Nonlinear model identification of waste water decomposition processes in a hybrid plasma torch

The aim of this paper is to present a method for the estimation of the nonlinear model of the organic waste water plasma decomposition. In the first part of the paper, the models of the plasma arc generation, available in the literature are presented. The subsequent parts of the paper emphasize on the methodology, the model of the waste water plasma generator, the laboratory experiment organization and the experimental results. The experiment - designed for real-time control - proved that, under given conditions, the on-line identification of the process is possible with general purpose apparatus.
