carbons, based on local raw materials in the Republic of Moldova, is in progress.
