Identification of nitrifiers and nitrification performance in drinking water biological activated carbon (BAC) filtration

Process Biochemistry, 2010
Abstract In this study laboratory scale biological activated carbon (BAC) columns were operated with water taken from a surface water reservoir in Istanbul. The aim was to evaluate the efficiency of nitrification in columns packed with two different granular activated carbon grades (open superstructure/chemically activated and closed superstructure ...

Effects of water quality changes on performance of biological activated carbon (BAC) filtration

Separation and Purification Technology, 2019
Biological activated carbon (BAC) filtration is an important treatment step in the production of drinking water especially if drinking water is produced from surface water. The performance and processes within a BAC filter have been of interest for researchers since the 1980's, mainly because of its ability to remove natural organic matter known as ...

Comparison of biological activated carbon (BAC) and membrane bioreactor (MBR) for pollutants removal in drinking water treatment

Water Science and Technology, 2009
Biological activated carbon (BAC) and membrane bioreactor (MBR) were systematically compared for the drinking water treatment from slightly polluted raw water under the same hydraulic retention time (HRT) of 0.5 h. MBR exhibited excellent turbidity removal capacity due to the separation of the membrane; while only 60% of influent turbidity was ...

Property and mechanism of phenol degradation by biochar activated persulfate

Journal of Materials Research and Technology, 2020
In this study, corn stover was used to prepare biological activated carbon (BAC). First, the calcination temperature of BAC was optimized, and the calcination rate of BAC as the activator was confirmed to be maximal when the heating rate was 5.0 °C min−1,

Biodegradation of Synthetic Fragrances in Biological Activated Carbon (BAC) Process : Biodegradation Kinetic [PDF]

Journal of Korean Society of Environmental Engineers, 2014
Abstract : In this study, The effects of empty bed contact time (EBCT) and water temperature on the biodegradation of 8 synthetic fragrances (SFs) in biological activated carbon (BAC) process were investigated. Experiments were conducted at two water tem-peratures (7 and 18℃) and three EBCTs (5, 10 and 15 min).

Evaluation of Ozonation-Biological Activated Carbon(O3-BAC) Process in Advanced Drinking Water Treatment. [PDF]

Journal of Japan Society on Water Environment, 1997
Parallel studies using Ozonation-Biological Activated Carbon (O3-BAC) process and a simple Biological Activated Carbon (BAC) process were conducted to evaluate the effect of ozonation on a BAC process. The raw water used was pre-treated by microfiltration to remove suspended solids. Contact time for ozonation was 24 minutes while empty bed contact time

Quantification of microbial degradation activities in biological activated carbon filters by reverse stable isotope labelling

AMB Express, 2019
Biological activated carbon (BAC) filters are frequently used in drinking water production for removing dissolved organic carbon (DOC) via adsorption of organic compounds and microbial degradation. However, proper methods are still missing to distinguish
