Project Description

Disinfection byproduct modelling

Trihalomethanes are a primary by-product of chlorination, formed by reactions between halogens and organic matter in water, particularly the humic and fulvic acids resulting from the decomposition of natural and anthropogenic organic material. Some THMs are known to be carcinogenic and consequently their presence is regulated, with a maximum permitted concentration of 100 µg/l measured at customers’ taps.

This project seeks to extend our knowledge of the formation of THMs in water supply systems (including treatment works and distribution systems).

Specifically, the project will undertake desktop, field and laboratory studies:

i. To investigate the influence of water quality parameters, initial chlorine concentration, temperature, contact time, water treatment unit and supply processes on chlorine decay, in order to develop empirically based models to relate functional dependencies to each other.

ii. To investigate THM formation in relation to key water quality parameters, initial chlorine concentration, temperature, contact time and water treatment unit and supply processes, and consequently to determine appropriate THM formation models.

iii. To consolidate the analysis into a robust, cost-effective, numerical model that can be practically applied in operational circumstances, enabling the user to enter prevailing water quality and WTW operational characteristics to predict chlorine use and THM formation from source water to customer tap.
