Many controlled variables in the process realm behave linearly, but pH adjustments exhibit non-linear behavior. Traditional control methodologies like PID loops may be inadequate for pH adjustments due to their non-linear nature. For example, titrating a weak acid with a strong base results in drastic pH changes. This non-linearity poses challenges for achieving target pH values efficiently in industrial processes. Implementing pH-stat control systems can provide a more effective solution for managing pH levels in complex reactions. These systems offer dynamic adjustment capabilities that can accommodate non-linear pH behavior, leading to more precise control and improved process efficiency.
