ABSTRACT
The development of a mathematical model to predict the concentration of carbonates in effluent discharged from a brewery industry is the aim of this paper. This was achieved by obtaining effluent data for several years and using the method of least squares to develop the model. A mean deviation of 9% was observed by comparing the experimental data with the simulated results. The constituent parameter with the greatest influence on the simulated model was found to be sodium ion (Na+) with a coefficient of 0.87642 while that with the least effect was the temperature with a coefficient of 0.0514255. In addition, a control model was developed to monitor the conversions of the effluent constituents in three Continuous Stirred Tank Reactors (CSTRs), some deviation was observed between the set-point values and the empirical values.
