Biocatalytic membrane reactors (BMR) combining reaction and separation within the same unit have many advantages over conventional reactor designs. Ceramic membranes are an attractive alternative to polymeric membranes in membrane biotechnology due to their high chemical, thermal and mechanical resistance. Another important use is their potential application in a biphasic membrane system, where...

A palladium composite membrane was prepared via electroless plating technique using organic-inorganic method during activation process. The ceramic support surface was modified by two TiO2-boehmite and one γ-alumina layers to avoid Pd penetration in support pores. Thin and defect-free Pd composite membrane was obtained by creating a relative smoothness on the ceramic support and using Pd nanopa...

This work deals with modeling and simulation of SO2 removal in a ceramic membrane by means of FEM. A mass transfer model was developed to predict the performance of SO2 absorption in a chemical solvent. The model was based on solving conservation equations for gas component in the membrane. Computational fluid dynamics (CFD) of mass and momentum were used to solve the model equations. The simul...

In the area of waste water treatment, membrane processes are often used in combination with other processes to treat very complex effluents which have often an important load of organic substances and salt. The membrane process would enhance the water treaded quality in order to water reuse [1]. Membrane can be in polymer or in inorganic material. Ceramic membranes have several advantages compa...

Fouling due to biofilms composed primarily of microorganisms and extracellular polymeric substances is a significant hindrance to membrane filtration in water treatment. The goal of this work was to use a reactive membrane surface to reduce membrane biofouling by coating a ceramic ultrafiltration membrane with the nanoparticulate photocatalyst, TiO2. 10-Day biofilm growth experiments were condu...

A solid state method of NafionV/ceramic nanocomposite membrane preparation is described. A nanocomposite powder from Nafion pellets and a zirconium phosphate ceramic is formed by mechanical milling. The nanoparticles are then consolidated into membrane form by mechanical pressing. Cross-sectional analysis by scanning electron microscopy indicates that the ceramic particles exist in agglomerates...

This paper is devoted to the application of new low cost ceramic ultrafi ltration membranes material coming from the Tunisian ores (mud) which is usually considered as disastrous for the environment. A ceramic tubular support previously elaborated from mud was coated in the lumen side by slip casting method. After sintering at 650°C, the coated membrane shows homogeneou...

Ceramic membranes are considered as alternatives for their polymeric counterparts due to highmechanical strength and thermal resistance; thus long lifetime. Usually, asymmetric ceramicmembranes are synthesized including several layers with different pore size distributionswith the top-layer playing the main separation role. Titania has several properties such asphotocatalytic activity and chemi...

In this work, poly (ether-block-amide) (PEBA)/ceramic hollow fiber (HF) composite membranes with high flux were prepared by dip-coating the ceramic hollow fiber with PEBA polymer solution for pervaporation (PV). The membrane fabrication was optimized by finely tailoring the coating parameters such as the viscosity and concentration of PEBA coating solution, which made the pervaporation flux as ...
