Abstract (sommario):

Reverse osmosis (RO) desalination is a method of producing fresh water from seawater by a process similar to filtration, rather than by traditional evaporative distillation. A semipermeable membrane allows water molecules to pass through while blocking the passage of most other ions. The qualities of RO which make it attractive for naval and marine applications are its ability to operate on electric power alone, requiring no heat source; its comparatively low system weight to other methods of freshwater production at sea; and its ability to operate automatically, requiring minimal operator attention. RO's high operational reliability has contributed to its gain in popularity in recent years. RO is used for freshwater production in commercial industry and surface ship applications worldwide. The following research paper discusses RO desalination and presents RO as an alternative to conventional distillation for naval and marine use.

Abstract (sommario):

Membrane biofouling is a major concern in water treatment processes as it can significantly reduce the system’s efficiency. Biofouling is mainly caused by microorganisms, and is difficult to control or avoid. It leads to higher operating pressure which strains the membrane, shortens the membrane life, and increases maintenance costs. Multiple literature reviews suggest that the main contributors to membrane biofouling are polysaccharides. This is why in this project two model polysaccharides (alginate and xanthan) were used to study their individual fouling effects on reverse osmosis efficiency, as well as their fouling effects coupled with calcium chloride on the same system’s efficiency. During experiments, the polysaccharides were used in 0.2g/L concentrations, while calcium chloride was used at a concentration of 1.3mM. Because alginate and xanthan are two different types of polysaccharides, they would be expected to have different physical and chemical properties and thus have different fouling behaviours. It was found that the polysaccharides did not have much effect on the system’s efficiency in the absence of calcium chloride. In experiments where calcium chloride was added in the feed solution with the polysaccharide, it was demonstrated that the addition of salt led to increased membrane fouling and greater decreases in system efficiency. The fouled membranes were kept for confocal laser scanning microscopy of the fouling layers. The images determined the general structure of the cake formed on the membrane. Using the Imaris software, calculations on the average volume the cake layer was occupying (bio-volume) and the average compactness of the cake layer could be done. During experiments, the membrane showed good salt rejections with over 96% salt rejection for each experiment

Abstract (sommario):

Reverse Osmosis (RO) is a water purification technology that uses a semi-permeable membrane to remove salt and other particles from drinking water. It is the dominant technology which has overtaken many conventional systems in recent years. Membrane biofouling is the main disadvantage of using RO technology which can result in reducing the system’s efficiency. The rejected microorganisms on the surface of the membrane form a fouling layer (biofouling) which leads to a decline in permeate flux, increase of hydraulic resistance, increase in operating pressure, and shortening of the membrane life. Polysaccharides, produced by microorganisms, are the main substances responsible for membrane biofouling. In this study, two types of polysaccharides (alginate and pullulan) were used to investigate their individual fouling effects as well as their fouling effects coupled with sodium chloride and calcium chloride. 50 mM of ionic strength (27.5 g NaCl + 1.47 g CaCl2) and 0.2 g/L of polysaccharides were used in the fouling experiments conducted with a laboratory-scale reverse osmosis system. It was found that alginate lead to more reduction in system’s efficiency in comparison with pullulan. The effect of alginate on the efficiency of the system was much more severe in the presence of salt, namely sodium chloride and calcium chloride, compared to its individual effect in the absence of salt. The addition of salt led to an increase in membrane fouling and a decrease in system’s efficiency. On the other hand, it was found that pullulan enhanced the system’s efficiency when it is combined with salt. To support the above findings, a Confocal Laser Scanning Microscopy (CLSM) analysis, a Total Organic Carbon (TOC) test, and an estimation of the weight of produced fouling layers were performed. In general, analysing the results of the tests supported the findings.

Abstract (sommario):

The optimization of a reverse osmosis (RO) system includes optimization of the design of the individual membrane modules, the system structure and the operating conditions of the system. Most previous studies considered either the optimal design of individual modules only or optimization of system structure and operating conditions for fixed module dimensions. This thesis developed a method to simultaneously optimize the module dimensions, system structure and operating conditions. The method comprised rules for generating a general superstructure for an RO system given the number of modules along with rules for generating technically and mathematically feasible sub-structures. The superstructure was based on maximum connectivity between unit operations. A connectivity matrix was used to represent the superstructure. The matrix was useful for checking sub-structure's feasibility and deriving a model for the sub-structure's optimization, comprising the minimum number of variables and constraints which minimized computational time and increased accuracy. For optimization, a nonlinear objective function of the annualized profit of the RO system was formulated, consisting of the revenue obtained from permeate sales, capital costs of the unit operations and operating costs for the system. It was found that RO system optimization is a nonconvex optimization problem. The most effective optimization procedure involved a combination of evolutionary computation, which was good for locating the global optimum, and a gradient-based method, which was superior in finding the exact optimum. Small population size, adaptive mutation rate and steady state replacement were the most efficient parameter settings for the evolutionary computation. Optimal design of two-stage RO systems with and without energy recovery, bypass and recycle streams was studied. Dimensions of predicted optimal modules approached those of current commercial modules but with much shorter feed channels. The mathematical optimum also had higher operating pressures. The optimum system structure was a series arrangement with different module dimensions in each stage. A sensitivity analysis showed that trends in the optimal design were similar when unit costs changed. An investigation of the scalability of the method for a three-stage RO system revealed several weaknesses. These are probably surmountable with the addition of more RO system specific knowledge.

