| Abstract |
This paper presents a biological reaction model of describing processing features in treating wastewater via activated sludge. A proposed model is designed by combining fuzzy rules investigating several elements which have influence on variables to be supervised. BOD and SS are suggested as common variables in input and output variables, and O₂ quantity is proposed as input variable. We chose triangular type membership functions for input variables and determined the grades in each membership function based upon process data. According to simulation result to show the validity of proposed model, fuzzy model"s outputs give almost similar data to process output under same input conditions. |
