- The removal of natural organic matter (NOM) on biological activated carbon depends on the amount of biodegradable organic carbon (BDOC) forming upon ozonation of water. The ozonation by-products described as BDOC consist of specific organic compounds (aldehydes, ketones, organic acids) and unknown assimilable organic carbon. The purpose of the study presented in this paper was to evaluate the effect of ozonation parameters (ozone dose and contact time) on the NOM characteristics measured by size exclusion chromatography, on the main ozonation by-products, aldehydes and ketones, determined by gas-chromatography and organic acids measured by ion chromatography. Experiments were performed with the ground water after iron and manganese removal, still containing comparatively high amounts of total organic carbon. Changes in molecular weight characteristics show that all the investigated NOM fractions reacted with ozone. The most reactive was the fraction of the highest molecular weight. The sum of organic acids was ten times as high as the sum of aldehydes and ketones. The amount of ozonation by-products highly depended on the ozone dose, whereas the contact time had a minor effect.
