Description

Four granular activated carbon (GAC) columns (GAC-1-GAC-4) were designed by packing two types of GAC achieved by pulverizing and sieving a market-available GAC (F-400/Filtrasorb/USA) into two particle size ranges (d=0.5-0.59mm and d=1.0-1.19mm). In parallel, four biological GAC columns (BAC-1-BAC-4) were also established by coating identical GAC columns with microorganisms detached from the river bed sediment at the river water sampling site. River water containing lower content of NOM was pumped continuously into the columns to examine the behavior of NOM. Besides, 17ß-estradiol (E2) was intermittently added into the river water with/without the addition of a peat water that contains a high NOM content to investigate the removal of E2 and the responses of all columns to the influent NOM increases. The results after running for about 3000 hours showed that:(1) NOM constituents (excluding non-adsorbable ones) were well removed over the wide range of molecular weights;(2) a portion of DOC species not reflective by UV260 was removed through degradation by attached microbes; and (3) E2 was readily removed via adsorption (for GAC columns) and a combination of adsorption/biodegradation (for BAC columns), with its removals being significantly higher than those of NOM.
