Disinfection Control

September 26th, 2012

This well-received workshop was held in Edinburgh and with a good attendance of 50 delegates. The workshop was hosted by the Scottish Government and Drinking Water Quality Regulator and chaired by Ian Walker of WRc. The first presentation by Matt Bower of DWQR set the regulatory perspective on Disinfection Byproducts. Simon Parsons of Scottish Water then discussed the water company perspective of DBP issues. The next presentations provided examples of methods used to minimise byproducts, including advanced coagulation control (Roger Powell of Process Measurement and Analysis) and streaming current monitoring and coagulation control (Mike Riding, Process Instruments).

Delegates then heard about online monitoring of THMs through a presentation by Dr Emma Goslan of the Cranfield Water Science Institute on the ROI model for management of THMs; and online monitors/sensors for THMs by Dr Michael West of Aqua Metrology. We then heard about how to control THMs in drinking water from Dr Mark Brown of Multisensor Systems Ltd. Finally we learnt about how disinfection by products affect residual chlorine monitors, and to always question the accuracy of measurements from Mike Strahand of Analytical Technology.
