Abstract:
It is of great importance to quantitatively characterize feed fouling potential for the effective and efficient prevention and control of reverse osmosis membrane fouling. A gradient filtration method with microfiltration (MF 0.45 μm) → ultrafiltration (UF 100 kDa) → nanofiltration (NF 300 Da) was proposed to extract the cake layer fouling index, I, of different feed foulants in this study. MF, UF, and NF showed high rejection of model suspended solids (kaolin), colloids (sodium alginate and bovine serum albumin), and dissolved organic matters (humic acid) during constant-pressure individual filtration tests, where the cake layer was the dominant fouling mechanism, with I showing a good linear positive correlation with the foulant concentration. MF → UF → NF gradient filtration tests of synthetic wastewater (i.e., model mixture) showed that combined models were more effective than single models to analyze membrane fouling mechanisms. For each membrane of gradient filtration, I showed a positive correlation with the targeted foulant concentration. Therefore, a quantitative assessment method based on MF → UF → NF gradient filtration, the correlation of combined fouling models, and the calculation of I would be useful for characterizing the fouling potentials of different foulants. This method was further successfully applied for characterizing the fouling potential of real wastewater (i.e., sludge supernatant from a membrane bioreactor treating dyeing and finishing wastewater).

Abstract:
Fouling of surfaces is a major challenge in design and operation of many industrial heat transfer equipment. Fouling causes significant energy, material and production losses, which increase the environmental impact and decrease economic profitability of processes. Even small improvements in prevention of fouling would lead to significant savings in a wide range of heat transfer applications. In this study, crystallization fouling of aqueous calcium carbonate solutions on a heated stainless steel surface is used to investigate the prevention of fouling in heat transfer equipment by physical surface modifications. Fouling behaviour of different surface patterns are studied experimentally in a laboratory scale fouling test apparatus. CFD modelling is used to study hydrodynamic and thermal conditions near surfaces with different patterns. In addition, the effect of surface pattern on the removal of particles is studied numerically. Surface patterning is found to affect the hydrodynamic and thermal conditions near the wall, and therefore to change the conditions for fouling layer build-up and removal, when compared to a flat heat transfer surface. The most promising surface pattern includes curved shapes, and it seems to create flow conditions in which improved convective heat transfer decreases the driving force for crystallization fouling. In addition, curved surfaces increase the shear forces at the wall, which prevents adhesion of the foulants to the surface and increases resuspension.

Abstract:
In this experiment, the effects on improve of flux and prevention of membrane from fouling was studied. The results demonstrated that after backwashing, the flux was completely recovered by addition of 4mg/L and 10mg/L（as Al）, while the flux was only 40% of initial flux without coagulation pretreatment. It was also found that whether or not prevention of fouling by coagulation was depended on the characteristics of cake layer formed on membrane surface during membrane filtration. In the presence of filtration of coagulation floc suspension, coagulation could form cake layer on membrane surface, thus prevent membrane from fouling effectively, while in the presence of filtration of supernatant, fouling was occurred due to cake layer comprising small, neutral, hydrophilic compounds, which can not removed by backwash.

Abstract:
The application of membrane processes in various fields has now undergone accelerated developments, despite the presence of some hurdles impacting the process efficiency. Fouling is arguably the main hindrance for a wider implementation of polymeric membranes, particularly in pressure-driven membrane processes, causing higher costs of energy, operation, and maintenance. Radiation induced graft copolymerization (RIGC) is a powerful versatile technique for covalently imparting selected chemical functionalities to membranes’ surfaces, providing a potential solution to fouling problems. This article aims to systematically review the progress in modifications of polymeric membranes by RIGC of polar monomers onto membranes using various low- and high-energy radiation sources (UV, plasma, γ-rays, and electron beam) for fouling prevention. The feasibility of the modification method with respect to physico-chemical and antifouling properties of the membrane is discussed. Furthermore, the major challenges to the modified membranes in terms of sustainability are outlined and the future research directions are also highlighted. It is expected that this review would attract the attention of membrane developers, users, researchers, and scientists to appreciate the merits of using RIGC for modifying polymeric membranes to mitigate the fouling issue, increase membrane lifespan, and enhance the membrane system efficiency.

