Optimization methods as useful tool for wastewater treatment management (Artificial NN, Response Surface Methodology, mathematical programming)
Abstract The UV/H2O2 process has often been proposed as an effective treatment technology
for remediation of colored wastewaters.
Descrizione Description including main features/advantages
The proposed optimization approach combines the response surface methodology and
mathematical programming. Flowchart in Fig. 1 represents the activities within the
framework of the proposed approach. After the pre-screening (preliminary
experimentation), an appropriate experimental design is selected, the experiments are
performed, and the results are analyzed (modelling of responses, statistical analyses).
If statistical tests regarding the obtained response models (polynomial approximations)
produce unsatisfactory results, modifications in response surface modelling and/or
experimental design are required. If the statistics is satisfactory, the obtained response
models are used to formulate an appropriate optimization problem, which is solved
using a software for constrained optimization.
The results indicate that if the simultaneous optimization of operating parameters and
costs is used, a significant improvement in economic efficiency of the treatment
technology can be achieved. For the case studied, the operating cost of the treatment
process optimized solely with respect to the maximization of operating efficiency could
be up to 5.5 times higher than those obtained using the proposed approach.
Innovative aspects
An optimization procedure through which the treatment technology was simultaneously optimized from the perspective of operating and economic efficiency. Current and potential industrial users/domains of application
Wastewater treatment - cost reduction. Current state of development
Tested on laboratory scale (model wastewater).
