Bacterial TOC Removal on Sand and GAC
Publication: Journal of Environmental Engineering
Volume 110, Issue 3
Abstract
A method is developed to separate the effects of adsorption and biodegradation in long term total organic carbon (TOC) removal observed on GAC contactors. TOC removal is compared on parallel sand and GAC contactors. Temperature control is used to manipulate bacterial TOC removal on the contactors. TOC mass removal curves are used to statistically compare the removal efficiencies on the four contactors. The effects of temperature on TOC removal are not significantly different on sand or GAC. This indicates that the rates of bacterial removal on sand and GAC are similar. Therefore, enhanced biodegradation does not appear to occur on GAC contactors at the low organic carbon concentrations normally encountered in potable water treatment.
