milk ultrafiltration is a membrane process, which is highly complex innature. the cost effectiveness of the process depends heavily on the flux permeate and the total hydraulic resistance of the membrane. in this work, a comparative study for the prediction of the performance of milk ultrafiltration with ann and statistical method has been carried out. the result reveals that both methods carry...

Cross-flow ultrafiltration of macromolecular solutions in a module with microchannels is expected to have the advantages of fast diffusion from the membrane surface and a high ratio of membrane surface area to feed liquid volume. Cross-flow ultrafiltration modules with microchannels are expected to be used for separation and refining and as membrane reactors in microchemical processes. Though t...

We report our experience with Gnathostoma protein preparation by the ultrafiltration method. Crude antigen was sonicated and ultrafiltrated using the Nanosep 100 K membrane. SDS-PAGE electrophoresis showed protein bands at 43, 41, 24, 22, 21, 19.5 kDa. Use of the ultrafiltration method can provide specific protein (24 kDa), similar to the non-ultrafiltration method, with the other 5 non-specifi...

Modified ultrafiltration (MUF) has been widely used for the removal of extracellular water in the immediate postcardiopulmonary bypass (CPB) period. The reported benefits of this technique are improved hematological status and hemodynamic stability post-CPB, as well as a decrease in blood utilization during the operation. MUF has also been associated with improved pulmonary status along with en...

Diafiltration is an ultrafiltration membrane technique for completely removing, replacing, or lowering the concentration of salts or solvents from solutions containing proteins, peptides, nucleic acids, and other biomolecules. The process selectively uses permeable (porous) membrane filters to separate the components of solutions and suspensions based on their molecular size. Smaller molecules ...

the membrane separation technology by relying on microfiltration ultrafiltration, and reverse osmosis methods are becoming more important among consulting engineers, designers of environmental pollution control system, and industrial factories. the advantages of this technology together with its emphasis on recycling the fluid to the system and reusing the membranes have caused the membranes to...

Fouling has become the main problem in long-term application of ultrafiltration (UF) membrane for water and wastewater treatment, significantly reducing productivity. In this paper, fouling on polysulfone-based was analyzed using Hermia’s model during textile treatment. The UF been prepared by blending polysulfone (PSf), acetone, PEG400 DMAc, with ZnO nanoparticles at a concentration 1% weight ...

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...

The use of ultrafiltration technology for municipal drinking water applications is a relatively recent concept, although in the beginning, it is already commonly used in many industrial applications such as food or pharmaceutical industries. Ultrafiltration is proven to be a competitive treatment compare with conventional ones. In some cases, the combination of ultrafiltration with conventional...
