Micropollutant removal with saturated biological activated carbon (BAC) in ozonation–BAC process
Water Science and Technology, 1997 The objective of this study is to evaluate the adsorption capacity of BAC saturated with natural organic matter (NOM) for micropollutant removal which intermittently enter into water sources and to compare this to sand filtration that has no adsorbability but has biodegradability. The removal of intermittently applied micropollutants was

Substrate Pre-loading Influences Initial Colonization of GAC Biofilter Biofilms
Frontiers in Microbiology, 2021 Microbial community composition and stability affect pollutant removal for biological/granular activated carbon (BAC/GAC) processes. Here, we pre-loaded the organic carbon substrates sucrose, lactose, and Lysogeny Broth (LB) medium onto new GAC prior to ...
