Removal Characteristics of Micropollutant by Biological Activated Carbon.

Organic Micropollutant Removal by Biological Activated Carbon Filtration: A Review

Simultaneous activated carbon adsorption within a membrane bioreactor for an enhanced micropollutant removal.

Significant adsorption of sulfamethoxazole and carbamazepine to powdered activated carbon (PAC) was confirmed by a series of adsorption tests. In contrast, adsorption of these micropollutants to the sludge was negligible. The removal of these compounds in membrane bioreactor (MBR) was dependent on their hydrophobicity and loading as well as the PAC dosage. Sulfamethoxazole exhibited better remo...

Effect of characteristics of activated carbon on removal of bromate

This study evaluates how the characteristics of activated carbon (AC) influence the adsorption–reduction of bromate (BrO3−) by performing inetic and isotherm tests. Experimental results reveal that both physical and chemical effects simultaneously affect the adsorption–reduction rocess. The wood-based carbons contained more mesopores than coconutand coal-based carbons, resulting in the adsorpti...

Arsenic removal by iron-modified activated carbon.

Iron-impregnated activated carbons have been found to be very effective in arsenic removal. Oxyanionic arsenic species such as arsenate and arsenite adsorb at the iron oxyhydroxide surface by forming complexes with the surface sites. Our goal has been to load as much iron within the carbon pores as possible while also rendering as much of the iron to be available for sorbing arsenic. Surface ox...

Removal of high concentration of NH3 and coexistent H2S by biological activated carbon (BAC) biotrickling filter.

High efficiency of NH3 and H2S removal from waste gases was achieved by the biotrickling filter. Granular activated carbon (GAC), inoculated with Arthrobacter oxydans CH8 for NH3 removal and Pseudomonas putida CH11 for H2S removal, was used as packing material. Under conditions in which 100% H2S was removed, extensive tests to eliminate high concentrations of NH3 emission-including removal char...
