Abstract

This article evaluates the capacity of slow sand filters to remove natural organic matter (NOM) and organic precursor materials as quanitified by dissolved organic carbon, UV absorbance, and trihalomethane formation potential. Three US municipal treatment plants were sampled to provide baseline data and to evaluate the effects of two different filter cleaning techniques, normal scraping and harrowing, on NOM and particulate removal. Pilot-scale filters studies were conducted to evaluate the influence of two different flow rates on NOM removal, particulate removal, and filter biomass development.
