Design and Implementation of Online Real-Time DisinfectionPerformance (CT) Monitoring Systems

摘要

The regular monitoring of disinfection performance (CT) at water treatment plants (WTP's) is animportant function for facility operators to verify the proper operation of disinfection systems and thequality of the treated water. In North America there is a regulatory trend towards the mandating of CTmonitoring and reporting, and the Province of Alberta, Canada recently required The City of CalgaryWaterworks to design and implement online real-time CT Monitoring Systems. This paper provides adetailed summary of key design lessons and issues that should be considered by other WTPoperators interested in pursuing a similar manual or fully automated system for their facility. Thepaper discusses the possibility and approach of creating only a computer spreadsheet model toprovide CT Calculations for any WTP, and then extends the discussion to the full automation of thatmodel for online real-time functionality. The implementation and use of a powerful CT Simulator forsystem contingency is discussed, and the process optimization and cost saving benefits that the Cityreceives from having implemented the Systems is high-lighted.
