Book excerpt: This book titled "Microfiltration: Principle, Process and Applications" is formed of 6 chapters covering many research aspects on microfiltration. These aspects include reviews and original research dealing mainly with fouling and cleaning of microfiltration membranes. In Chapter 1, mechanisms of fouling and factors affecting the fouling are presented. Also, it deals with techniques that assist mitigation of membrane fouling that occurs in microfiltration. The aim of Chapter 2 was the modelling and optimization by artificial neural network and genetic algorithm of yeast suspensions turbulence promoter assisted cross-flow microfiltration in concentration operation mode. Chapter 3 focuses on the principles, developments, implementation and application of microfiltration in wastewater treatment. In addition, the integration of microfiltration with other water and wastewater treatment technique is also included as well as the advantages and disadvantage of the microfiltration. The Chapter 4 objective is to introduce the most commonly used turbulence promoters' types. Furthermore, congenial studies on the turbulence promoters' application in the cross-flow MF regarding food industry streams and products are also presented within the chapter. In Chapter 5, the microfiltration process was used in order to obtain concentrated papaya (Carica papaya L.) pulp, evaluating the flux permeate from papaya treated pulp with enzyme pectinase and using different nominal mass molecular weights and different membranes materials. Chapter 6 discusses the performances and the quality of treated water of a Tunisian textile industry through a low-cost tubular ceramic membrane prepared by extrusion of a plastic paste prepared from clay powder mixed with organic additives and water.

Book Synopsis Modelling and Prediction of Non-linear Scale-up from an Ultra Scale-Down Membrane Device to Process Scale Tangential Flow Filtration by : Mohd Shawkat Hussain
Download or read book Modelling and Prediction of Non-linear Scale-up from an Ultra Scale-Down Membrane Device to Process Scale Tangential Flow Filtration written by Mohd Shawkat Hussain and published by . This book was released on 2019 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Ultra scale-down (USD) tools have demonstrated the huge potential for accelerated process development by significantly reducing the material requirements and providing better solutions, as part of the Quality by Design initiative. Key benefits of using USD techniques include the relatively small quantities of feedstock and minimal capital equipment needed to generate large volumes of statistically significant process data in a short period, leading to significant time and cost savings during process development. However, the use of small scale devices such as the stirred cell filtration units have been primarily limited to preliminary testing and initial screening due to their geometric and flow dissimilarities to tangential flow filtration at scale. As a result, process development and optimisation trials are generally carried out using the smallest c commercially available TFF cassettes, the use of which are primarily limited by time and material constraints that are invariably present at the early stages of process development. Therefore, the central focus of this work was to develop a USD methodology and model to accurately predict the performance of large scale tangential flow filtration (TFF) using a USD membrane filtration device. // The commercial package COMSOL was used to carry out computational fluid dynamics (CFD) modelling and simulation of the fluid flow dynamics in Pellicon TFF cassettes with different feed screens and a USD membrane device, in order to develop average wall shear rate correlations and channel pressure drops expressed as functions of the respective hydrodynamic conditions across scales. In addition, the impact of non-TFF related factors such as the system and cassette-specific hydraulic resistances on TFF performance was characterised using semi-empirical models. Finally, a scale-up methodology and mathematical model to predict the large scale performance using USD data was developed by combining the various resistances, channel pressure drop correlations and an empirical USD-derived model that characterises the specific feed-membrane interactions. The CFD simulations were independently verified using 2D particle imaging velocimetry to compare experimental data to the CFD simulated data. // 100-fold scale-up experiments were carried out based on equivalent averaged wall shear rates (w) as the geometry-independent parameter. Permeate flux excursions were carried out to validate the USD methodology and prediction model, by comparing USD model predictions against the large scale experimental data. Different membranes, feed screens (A, C and V) and feedstock, ranging from simple proteins like Bovine Serum Albumin (BSA) to more complex, multicomponent feed such as Escherichia coli homogenate, were used. Predicted flux and transmission results were in good agreement with the large scale experimental data, showing less than 5% difference across scales, demonstrating the robustness of the non-linear scale-up model. // Following the successful validation of the scale-up methodology and prediction model, other potential applications of the USD membrane device such as the optimisation of TFF microfiltration was demonstrated using Saccharomyces cerevisae and Chlorella sorokiniana. Fed-batch concentration experiments using Saccharomyces cerevisae were done to compare the volumetric throughput limits. The USD-predicted capacity limit of 49.2 L/m2 was very similar to the experimental large scale capacity value of 52.0 L/m2, and considered fully scalable within experimental errors. Finally, fouling studies were performed using Chlorella sorokiniana and the USD device to investigate the impact of media type and growth conditions on the filtration performance. The results indicated a strong correlation between soluble fouling species, such as exopolysaccharides and carbohydrates, rather than the algal biomass. A novel, dynamic flux control methodology was developed based on empirically determined critical fluxes expressed as a function of cell concentration. The dynamic control strategy was successfully verified by performing a 50-fold concentration experiment using a hollow fibre module and the USD device. An improvement of greater than 50% in average throughput was achieved using the 3-step flux cascade compared to the traditional flux-time/capacity optimised fluxes, with no observable increase in TMP throughout. // The work presented here demonstrates the potential of ultra scale-down tools coupled with a mathematical modelling approach to establish a predictable scale-up performance, which can be used to rapidly develop and optimise tangential flow filtration processes, regardless of differences in geometry, flow configuration and system setup.

Available in PDF, EPUB and Kindle. Book excerpt: LAD, ANKIT RAGHUNATH. Flow Modeling for Micro-filtration through electro-statically charged monolith filters. (Under the direction of Dr. Andrey V. Kuznetsov.) This study is a multi-physics problem which aims at modeling fluid flow through electro-statically charged monolith filters with machined micro-channels. The multi-phase fluid (air) considered has suspended micro particles which are the impurities to be filtered out. The resulting particle trajectories due to the effect of the forces exerted on the particle such as the hydrodynamic drag, the electrostatic force of attraction and repulsion and Brownian diffusion are studied. The micro-filtration process is studied under the presence of an electric field developed due to the uniform density charge distributed over the channel surface. The model is validated by comparison with the experimental result. The advantage of using repulsive electric field instead of attractive electric field for filtration is studied. The unit cell filtration system is developed for normal and cross flow and the scope for efficiency improvement is tested. The possibility of ââ'¬Ëœselective filtrationââ'¬â"¢ is examined by using the multiple filter layer model and the role of different hole-orientation pattern is also studied. The experimental setup of the filtration system and the filter material strength for practical applications is discussed.
