Fokus ove doktorske disertacije je ispitivanje unakrsne mikrofiltracije i ultrafiltracije. Jedan od glavnih problema pri izvođenju ovih procesa je opadanje fluksa permeata tokom vremena. Svi fenomeni koji dovode do opadanja fluksa permeata obuhvaćeni su fenomenom koncentracione polarizacije i fenomenom „prljanja” membrane...

2. Satterfield, Derrick James. Mitigation and Removal of Biological Fouling in a Forward Osmosis Membrane Bioreactor.

Degree: 2019, University of Nevada – Reno

The adherence of bacteria cells, extracellular proteins and polymers, and other organic materials on membrane surfaces can negatively impact the efficiency and economic feasibility of membrane-based treatment processes for wastewaters. Forward osmosis (FO) is an emerging membrane technology that utilizes an osmotic gradient rather than hydraulic pressure as a driving force to produce clean water. Because there is not a hydraulic pressure difference across the membrane, FO has a lower fouling propensity than other membrane processes, such as reverse osmosis or ultrafiltration, and thus is well-suited for use with wastewater sources containing high organic and biological loads. This work presents in situ cleaning methods for the mitigation and removal of biological fouling on FO membranes in a submerged osmotic membrane bioreactor. A novel FO membrane module was developed that allowed for three membrane coupons to be evaluated independently under the same biological conditions. Overall water production and energy efficiency were evaluated under different osmotic backwashing temperatures, durations, and frequencies, as well as with coupled mechanical scouring. Fouling propensity, fouling removal, and water flux was also examined with antibiotic dosed and heated draw solutions. Adding antibiotics to the draw solution is proposed to reduce and or mitigate biological fouling by producing a concentrated antibiotic layer on the membrane surface. Heating up the draw solution extends previous work showing increased fluxes by introducing fouling at these elevated temperatures to determine to what extent the increased operating flux trend remains.

3. Kazemi, Amir Sadegh. Development of High-throughput Membrane Filtration Techniques for Biological and Environmental Applications.

Degree: PhD, 2018, McMaster University

Membrane filtration processes are widely utilized across different industrial sectors for biological and environmental separations. Examples of the former are sterile filtration and protein fractionation via microfiltration (MF) and ultrafiltration (UF) while drinking water treatment, tertiary treatment of wastewater, water reuse and desalination via MF, UF, nanofiltration (NF) and reverse-osmosis (RO) are examples of the latter. A common misconception is that the performance of membrane separation is solely dependent on the membrane pore size, whereas a multitude of parameters including solution conditions, solute concentration, presence of specific ions, hydrodynamic conditions, membrane structure and surface properties can significantly influence the separation performance and the membrane’s fouling propensity. The conventional approach for studying filtration performance is to use a single lab- or pilot-scale module and perform numerous experiments in a sequential manner which is both time-consuming and requires large amounts of material. Alternatively, high-throughput (HT) techniques, defined as the miniaturized version of conventional unit operations which allow for multiple experiments to be run in parallel and require a small amount of sample, can be employed. There is a growing interest in the use of HT techniques to speed up the testing and optimization of membrane-based separations. In this work, different HT screening approaches are developed and utilized for the evaluation and optimization of filtration performance using flat-sheet and hollow-fiber (HF) membranes used in biological and environmental separations. The effects of various process factors were evaluated on the separation of different biomolecules by combining a HT filtration method using flat-sheet UF membranes and design-of-experiments methods. Additionally, a novel HT platform was introduced for multi-modal (constant transmembrane pressure vs. constant flux) testing of flat-sheet membranes used in bio-separations. Furthermore, the first-ever HT modules for parallel testing of HF membranes were developed for rapid fouling tests as well as extended filtration evaluation experiments. The usefulness of the modules was demonstrated by evaluating the filtration performance of different foulants under various operating conditions as well as running surface modification experiments. The techniques described herein can be employed for rapid determination of the optimal combination of conditions that result in the best filtration performance for different membrane separation applications and thus eliminate the need to perform numerous conventional lab-scale tests. Overall, more than 250 filtration tests and 350 hydraulic permeability measurements were performed and analyzed using the HT platforms developed in this thesis.
