ON-LINE MONITORING OF WASTEWATER TRUE COLOR USING DIGITAL IMAGE ANALYSIS AND ARTIFICIAL NEURAL NETWORK

Application of the digital image analysis (DIA) method to develop an effective and economical method for on-line monitoring of the wastewater true colour. Experimental results show that the DIA method performed not only with good accuracy and precision but also high sensitivity in the measurement of true colour. Comparison with ADMI3 and 31WL values. Proposition of a back-propagation neural network to calibrate all the values.
