Computer-assisted modelling of wastewater treatment

Computer-assisted modelling of wastewater treatment is becoming more and more popular and is particularly useful for the design and optimization of wastewater treatment plants. Popular models such as the Activated Sludge Model No. 3 (ASM3) consist of a series of differential equations which describe biochemical reactions which occur during biological treatment. Computer programs are typically required to solve these equations numerically as exact solutions cannot be derived.
