Biodegradation of UV Filters in Biological Activated Carbon (BAC) Process : Biodegradation Kinetic

Journal of Korean Society of Environmental Engineers, 2014
In this study, The effects of empty bed contact time (EBCT) and water temperature on the biodegradation of 8 UV filters in biological activated carbon (BAC) process were investigated. Experiments were conducted at two water temperatures (7 and 18°C) and three EBCTs (5, 10 and 15 min).

A Study of the Distribution of a Bacterial Community in Biological-Activated Carbon (BAC) [PDF]

Journal of Life Science, 2012
The use of biological-activated carbon (BAC) processes in water treatment involves biofiltration, which maximizes the bacteria’s capabilities to remove organic matter. In this study, the distribution of the bacterial community was assessed in response to different types of BAC processes applied downstream in the Nakdong River. The bacterial biomass and
