Effect of different operational parameters in the enhanced biological phosphorus removal process. Experimental design and results.

摘要

The uncontrolled dumping of phosphorus into a water environment creates serious problems of eutrophication, affecting water quality and causing grave problems in the aquatic ecosystem. European legislation drastic reduction of phosphorus dissolved in wastewater. Enhanced biological phosphorus Removal(EBPR) is the current tendency in wastewater treatment. This biological process depends on a multiplicity of variables, but its three main factors are: influent COD/P ratio, anaerobic fraction and sludge retention time(SRT). The aim of this work is to statistically determine the effect Of these three parameters in EBPR through a response surface methodology.
