Abstract
A water integrity control and disinfection method and system that measures key water parameters and can diagnose water integrity instability trends that result in loss of water integrity. Relevant water parameters that are predictive of water integrity such as cell null value as measured by in-line colorimetry provide early warning and prediction of problematic trends in the water integrity so that the system can pro-actively respond appropriately and prevent, mitigate or reverse the instability trend and maintain microbiological control of the water supply.
Claims19
A method for predicting water instability and mitigating loss of water integrity in a water system, the method comprising:
- providing a disinfectant pump comprising a processor for controlling the pump to maintain a disinfection setpoint, the disinfectant pump connected to a chemical disinfectant supply to inject chemical disinfectant into the water system;
- diverting a water sample from the water system to a disinfectant concentration measurement system comprising an in-line colorimeter;
- at the in-line colorimeter, measuring a disinfectant concentration of the chemical disinfectant in the water sample periodically over time to provide a real-time measurement of the fluctuation in disinfectant concentration in the water system;
- in a processor, analysing the fluctuation of the disinfectant concentration over time from the colorimeter to detect an instability trend in the disinfectant concentration over time before a loss of water integrity, the instability trend in the disinfectant concentration over time predictive of a future water instability event;
- and
- when an instability trend in the disinfectant concentration over time is detected, adjusting a water parameter to mitigate the loss of water integrity in the water system.
A system for controlling water integrity in a water system, the system comprising:
- a disinfectant pump comprising a processor for controlling the pump to maintain a disinfection setpoint, the disinfectant pump connected to a chemical disinfectant supply to inject chemical disinfectant into the water system;
- a water quality database for receiving and storing water quality parameter data from the water system over time;
- an in-line colorimeter receiving a water sample from the water system and measuring a fluctuation in disinfectant concentration of the chemical disinfectant in the water sample periodically over time;
- and
- a processor for analysing the fluctuation of the disinfectant concentration over time from the colorimeter to detect an instability trend in the disinfectant concentration over time before a loss of water integrity, the instability trend in the disinfectant concentration over time predictive of a future water instability event, and providing a prescriptive remedy based on the instability trend and water quality parameter data for reversing the instability trend comprising adjusting a water parameter to mitigate the loss of water integrity event.
