Assessment of GACs sampled from filters at WTWs


Nov ’06 to Mar ‘07

Granular Activated Carbon (GAC) filtration has extensive applications for the removal of organic pollutants present in drinking water. Samples of GAC were taken from a number of filters that were recently installed at two Water Treatment Works (WTW), Loftsome Bridge and Haisthorpe for GAC quality assessment.

WatStech Ltd have assessed the physical and adsorptive characteristics using the RapStech® GAC quality service. This provided the water company with independent GAC quality data for recently installed or commissioned GAC filters.
