Abstract

Electrochemical cells used for effluent treatment may, in many cases, require automatic control to handle load changes in the waste discharge. Results are presented for the automatic neutralization of a simulated chloralkali waste-acid stream using hydroxyl generated by an electrochemical cell operating under current control. The performance of a simple analogue PID controller is compared with that of a modern microprocessor-based adaptive controller.
