MULTI SENSOR SYSTEM FOR FAST ANALYSIS IN ENVIRONMENTAL MONITORING WITH AN APPLICATION IN WASTE WATER TREATMENT

The presented mobile multisensor system consists of a LIF spectrometer, a reflection spectrometer, and sensors for temperature, pH value, redox potential, and conductivity for in situ investigations. Additional sensors can be integrated easily. This system is suitable for a fast analysis of a great number of samples (environmental monitoring). The very short measuring time and the low costs of measurements are the main advantages of the system in comparison with the chemical standard analysis. One example of a wastewater analysis shall demonstrate the characteristics of the system. A neural network shall be used as a model for the evaluation. The system can be adapted to various tasks. The margin of error varies between 5% and 25% in dependence on the application.
