Book excerpt: Over the last decade polymeric membranes have emerged as an economically viable treatment option to produce drinking water. Due to higher capital costs, the use of ceramic membranes has generally been limited to industrial applications that deal with challenging water quality. Ceramic membranes are superior to polymeric membranes in their physical and chemical resistance, which allows for higher fluxes and backwash pressures as well as rigorous chemical cleaning. As a result, these membranes can potentially operate for longer periods of time, which can decrease the lifetime cost of the membrane. Furthermore, decreased production costs coupled with an increased desire for economical sustainability may open the door for the use of ceramic membranes in drinking water treatment, particularly for highly polluted waters. The loss of membrane permeability as a result of fouling remains one of the biggest challenges for sustainable membrane operation. Therefore, a thorough understanding of fouling behavior and the identification of key foulants is essential for optimizing membrane performance. However, fouling has not been researched in detail for ceramic membranes in drinking water treatment, particularly ultrafiltration, since most research has focused on ceramic microfiltration membranes combined with coagulation. The thesis is divided into four main stages. The first stage involved developing a factorial design to establish a procedure to determine sustainable flux that can adequately compare the fouling between a ceramic and polymeric membrane without compromising the functional potential or operating parameters of either membrane. In this stage, the significance of three different variables (interval length, increment increase, and a hydraulic backwash) in determining sustainable flux were statistically analyzed following a factorial design and consequently included or removed from the sustainable flux determination approach. The increment increase was not significant while the backwash was the most significant variable. The method established was used in later experiments to allow for a comparison of fouling behavior and performance between a polymeric and ceramic membrane. The second stage investigated the fouling behavior of flat-sheet ceramic membranes with model solutions at constant pressure to identify foulants of concern and likely fouling mechanisms for ceramic membranes as well as perform surface characterization techniques not possible with tubular membranes. In this stage the contributions of different model foulants (bovine serum albumin i.e. a protein, alginate i.e. a carbohydrate, humic acid, and colloidal silica) to reversible and irreversible fouling on a flat-sheet ceramic membrane at constant pressure were quantitatively evaluated. Both single foulant solutions and all possible combinations of mixtures of model foulants were investigated. The bovine serum albumin and humic acid were main contributors to hydraulically irreversible fouling and their removal mechanism is postulated to be largely through adsorption. Colloidal silica was the most influential factor governing fouling behavior and diminished the irreversible fouling effect of these organics, thus increasing hydraulic reversibility. Additionally, synergistic fouling effects were also observed. The third stage investigated the same model solutions with tubular ceramic membranes at constant flux to determine the fouling behavior under different conditions and quantitatively assess the effectiveness of different fouling mitigation techniques. The rate of fouling was very high for bovine serum albumin but extremely low for humic acid; however, they both showed high irreversible fouling. The results obtained were consistent with the previous stage using flat-sheet ceramic membranes; particularly regarding the significant role colloidal silica plays in fouling. The ability to compare these two very different configurations and operating parameters is largely due to the use of a hydraulic backwash in both configurations. Therefore, this highlights the importance of investigating fouling reversibility, especially in simplified experiments. The last stage investigated tubular ceramic fouling behavior and organic matter rejection with surface water at constant flux. Tubular ceramic membrane fouling behavior was investigated for river water. A very high initial organic carbon removal was observed at the initial stages of filtration and after each backwash cycle indicating a high affinity of organics to the membrane surface as well as partially reversible adsorption. Humic acid rejection decreased throughout the filtration cycle. On the contrary, biopolymer rejection remained constant indicating size exclusion as a primary removal mechanism. After several modifications to the design and setup, the sustainable flux method established in Stage 1 could not be applied to the ceramic membrane or to the polymeric membrane using highly turbid water; a few hypotheses were made as to why this occurred. It is likely that one or more variables that were not included in the sustainable flux method were influencing the fouling rate over time. Overall, the robustness of ceramic membranes opens the door for some creative fouling mitigation techniques to be used such as backwash pulses and chemical maintenance cleaning.

