Abstract: Because of the complex structure and the numerous parameters of existing models for the activated ,sludge, wastewater ,treatment, process (WWTP), there are great difficulties to directly apply the models in simulation systems. In order to enhance the practicality of the models for the WWTP, a simplified ,model, is developed based on the activated ,sludge model, No. 1 (ASM1), which is the ...
