ABSTRACT
The water industry is facing increased pressure to produce higher quality treated water at a lower cost. The efficiency of a treatment process closely is related to the operation of the plant. To improve the operating performance, an Artificial Neural Network (ANN) paradigm has been applied to a water treatment plant. An ANN which is able to learn the non-linear performance relationships of historical data of a plant has been proved to be capable of providing operational guidance for plant operators. A back-propagation network is used to determine the alum and polymer dosages. The results showed that the ANN model was most promising. The correlation coefficients (r) between the actual and predicted values for the alum and polymer dosages were both 0.97 and the average absolute percentage errors were 4.09% and 8.76% for the alum and polymer dosages, respectively. The application of the ANN model was illustrated using data from Wyong Shire Council’s Mardi Water Treatment Plant on the Central Coast of NSW.
