A Design of Experiments (DOE) Approach to Parameters Optimization of Sludge Treatment System in an Enzyme Preparations Factory

Abstract:

To decrease the influent load of the wastewater treatment system and increase the overall ability of the wastewater treatment plant to meet the demand for 15% production expansion of the enzyme preparations factory, the purpose of this study was set to decrease COD concentration of the centrate from the sludge treatment system. Three orthogonal experiments and follow-up analysis of experiment results identified the significant impacts factors on COD concentration of the centrate. Afterwards, four full factorial experiments were designed to obtain a set of optimum parameters combination on the condition that no GMO was detected in the dewatered sludge.
