CSC Services enjoyed an evening seminar at Northumbrian Water yesterday, hosted by the Institute of Water. Water professionals heard from two great speakers on the subject of water quality, disinfection byproducts and Trihalomethanes.

Northumbrian Water’s Technical Advisor John Coulson explained the company’s ‘source to tap’ approach to water quality and identified the company’s outcomes and measures of success. John spoke about the hot topics relating to water quality for Northumbrian Water which include discoloured water, trihalomethanes and the industry wide issue of metaldehyde, on which the company are collaborating with Newcastle University and other water companies to research new treatments.

Following this, Ethan Brooke, an expert on disinfection byproducts from San Francisco introduced PAX Water technologies and their approach to removing trihalomethanes. Following an overview of the chemistry of DBPs and THMs, Ethan explained how they can be removed efficiently to levels below regulatory limits through a range of different in-tank aeration technologies including bubble aeration, surface aeration and spray aeration.

Ethan provided an example of a surface aerator system which had achieved results in San Jose, California, and he provided an overview of the first install for Scottish Water of a spray aeration system.

Speaking about the seminar, Lyndsey Gilmartin, Marketing Manager for CSC Services said:

“The session was very informative, and it was very clear to see how in-tank aeration technologies could be a useful tool in dealing with the very complex issue of Trihalomethanes.

“As a specialist contractor providing protective coatings and leak sealing solutions, it is very important for us as a company to learn about these latest technological developments. In the long term, the use of such technology in water treatment tanks will have implications for the coating products we specify for clients, particularly in terms of chemical and abrasion resistance”.

CSC Services are sponsors of the Institute of Water Northern Area for 2016.
