Membrane biofouling mechanism in an aerobic granular reactor degrading 4-chlorophenol.
The membrane fouling of an aerobic granular reactor coupled with a submerged membrane in a sequencing batch reactor (SBR) was evaluated. The fouling analysis was performed by applying microscopy techniques to determine the morphology and structure of the fouling layer on a polyvinylidene fluoride membrane. It was found that the main cause of fouling was the polysaccharide adsorption on the memb...
متن کامل4-Chlorophenol degradation by a bacterial consortium: development of a granular activated carbon bio®lm reactor
A bacterial consortium that can degrade chloroand nitrophenols has been isolated from the rhizosphere of Phragmitis communis. Degradation of 4-chlorophenol (4-CP) by a consortium attached to granular activated carbon (GAC) in a bio®lm reactor was evaluated during both open and closed modes of operation. During the operation of the bio®lm reactor, 4-CP was not detected in the column euent, bein...
متن کاملComparison of Different Advanced Oxidation Processes for Degrading 4-Chlorophenol
The removal efficiency of 4-chlorophenol with different advanced oxidation processes have been studied. Oxidation experiments were carried out using two 4-chlorophenol concentrations: 100 mg L and 250 mg L and UV generated from a KrCl excilamp with (molar ratio H2O2: 4-chlorophenol = 25:1) and without H2O2, and, with Fenton process (molar ratio H2O2:4chlorophenol of 25:1 and Fe concentration of...
متن کاملAquaNereda Aerobic Granular Sludge Technology Aerobic Granular Sludge
This advanced nutrient removal process can reduce footprint up to 75% and energy up to 50% when compared to conventional activated sludge systems. One of the defining characteristics of the granule is rapid settling which in turn allows for an increase in the biomass concentration. The granules are comprised of true biomass and do not require carriers. The layered microbial community that forms...
متن کاملSimultaneous nitritation and p-nitrophenol removal using aerobic granular biomass in a continuous airlift reactor.
The chemical and petrochemical industries produce wastewaters containing ammonium and phenolic compounds. Biological treatment of these wastewaters could be problematic due to the possible inhibitory effects exerted by phenolic compounds. The feasibility of performing simultaneous nitritation and p-nitrophenol (PNP) biodegradation using a continuous aerobic granular reactor was evaluated. A nit...
