Catalytic Augmentation Methods for Nutrients Removal Process from Wastewater

Abstract

For carrying out processes of complete removal of organics, nitrogenous compounds, phosphates in standard schemes of biological treatment there is need significant amount of time for wastewater treatment (up to 14-20 hours), that leads to plants expansions, and therefore extension of space, allocated for wastewater treatment plant, increasing of activated sludge concentration, energy consumption for air delivery in aeration chamber. For decreasing of operation and capital costs, increasing of pollutants removal on the biological treatment stage, there was offered using of heterogeneous metal-complex catalysts in the shape of reticular modules. This solution, as opposed to alternative methods of biological processes augmentation (usage of membrane techniques, carriers of attached microbial flora, increasing of oxidation capacity, for account of additional capacity of blower), allows decrease producing cost of wastewater treatment, right size operating personnel, withdraw from usage of expensive reagents, that leads to decreasing of producing cost unit of wastewater treatment.
