Acid Waste Neutralization (AWN) systems adjust the pH of process waste water to within acceptable limits (typically 6 – 9) before discharging to the facility sewer connection. Reagent chemicals such as Caustic Soda and Sulfuric Acid are metered into reaction tanks at a rate proportional to the difference between the measured pH value and the target set point.

Neutralisation unit is responsible for processing the waste water from regenera- tion process of demin unit, in order to dis- pose it in the sea. Two models are derived. A pilot model of 1 tank and a real 2 tanks model as it al- ready exists at the factory. Both of them are modelled and linearised.
