Method of controlling waste water purification plants using quality evaluation of measuring data
First Claim
1. A method of controlling a waste water purification plant comprising the steps of measuring at least two parameters and automatically controlling the plant on the basis of the measurement values obtained using a mathematical model for the purification process, comprising evaluating the quality of the measurement value for at least one parameter on the basis of a comparison of said value with an expected, dynamic value interval calculated continuously on the basis of the mathematical model and a simultaneous measurement of at least one other parameter, and controlling the plant on the basis of said evaluated measurement values.

Abstract
A method of controlling a wastewater purification plant comprises the steps of measuring two or more of a number of parameters, automatically controlling the plant on the basis of the measurement values obtained using a mathematical model for the purification process, evaluating the quality of the measurement value for at least one parameter on the basis of a comparison of the said value with an expected, dynamic value interval calculated continuously on the basis of said mathematical model and a simultaneous and/or a previous measurement of one or several other parameters and/or a previous measurement of the same parameter, and controlling the plant on the basis of the quality evaluated measurement values.
