Biodegradation of Natural Estrogens by Biofilms from Biological Activated Carbon: Effect of Temperature

In order to obtain information on the biodegradation potential of biofilms involved in the removal of natural estrogens by biological activated carbon (BAC) columns, batch degradation of estrone (E1) and 17-estradiol (E2) at temperature of 5 ̊C, 20 ̊C and 35 ̊C by biofilms from four BAC columns (packed with activated carbon of particle size ranging from 0.5 0.59 mm and 1.0 1.19 mm into two bed de...

Enhancement of removal of trace organic contaminants by powdered activated carbon dosing into membrane bioreactors

This study compared the removal efficiency of 22 widespread trace organic contaminants by a laboratory-scale membrane bioreactor (MBR) with and without direct addition of powdered activated carbon (PAC) into the activated sludge reactor over a period of 312 days. The removal of hydrophilic and biologically persistent trace organic contaminants was immediately improved to above 95% after the add...

Removal of trace organic contaminants by a membrane bioreactor-granular activated carbon (MBR-GAC) system.

The removal of trace organics by a membrane bioreactor-granular activated carbon (MBR-GAC) integrated system were investigated. The results confirmed that MBR treatment can be effective for the removal of hydrophobic (log D>3.2) and readily biodegradable trace organics. The data also highlighted the limitation of MBR in removing hydrophilic and persistent compounds (e.g. carbamazepine, diclofen...
