Download or read book Fouling in Polymeric Membranes Modified with Low Temperature Plasma written by Jan Johansson and published by . This book was released on 1997 with total page 500 pages. Available in PDF, EPUB and Kindle. Book excerpt: This study examines the fouling of polymeric membranes with albumin using four membranes with different hydrophilic/hydrophobic characteristics and pore structures. A radioactive tracer technique was used to study adsorption of albumin on these membranes. In the aqueous phase protein concentration range of 0-40 mg/ml, the adsorption isotherms were linear for polyvinylidene fluoride, nylon and polycarbonate membranes. Only for polypropylene membranes, was a nonlinear adsorption isotherm observed. For an aqueous phase concentration of 1 mg/ml, the most adsorption occurred on polypropylene (19.9 mg/m$\sp2)$ and polycarbonate (20.6 mg/m$\sp2)$; adsorption on PVDF and nylon were considerable less (1.44 mg/m$\sp2$ and 3.26 mg/m$\sp2,$ respectively). No effect of pore size was found in the adsorption isotherms. Fouling was characterized by the permeability of water and albumin solutions through membranes. The effect of adsorption on fouling was also quantified; a direct relation was found between the relative permeability of albumin solution and protein adsorption. A high adsorptive membrane had low relative permeability of albumin solution and a low adsorptive membrane had high relative permeability of albumin solution. For hydrophobic membranes, the high protein adsorption was responsible for low permeability of albumin solution. On the other hand, protein aggregation played a more dominant role for hydrophilic membranes. Low temperature plasma was used to modify the adsorption on the membranes. Tortuosity and thickness of membranes were important parameters for the surface modification to be effective. Protein adsorption decreased with increasing oxygen content in the feed gas for the n-butane/oxygen treatment, indicating the importance of hydrophobic interactions for albumin. For the oxygen plasma and the n-butane/oxygen plasma treatments, the protein adsorption was reduced by 96% and 73%, respectively. Correspondingly, the permeability of albumin solution increased by 91% and 89%, respectively. For practical use, the n-butane/oxygen plasma treatment may be a better alternative than oxygen plasma treatment because of the rotation of hydrophilic groups into the bulk polymer for the latter treatment. For the nitrogen and n-butane/nitrogen treatments, protein adsorption increased with increasing nitrogen content in the feedgas despite a decreasing contact angle, indicating that electrostatic interaction influenced the adsorption. The higher adsorption on the aminated membranes resulted in a reduction in relative permeability.

Download or read book Micellar Enhanced Ultrafiltration written by Sirshendu De and published by CRC Press. This book was released on 2012-06-04 with total page 227 pages. Available in PDF, EPUB and Kindle. Book excerpt: A response to increasingly stringent regulation of pollution and toxicity levels in industrial waste discharge, Micellar Enhanced Ultrafiltration: Fundamentals & Applications offers the most complete book available on the benefits and use of micellar-enhanced ultrafiltration (MEUF) to achieve continuous removal of organic and inorganic pollutants. An Unparalleled Book That Addresses Both Academic and Industrial Points of View Several membrane-based techniques, such as microfiltration, ultrafiltration, nanofiltration, and reverse osmosis, are currently used in a wide range of applications throughout the textile, pulp and paper, sugar, chemical, pharmaceutical, biomedical, biotechnological, and food industries. However, although reverse osmosis is an effective means of removing contaminants, this book explains why MEUF is a better substitute, as it less expensive, less energy-intensive, and more efficient and practical for a wider range of applications. Topics covered include: Effects of pollution in water and its consequences Various treatment processes and membrane technologies Fundamentals of ultrafiltration Outline of various membrane modules and modeling approaches Principles of colloid chemistry Theories of micelle formation Stability and dynamics of micelles Phenomena of counterion binding Solubilization of organic pollutants Selection criteria for surfactants Various flux enhancement techniques Recovery of precious metals This book conveys how, with proper selection of surfactant and membrane, MEUF can be used to efficiently remove almost all metal ions (heavy metals, lanthanides, radioactive materials, etc.) with reasonably high efficiency and throughput. It also details the MEUF process for removal of inorganic (cations, anions, and their mixture) and organic pollutants. The authors explain how the economy of the overall process makes recovery and reuse of surfactants essential, and they address various influencing factors on the increase in throughput and the resulting operating problems. Elaborating on technologies involving precipitation and other methods, they also illustrate additional potential applications for MEUF technology.
