Abstract

A method and system for measurement of chloramine species concentrations in a chlorinated water system or reservoir and the air above the water reservoir in an indoor environment. Colorimetric methods in combination with a controlled and delayed reaction cascade of chlorine species reactions can be used to differentiate between chloramine speciation in chlorinated test water such that the trichloramine content in the water and air can be accurately determined, providing an indication of trichloramine concentration in the air in the indoor environment. Remediating measures can be taken based on the chlorine species concentration.

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.

Abstract

A system and method for controlling microbiological growth in a water system and premise plumbing system which uses stabilized hydrogen peroxide as a disinfectant and maintains water energy matrix control. Maintenance of stable hydrogen peroxide residual in the system in combination with active temperature monitoring enables better control of the water energy matrix and reduction of hot water temperature while maintaining microbiological control.

Abstract

A system and method for measuring disinfectant concentration in and disinfecting dark water and controlling dark water quality. The system has a dilution pump to dilute a dark water supply, and an colorimetric analytical apparatus for measuring the amount of disinfectant in the diluted sample. A disinfectant reservoir provides disinfectant to the dark water supply in response to the colorimetric measurement obtained from the measurement cell to maintain the residual disinfectant concentration in the dark water at an appropriate level.