Abstract (sommario):

L'osmose inverse (OI) est actuellement le procédé le plus utilisé mondialement pour le dessalement des eaux saumâtres et de l’eau de mer. Cette thèse s'est intéressée à la simulation moléculaire de membranes d'OI afin d'améliorer la compréhension des propriétés structurales, dynamiques et de transport de l'eau et d'ions à l'intérieur de ces matériaux. La membrane d'OI étudiée dans ce travail est une membrane de polyamide aromatique, matériau le plus utilisé actuellement en OI. Dans la première partie de ce travail, une méthodologie a été développée pour construire un modèle atomique en trois dimensions d'une membrane polyamide fortement réticulé. Des simulations de dynamique moléculaire à l’équilibre (EMD) et hors-équilibre (NEMD) ont été réalisées pour étudier le comportement de l'eau et des ions Na+ et Cl- à travers la membrane. Les simulations EMD ont montré que les caractéristiques structurales de la membrane modèle étaient en bon accord avec celles d'une membrane typique d'OI. Les propriétés dynamiques et diélectriques de l'eau confinée dans la membrane ont également été étudiées et il a été montré que celles-ci étaient fortement modifiées par rapport à une phase volumique. Deux types de techniques NEMD ont été utilisés pour étudier le transport baromembranaire à travers la membrane modèle. La perméabilité à l'eau pure a été trouvée en très bon accord avec les données expérimentales rapportées dans la littérature et les deux méthodes NEMD ont révélé une très forte rétention saline, confirmant ainsi la pertinence du modèle de membrane d'OI développé dans ce travail
Reverse osmosis (RO) is currently the leading process used worldwide for both brackish and seawater desalination. This thesis focuses on the molecular simulation of RO membranes in order to improve the understanding of structure, dynamics and transport of water and ions inside these materials. The RO membrane studied in this work is a typical polyamide RO membrane. In the first step of this work, a methodology for building a fully atomic and three-dimensional model of a highly cross-linked polyamide membrane was developed. Both equilibrium molecular dynamics (EMD) and non-equilibrium molecular dynamics (NEMD) simulations were further performed to investigate the behavior of water and ions (Na+ and Cl-) through the membrane. EMD simulations showed that the structural characteristics of the model polyamide membrane were in good agreement with those of a typical RO membrane. The dynamics and dielectric properties of water confined in the RO membrane were also studied and have shown to be dramatically modified with respect to the bulk phase. Two types of NEMD techniques were employed to investigate pressure-driven transport through the model membrane. Pure water permeability was found to be in very good agreement with experimental data reported in the literature for similar membrane materials and both NEMD methods highlighted very high salt rejection properties, thus confirming the relevance of the model membrane developed in this work

Abstract (sommario):

Membrane separation processes, including forward osmosis (FO) and reverse osmosis (RO), for application in water desalination are plagued by membrane fouling. In particular, membrane biofouling is unpredictable in its nature and affected by numerous factors. One of the major contributors to biofouling is the extracellular polymeric substances (EPS) produced by bacteria, especially the polysaccharides that form a large part of EPS. The objectives of this study are to understand the polysaccharide fouling mechanisms based on a comparison of polysaccharide fouling in FO and RO and to find suitable alleviating agents for polysaccharide fouling mitigation. Three major tasks were conducted in this study. Firstly, polysaccharide fouling in FO and RO were compared under identical solution chemistry and operational conditions to understand the respective fouling mechanisms in FO and RO. Secondly, some alleviating agents for mitigation of polysaccharide fouling in FO and RO were tested to demonstrate the fouling alleviation mechanism. Thirdly, a model of hydraulic resistances was developed to illustrate membrane fouling mechanisms based on analysis of the contribution of hydraulic resistances to permeate flux decline. Major findings are: 1) Commercial polysaccharides and polysaccharides isolated from naturally adherent bacteria behaved differently in membrane fouling, which showed that alginate was not a typical model and it is important to select a proper model for polysaccharide fouling. 2) Under identical conditions, membrane fouling by both commercial and isolated polysaccharides was more severe in RO than FO, indicating the importance of pressure source in membrane fouling. 3) RO fouling was likely dominated by foulant – foulant interaction which was greatly affected by calcium ions, while FO fouling could be largely governed by foulant – membrane interaction, which was greatly influenced by solution viscosity. 4) Sodium nitroprusside (SNP) at a proper dose was found to be able to reduce membrane fouling, which could be explained by the electrostatic repulsion between polysaccharides and SNP. 5)Presence of calcium ions played a crucial role in polysaccharide fouling and its alleviation, with its presence leading to significant increase in cake resistance in RO fouling and reducing alleviation efficiency.

