Abstract:Chlorine has been used as a standard for disinfecting wastewater for many years. While being the standard There are many levels of automation for control of disinfection. To select the best control approach for your facility both control strategies and chlorination chemistry must be understood. Permit conditions must also be fully identified; organism concentrations and operational data. Many States require compliance with both organism concentrations and residual chlorine concentrations.
Breakpoint chlorination chemistry plays a role in most chlorine disinfection systems. This paper discusses blending on-line monitoring and automated control with chlorine chemistry to develop several levels of process control that will work. Disinfection byproduct formation must also be considered while developing a process control strategy. Trihalomethanes are being regulated in wastewater effluent and the water quality based limits are much stricter than SDWA drinking water standards.
This presentation will highlight the key operating factors for maintaining chlorine gas disinfection systems. Check lists developed from working with successful operations staff will be presented that will allow users the most update information on the operation of chlorine gas disinfection systems.
