This week’s snow didn’t spoil the ATi sponsored Swig meeting at the Etihad Stadium in Manchester, which looked at The Role of Sensors in Disinfection and Microbiological Monitoring. SWIG logo


Speakers from the water industry and suppliers attended the event and ATi’s very own Dr Chlorine, General Manager Mike Strahand, gave a presentation on the state of chlorine monitoring


Drinking water must be ‘wholesome’ and this is defined in law by standards for a wide range of substances, organisms and properties of water in regulations. Compliance with the strict UK and European standards is very good in the UK: England and Wales achieved 99.97% compliance. A small number of failures do occur; can the improved use of sensors and the application of emerging technologies help?


SWIG photoChlorine is used as a primary disinfectant in water treatment and is also added to protect the water during distribution to the tap. Chlorine has made the greatest contribution to the prevention of disease from drinking water worldwide and the technologies for monitoring and control are well established. Alternatively, rapid microbiological monitoring and detection is extremely challenging and developing reliable sensors has kept researcher and instrument developers busy for many decades.


This workshop looked at both current practice in chlorine monitoring for water treatment and the use and potential benefits of emerging technologies for microbiological monitoring.
