Flexible biotechnological solutions for wastewater treatment - sequential bioreactors for advanced treatment in aerobic / anoxic wastewater with complex organic contaminants

Abstract

Analysis of the potential and conditions for the application of sequencing batch reactors. Adaptive SBR model to different experimental conditions, operated in anoxic and oxic sequencing phases. Sequential batch biological treatment for wastewater with high organic loading and compounds that require successive steps with different redox conditions. Study of the biodynamic of the microorganisms involved in the treatment process. Algorithms to control the treatment process on sequential bioreactors. Technological solutions for the treatment of wastewater containing groups of substances with xenobiotic & toxic character, e.g. effluents with high organic phenolic load, based on sequential batch bioreactors. Biological wastewater treatment technology in SBR system for wastewater high organic load and with toxic compounds that require successive steps of oxidation and reduction (compounds with nitrogen). The proposed technology is exploiting the SBR flexibility. The operating strategy has a certain intricacy and can be implemented for the degradation of refractory or toxic organic compounds.