Book excerpt: Ceramic membrane processes are a rapidly emerging technology for water treatment, yet virtually no information on the performance and fouling mechanisms is available to the industry. Ceramic microfiltration of model feed solutions and a synthetic river water was examined, and a systematic comparison with polymeric counterpart was performed. The results suggested that the models which have been applied to polymeric membranes agreed well with the ceramic membrane filtration data. The fouling was characterized by the initial pore blocking mechanism and transition to the cake filtration mechanism at a later phase. Cake resistance was dominant and readily removable by physical cleaning. The effects of solution chemistry including ionic strength, divalent ion concentration and pH on the flux behavior were comparatively evaluated for ceramic and polymeric ultrafiltration of synthetic water containing model natural organic matter. Experimental evaluations further included resistance-in-series model analysis, organic matter fouling visualization using quantum dots, batch adsorption test, and contact angle measurement, and provided a quantitative a quantitative comparison of fouling characteristics between ceramic and polymeric membranes. The results collectively suggested that the effects of solution chemistry on the fouling behavior with ceramic membranes were mostly similar with polymeric membranes in terms of trends, while the extents varied depending on water quality parameters. Less fouling tendency and better cleaning efficiency were observed with the ceramic membranes, which was a promising finding for ceramic membrane application to surface water treatment. The study further examined a coagulation-ceramic membrane process as a robust option for surface water treatment. The performance of the hybrid system was evaluated using selected surface waters by varying coagulation conditions and types of coagulants. Results suggested that ceramic membranes experienced relatively less fouling and had better cleaning efficiency than polymeric counterpart. The results of this study provide critical information to guide the industry practitioners, consultants, and regulatory agents considering early adoption of this new technology as well as fundamental knowledge upon which further in-depth studies can be built.

Book excerpt: This book is written as a reference on organic substances in natural waters and as a supplementary text for graduate students in water chemistry. The chapters address five topics: amount, origin, nature, geochemistry, and characterization of organic carbon. Of these topics, the main themes are the amount and nature of dissolved organic carbon in natural waters (mainly fresh water, although seawater is briefly discussed). It is hoped that the reader is familiar with organic chemistry, but it is not necessary. The first part of the book is a general overview of the amount and general nature of dissolved organic carbon. Over the past 10 years there has been an exponential increase in knowledge on organic substances in water, which is the result of money directed toward the research of organic compounds, of new methods of analysis (such as gas chromatography and mass spectrometry), and most importantly, the result of more people working in this field. Because of this exponential increase in knowledge, there is a need to pull together and summarize the data that has accumulated from many disciplines over the last decade.

Available in PDF, EPUB and Kindle. Book excerpt: Abstract: Ultrasound at a frequency of 20 kHz and a power of 16 W was applied to a cross-flow ultrafiltration system to investigate the ultrasonic control of surface-water fouled ceramic membranes. Also, the impact of solution chemistry on fouling in the absence and presence of ultrasound was studied. Ultrasound was effective in improving the normalized permeate flux from 0.21 in the absence of ultrasound to 0.70 with the aid of ultrasound. Moreover, a stable permeate flux was obtained throughout the 2 hour filtration process, which is important for maintaining satisfactory production. Parameters of solution chemistry we investigated had little impact on membrane fouling in the absence of ultrasound (in terms of both fouling rate and fouling extent); however, Ca and pH played more important roles in ultrasonic fouling control: lower calcium concentration and moderate pH values were more amenable to ultrasonic control. This difference in fouling behavior between ultrasound and no ultrasound conditions was attributed to the different factors controlling membrane fouling in the presence and absence of ultrasound. Further investigation of NOM fractions suggests that the hydrophilic fraction dominated fouling behavior in the absence of ultrasound, and the ultrasonic control was mainly affected by foulant-foulant and foulant-membrane interactions, which were presumably controlled by the adsorption or binding effects in the hydrophobic fraction. NOM fractionation experiments revealed that fouling in the absence of ultrasound by the hydrophilic fraction was less dependent on calcium concentration and pH. On the other hand, for ultrasonic control, lower calcium concentration, and moderate pH increased the cleaning efficiency probably due to weaker foulant-foulant and foulant-membrane adhesion caused by less humic adsorption and binding effects.

This book was released on 2018 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Ultrafiltration fouling in drinking water treatment has been primarily attributed to the biopolymer fraction (e.g., proteins) of organic matter in source waters. This bench-scale study examined the use of coagulation to mitigate fouling in three model protein solutions. Similar to results from studies conducted with natural waters, a low coagulant dose (2 μM Al) was identified to significantly reduce membrane fouling relative to zero coagulant addition for two proteins (BSA and ovalbumin). It is hypothesized that the low dosages alter the surface hydrophobicity of proteins in both the bulk solution and fouling layer, resulting in weakened intermolecular interactions, reducing fouling. The impacts of applying coagulation only during the initial stages of a permeation cycle (phased coagulation) on membrane fouling were investigated at pilot-scale. Coagulant application during the first half of the cycle resulted in fouling rates similar to that of continuous addition, which could translate to significant cost savings.

