Abstract
AbstractThis study was developed using data from a drinking water treatment plant located at Boudouaou, Algeria, it is located at about 7 km from the Keddara dam which supplies potable water to Algiers capital of Algeria. The treatment consists essentially of preliminary disinfection, coagulation–flocculation, settling, filtration and final disinfection. Traditionally, optimum coagulant dosages are determined using jar tests. However, jar tests are relatively expensive and time consuming. In this study, we present a new Artificial Intelligence Techniques model called dynamic evolving neural-fuzzy inference system (DENFIS) based on an evolving clustering method, for modelling coagulant dosage rate used in the coagulation stage. Six online variables of raw water quality including turbidity, conductivity, temperature, apparent colour, ultraviolet absorbance, water pH and alum dosage were used to build the coagulant dosage model. Two DENFIS-based evolving neural-fuzzy inference system are presented and compar...
