N2 - Plating processes generate various types of wastewater including, acid, alkali and metal containing wastewater. Traditional wastewater treatment processes are conducted based on basic measurements and dosing. This kind of treatment results in overdosing/under-dosing of treatment chemicals due to variations in flows, concentrations and operating conditions. It would be ideal to predict, in advance, the efficiency of wastewater treatment based on variability of concentrations, flow rates and dosing. This paper proposes a model for the treatment of typical wastewater from a chrome plating process. This includes wastewater from degreaser, acid and the chrome plating tank. The paper provides a detailed study of pH adjustment and chromium treatment. The model results show the response of treatment process to changes waste composition. A Mat Lab simulation is used to illustrate variations in operations.