Abstract:
The discharge of massive amounts of oily wastewater has become one of the major concerns among the scientific community. Membrane filtration has been one of the most used methods of treating oily wastewater due to its stability, convenience handling, and durability. However, the continuous occurrence of membrane fouling aggravates the membrane’s performance efficiency. Membrane fouling can be defined as the accumulation of various materials in the pores or surface of the membrane that affect the permeate’s quantity and quality. Many aspects of fouling have been reviewed, but recent methods for fouling reduction in oily wastewater have not been explored and discussed sufficiently. This review highlights the mitigation strategies to reduce membrane fouling from oily wastewater. We first review the membrane technology principle for oily wastewater treatment, followed by a discussion on different fouling mechanisms of inorganic fouling, organic fouling, biological fouling, and colloidal fouling for better understanding and prevention of membrane fouling. Recent mitigation strategies to reduce fouling caused by oily wastewater treatment are also discussed.

Abstract:
AbstractA proof-of-concept study was designed to investigate using an Ultraviolet C (UVC) lamp mounted on a hull-crawling remotely operated vehicle (ROV) to prevent biofouling on a ship hull. A wheeled cart with a UVC lamp was built to expose two large test panels to UVC. The test panels were coated with an ablative copper antifouling and a silicone fouling release coating, and these were immersed in seawater at Port Canaveral, Florida. Three exposure frequencies (once a week, twice a week, and three times a week) and two dosages (8 and 16 s of UVC exposure) were tested. UVC was effective at preventing biofilm growth during the first 2 weeks of UVC treatment but was unable to prevent increased fouling growth as time progressed. It appears that an increase in UVC intensity and duration of exposure would be needed to prevent fouling growth especially during high-fouling seasons or that UVC exposure would need to be combined with another fouling prevention practice, such as mechanical wiping, to be more effective.

Abstract:
Abstract Fouling in papermaking causes major economic drawbacks due to downtime of process and paper quality defects. The surface fouling is a complex phenomenon in a paper making process, which is affected by several interconnected factors such as process environment changes from wet to dry with increasing temperature along with the variety of sticky materials present in paper raw materials. These impurities, such as waxes, coating binders, hot melts and pressure-sensitive adhesives have a tendency to attach to the surfaces of machinery during paper production and cause surface fouling. The focus of this thesis was on the mechanisms of sticking and surface fouling on a paper machine surfaces caused by problematic sticky organic materials. The sticking potential of six styrene–butadiene latices varying in carboxylation degree, crosslinking density and viscoelasticity and one polyacrylate pressure sensitive adhesive were studied using a cylindrical probe tack method under dry and aqueous conditions. Sticking potential was measured using low and high energy surfaces as an adherent. Also a new practical method for the on-site evaluation of nonstick properties of cylinder coating materials was developed. This method enables monitoring the condition of the coating during its life cycle and also provides the opportunity to compare the performance of different drying cylinder coating materials. The research performed clearly showed that low viscoelastic modulus of latex increases sticking tendency. The results also showed that presence of water can either increase or decrease adhesion depending on the moisture content ant the physic-chemical properties of sticky materials. A low surface energy coating strongly decreases sticking compared to a high energy surface and have a lower susceptibility to fouling in the dry environment. In aqueous conditions, the use of high-energy surfaces decreases adhesion of latices due to their strong interaction with water. Also, the results indicated that carboxylation decreases sticking potential of latex in both dry and aqueous environments
Tiivistelmä Paperikoneiden likaantuminen aiheuttaa suuria tuotannollisia menetyksiä johtuen tuotantoprosessin katkoksista ja paperin laadun ongelmista. Paperikoneen pintojen likaantuminen on monimutkainen prosessi, johon vaikuttavat monet toisistaan riippuvat tekijät ja siten likaantumisilmiötä on vaikea hallita. Paperin raaka-aineet voivat sisältää epäpuhtauksia, kuten vahoja, kuumasulate- ja tarraliimoja, jotka tarttuvat paperikoneen pintoihin aiheuttaen niiden likaantumista. Lisäksi paperin prosessiympäristö muuttuu märästä kuivaan valmistusprosessin edetessä ja lämpötilan kasvaa samanaikaisesti. Tässä väitöskirjassa on kuvattu paperikoneen pintojen likaantumisen mekanismeja ja erityisesti orgaanisten lika-aineiden tarttumista. Tutkimuksessa selvitettiin probe tack -menetelmää käyttäen kuuden erilaisen styreeni-butadieenilateksin ja polyakrylaattitarraliiman tarttuvuutta matalan ja korkean pintaenergian pinnoilla sekä kuivissa että märissä olosuhteissa. Työhön oli valittu latekseja, joiden karboksylointiaste, ristisilloitustiheys ja viskoelastiset ominaisuuden olivat erilaisia. Lisäksi väitöskirjatyössä kehitettiin paikan päällä suoritettava mittausmenetelmä paperikoneen kuivaussylinterien pinnoitteen puhtaana pysyvyyden määrittämiseksi. Tällä menetelmällä voidaan mitata pinnoitteiden kuntoa niiden elinkaaren aikana ja myös vertailla erilaisia pinnoitteita keskenään. Tutkimuksen tulokset osoittivat, että styreeni-butadieenilateksien matala kimmokerroin lisää niiden tarttumista paperikoneen pinnoille. Veden läsnäolo voi joko lisätä tai vähentää tarttumista riippuen veden määrästä ja lika-aineiden fysiokemiallisista ominaisuuksista. Myös paperikoneen pinnoitteen pintaenergia vaikuttaa tarttuvuuteen. Paperikoneen pinnoitteiden pieni pinta-energia vähentää tarttumista kuivissa olosuhteissa, kun taas korkean pintaenergian pinnoitteet vähentävät lateksien tarttuvuutta vesiolosuhteissa. Lisäksi lateksien karboksylointi vähentää niiden tarttumista sekä kuivissa että märissä olosuhteissa

