Industrial effluents discharge into the environment has been on the increase in recent years and this has led to the deterioration of the environment, there are changes in both the physical and chemical characteristics of these places and in particular a remarkable change in the pH values. This paper gives an evaluation of effluent from electroplating industries and further proposes a developed model for the prediction of the pH as a function of five different parameters of Total Suspended Solids (TSS), magnesium ion (Mg 2+), calcium ion (Ca2+), total metal and dissolved oxygen. Parametric coefficients in the model equation obtained showed that the effect of dissolved oxygen and calcium ions are higher than the others. Results of analysis reveal that the values of TSS were much higher than the set limits while the others were within manageable values. Simulation results on the pH show various degrees of variations form experimental, the reason attributed to this was the limited number of parameters considered in model development.
