Hydrotreating Catalytic Processes for Oxygen Removal in the Upgrading of Bio-Oils and Bio-Chemicals

preparation and characterization of a high antibiofouling ultrafiltration pes membrane using ocmcs-fe3o4 for application in mbr treating wastewater

an innovative method based on the membrane bioreactor (mbr) technology was developed as a potential remedy for the water shortage. mbrs attracted much attention in the field of wastewater treatment and reuse. it is reported from many researchers that membrane bioreactor technology is feasible and an efficient method for the treatment of wastewater. however, mbrs are faced to membrane fouling whic...

Preparation and characterization of Montmorillonite/ZrO2 nanocomposite and its application for removal of Congo red

Montmorillonite/ZrO2 nanocomposites were prepared by the sol-gel method underultrasonic irradiation. The montmorillonite was incorporated into Zirconium gel. After stirring for 24 hr, the mixture was irradiated for 30 min under ultrasonic irradiation. The filtrated composite gel was calcinated at 400°C for 3h in furnace. The morphology of prepared catalysts was characterized by field emis...

Photocatalysts in Polysulfone Membrane for the Removal of Humic Acid: The Effects of PVP and PVA on Membrane Morphology, Separation Performance and Catalytic Hindrance

Photocatalytic membranes exhibit great potential for water treatment since they combine the filtration and photo degradation in a single unit. Although blending photocatalytic nanoparticles into polymeric thin film remains the simplest method to prepare the photocatalytic membrane, the entrapped photocatalyst showed less catalytic activity due to the agglomeration and shielding effects in the p...