This book was released on 2014 with total page 62 pages. Available in PDF, EPUB and Kindle. Book excerpt: Over the past few decades, membrane processes has received overwhelming attention worldwide in drinkable water production offering advantages such as compact module, lower energy consumption, environmental friendliness and high quality of water product which is independently on the fluctuations in feed quality. Among those methods, ultrafiltration membrane process has receives the most attention publicly. Ultrafiltration (UF) membrane technology is a low pressure driven membrane separation process aimed to recover water from a saline solution pressurized to a point greater than the osmotic pressure of the solution. In essence, this membrane can filters viruses and microorganisms under low applied pressure and create high permeate flux. These will save a lot of cost as the process only consume little energy. However, for this successful application, the major critical issue is fouling. The major foulants come from the natural organic matters (NOM) where it is mainly in the river water. This NOM consists of humic acid where it is the main fouling factor to the UF membrane. Humic acid will cause pore blockage or cake formation on the membrane that will further decrease the permeate flux of the filtered water. In spite of that, there are also many fouling factor that increase the fouling index of humic acid on UF membrane such as trans-membrane pressure and pH of the feed solution which represent the feed characteristic and the operation parameter that will probably contribute to the fouling index of the membrane. Therefore, a study will be done on parameters, pH of the feed solution and addition of calcium ion in order to investigate the fouling index of humic acid on membrane. The experiments start with the pure water permeability test with different pressure. Then, the fouling experiments wil start with filtration of humic acid solution with different pH, 3, 6 and 9. The fouling index, flux and solute rejection has been studied. The result obtained showed that permeate flux was lower whenever the pH of humic acid solution was lowered due to fouling in contraty the flux was higher when the pH is high. This phenomenon showed that membrane is easier to foul when the pH is low. Besides that, since the flux was decrease, which means the membrane was fouled. Hence, the fouling index of the membrane was increased when pH was low while decreased when the pH was high. Lastly, the solute rejection is related with the fouling of the membrane. When the membrane was fouled under low pH, the rejection of the membrane was increased because the membrane pore was partially block. Adversely, the rejection of the membrane is lower under high pH as the membrane was less fouled. To achieve the desired volume, longer filtration time was taken.

This book was released on 2014 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The inherent thermal resistance of ceramic membranes allows for treatment of industrial waters at elevated temperatures. Traditionally, the high temperature of wastewater has been an issue compromising the integrity of polymeric membrane systems or requiring the temperature to be lowered for further treatments. In ceramic membrane systems, a decrease in viscosity with increasing temperature, however, can be utilized, which increases the permeate flux. In this study, the fouling of ceramic ultrafiltration by feed solutions containing colloidal silica was evaluated at temperatures between 25 - 90 °C seen in various industries. Ceramic membranes were able to perform well at elevated temperatures up to 90 oC with sustained mechanical and chemical integrity. Results showed net benefit of filtration at elevated temperatures on permeate flux in spite of increasing total fouling resistance with temperature. When the temperature increased from 25 to 90 °C, there was a 90% increase in steady-state permeate flux. The dominant resistance was physically removable fouling, and the increase in fouling with feed temperature was supported by force balance analyses. This study provides a foundation from which further studies can be developed including pilot-scale testing, use of real wastewater, and the effects of operating conditions.

This book was released on 2016 with total page 151 pages. Available in PDF, EPUB and Kindle. Book excerpt: Ceramic membranes have been widely and successfully used in the food and beverage processing industry. Despite their success, ceramic membranes are not commonly employed in drinking water treatment due to their high initial capital cost. Polymeric membranes, on the other hand, have gained widespread use in drinking water treatment in the last few decades due to their ability to meet stringent water quality regulations. Ceramic membranes have a number of advantages over polymeric membranes, which include high chemical and thermal stability, higher fluxes and longer operational life. Advances in membrane technology in recent years coupled with innovative design have made the life cycle cost of implementing ceramic membranes competitive with that of polymeric membranes. This has resulted in a number of drinking water treatment plant installing ceramic membranes as part of the treatment process, especially in Japan. The biggest challenge facing membrane filtration (polymeric or ceramic) is fouling. To control fouling, coagulation prior to ceramic membrane filtration is often implemented and has been shown to be effective in controlling both hydraulically reversible and irreversible fouling. Direct biofiltration without pretreatment (BFWP) (coined by Huck et al., 2015) has been shown to be another effective “green” pretreatment to control fouling in polymeric membranes. High molecular weight natural organic matter (NOM) such as biopolymers have been found to be directly related to the hydraulically reversible fouling and to play a key role in hydraulically irreversible fouling of polymeric membranes and biofiltration is able to reduce the concentration of this NOM fraction. Given the effectiveness of BFWP in controlling fouling in polymeric membranes, there is an opportunity to investigate its applicability to ceramic membranes. Therefore, the goals of this study were to investigate the efficacy of BFWP as a pretreatment to control fouling in ceramic membranes and characterize the fouling of the membranes over time. The effects of Empty Bed Contact Time (EBCT) of the biofilters, membrane materials and pore sizes (Microfiltration (MF) vs. Ultrafiltration (UF)) on the fouling rates were also investigated in the study.
