Abstract—The Nitrification process in wastewater treatment is one whereby two particular aerobic bacteria – Nitrosomonas and
Nirobacter – are used to biodegrade dissolved ammonia in the effluent to produce nitrate compounds. This decomposition process
comprises of several components that interact together mutually changing their magnitude and consequently affecting the
bacterial population. In this paper, a simulation of the nitrification process using Fuzzy Logic is described. The resultant
application is a comprehensive system that approaches the real life model, providing a clear insight of the biodegradation process
during nitrification. Experts can use the software to optimise the process in order to maintain a healthy nitrification to remove
nitrogenous matter from the wastewater more efficiently.
