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...
متن کاملRemoval 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...
متن کاملOptimization of organic compounds removal from Wastewater by Electrocoagulation
Introduction: As the most hazardous sewage, hospital wastewater contains various contaminants, and its uncontrolled discharge can seriously damage the environment. Bandar Abbas is located in an arid and semi-arid region therefore, hospital wastewater should be treated through an appropriate and economic method. This study aimed to determine the efficiency of electrocoagulation with aluminum and...
متن کاملCharacteristics of adsorptive removal of 2-methylisoborneol by micro-milled activated carbon
In both research and practice of water purification technology, superfine powdered activated carbon (SPAC), which is produced from conventionally sized powdered activated carbon (PAC) by wet milling in a bead mill, has attracted attention for its higher adsorption capacity of contaminants as well as the higher adsorptive uptake speed than its parent PAC. However, the previous SPAC researches on...
متن کاملRemoval of trace organic contaminants by the forward osmosis process
The rejection of trace organic contaminants (TrOCs) by an osmotically driven membrane filtration process was investigated. A set of 40 compounds representing major groups of TrOCs of concern was selected for this study. The rejection of the TrOCs by a commercial cellulose acetate asymmetric forward osmosis membrane, as well as a ''tight'' commercial thin-film composite nanofiltration (NF) membr...