Abstract (sommario):

Thin film composite (TFC) membranes were developed for reverse osmosis (RO) under low pressure. Three commercial membranes, i.e. one type of polyvinylidene fluoride, namely AP-10, and two types of polyethersulfone, namely HW-18 and E-500, were used as substrate membranes. Sulfonated poly(2,6-dimethyl-1,4-phenyleneoxide), known as SPPO, was used as the ultrathin barrier layer of the composite membranes. The performances of the three substrate membranes were compared. The pore size and the pore size distribution of the substrate membranes were studied. Then the RO performances of the substrate membranes coated with SPPO were compared. It was observed that a high electrolyte separation without scarification of permeate flux was attained when membrane E-500 was used as the substrate membrane. Afterwards, the effects of the number of coating layers and the coating solution concentrations on RO performance of the TFC membranes, using E-500 membrane as the substrate membrane, were studied. The optimum coating solution concentration and the number of coating layers for maximum electrolyte separation were determined. The TFC membrane was then subjected to post-treatments, i.e. annealing and heat treatment under water, to improve the permeate flux. The final post-treated TFC membrane performance was concluded to be close to the targeted value.

Abstract (sommario):

A comparison of fouling in osmotically driven processes with that in pressure driven processes is the main focus of the thesis. Forward osmosis (FO) and reverse osmosis (RO) have received considerable attention for water treatment and seawater desalination. This research compared the nature of fouling in FO mode with that in RO starting with the same initial flux in connection with cleaning effects and then comparing to those in ultrafiltration membranes. In all cases, with cleaning as an integral part, the extent of fouling reversibility, and the question whether a critical flux could be determined were examined. The work during the first phase (undertaken at Oxford) quantified the removal of reversible fouling through rinsing by cold and hot water for a range of concentrations using the foulants dextran and carboxymethyl cellulose. The flux-TMP relationship was conventionally compared to that of the clean water flux. The later phase (at Singapore) compared the fouling in FO and RO by alginate in terms of multiple parameters using cellulose tri acetate (CTA) and thin film composite (TFC) membranes. Silica and alginate were selected as model foulants. Whilst experimental water flux profiles in the present study did not exhibit significant differences in trend between FO and RO fouling, foulant resistance for FO was found to be increasingly greater than for RO with the progression of the fouling tests. This was further corroborated by membrane autopsies post fouling tests; both foulant mass deposition density and specific foulant resistance for FO were greater than for RO. The analysis clearly revealed that FO is essentially more prone to fouling than RO which was presumably due to less flux decline in FO (or greater average flux) as compared to that in RO in result of ICP-self compensation effect which is opposite to the prevailing claim in the literature. Additionally, the present study did not find evidence that hydraulic pressure in RO has a role in foulant layer compaction. FO membrane fouling by real waters was the focus of the final phase of the research at SMTC. Pilot scale FO experiments were conducted on spiral wound CTA membrane with treated waste water obtained from a NEWater factory (Singapore) as the feed. In the second stage, experiments were repeated at bench scale with membrane coupons taken from the spiral wound membranes used earlier. The key finding was that the mass transfer coefficients in the Spiral-Wound module were around 50% lower than the corresponding values in the flat sheet unit and this severely limited the fluxes. The reason could be attributed to strong internal concentration polarisation in the former, where tightly wound spacers act to increase the structural parameter.

Abstract (sommario):

This paper presents a concept for desalination by reverse osmosis (RO) using a vapor-trapping membrane. The membrane is composed of hydrophobic nanopores and separates the feed salt water and the fresh water (permeate) side. The feed water is vaporized by applied pressure and the water vapor condenses on the permeate side accompanied by recovery of latent heat. A probabilistic model was developed for transport of water vapor inside the nanopores, which predicted 3–5 times larger mass flux than conventional RO membranes at temperatures in the range of 30–50°C. An experimental method to realize short and hydrophobic nanopores is presented. Gold was deposited at the entrance of alumina pores followed by modification using an alkanethiol self-assembled monolayer. The membranes were tested for defective or leaking pores using a calcium ion indicator (Fluo-4). This method revealed the existence of defect-free areas in the 100–200 μm size range that are sufficient for flux measurement. Finally, a microfluidic flow cell was created for characterizing the transport properties of the fabricated membranes.

Abstract (sommario):

In this paper, different strategies are investigated for the digital control of a reverse osmosis (RO) plant. Three control strategies to improve the performance of the RO plant are considered. These strategies including state-feeback, observer-based feedback and tracking control are considered. Simulation results show that the tracking controller yields the best perfoamnce, however it requires field knowledge about the RO plant operation. In this regard, observer-based feedback controller provides an alternative compromise.
