Abstract
A study was conducted to evaluate how background organic matter found in surface waters can affect the adsorption kinetics and capacity of cis-1,2-dichloroethene. The study further addressed how ozone/biofilter and anion exchange pretreatment improves the performance of the GAC columns, and the ability of GAC columns to attenuate shock loadings. The results showed that the carbon's capacity for cis-1,2-dichloroethene was reduced with time of preloading. In some cases, the reduction in capacity was found even when it was determined that no total organic carbon (TOC) preloaded onto the carbon. Work with different carbon particle sizes showed that the capacity reductions were not related to the diffusion of organic matter as measured by TOC. The ozone/biofilter and anion exchange pretreatment columns increased the GAC columns operation time and increased its ability to attenuate shock loadings.
