In this study, a typical chlorine control application called KhloCheq has been developed. KhloCheq seeks to control chlorine concentration at the disinfection stage of water and wastewater treatment. The application was developed using Visual Basic programming language. The application can operate in both manual and automatic modes during chlorine disinfection. In the manual mode, KhloCheq alerts an operator by sounding an alarm and suggesting the percentage by which chlorine supply rate should be increased or decreased when the measured value is not equal to the set point. In the automatic mode, the application automatically adjusts the chlorine concentration to the desired value with the help of chlorine analytical transmitter, controller and final controlling element. The application also uses feedback and feed-forward process control mechanisms to adjust chlorine concentration to the set point. KhloCheq can be very useful for disinfection in water and wastewater treatment facilities when the right analytical sensor is used. This will ensure that the right amount of chlorine injection is used for disinfection to avoid any adverse impact on the environment.