Abstract:
Microorganisms attachment to the surfaces located in the marine water has become a significant problem. Historically, the antifouling properties of the coatings were achieved by using biocides, which had a negative consequence to the marine environment. Currently, alternative environmental friendly methods are required. This thesis aimed to investigate and produce the antifouling coatings that can be used as potential candidates in the marine industry. In this study, a range of novel polymer nanocomposite coatings was fabricated via the method of solvent and tested based on the strategy of microbial adhesion. The composition of the coatings mainly contains polidimethylsiloxane (PDMS) and different nanomaterials. The coatings applied on glass substrate were characterised using X-ray spectroscopy (XRD), scanning electron microscopy (SEM), contact angle measurements, inductively coupled plasma mass spectroscopy (ICP-MS) and atomic force microscopy (AFM). In biofouling assays, attachment of bacteria B. Subtilis and three marine microalgae (Skeletonema sp., Amphora sp., D. Salina) was investigated in laboratory scale. The obtained results suggested that small amount of nanoparticles in the polymer matrix can improve the antifouling settlement behaviour of the coatings. All microalgae attached more on PDMS/SiO2 and control surfaces (glass and PDMS) compared to the coatings containing multiwall carbon nanotubes (MWCNT) and sodium bismuth titanate (NBT). The influence of contact time, surface roughness and surface wettability was also studied. The microbial attachment varied significantly with respect to contact time and surface properties. There was no obvious evidence showing that the wetting properties and the roughness of the coatings have an effect on growth ... [cont.].

Abstract:
Marine biofouling is the accumulation of organisms onto surfaces immersed in sea water. Fouling of ships causes an increase in hydrodynamic drag which leads to performance issues such as increased fuel consumption and a reduced top operating speed. Fouling-release (FR) coatings are one way that paints have been used in combating biofouling by allowing for the easy removal of settled organisms. Traditional FR coatings are silicone elastomers which are soft, easily damaged, and require a tie coat for adhesion to marine primers. Siloxanepolyurethane FR coatings have shown promise as FR coatings, providing enhanced durability and toughness, better adhesion to marine primers, and comparable FR performance to commercial coatings. Preliminary studies were conducted to explore the use of PDMS macromers in the preparation of siloxane-polyurethane FR coatings. Attachment and removal of fouling organisms on the siloxane-polyurethane coatings based on PDMS macromers was comparable to commercial FR coatings. Extended water aging was also carried out to determine effects of extended water immersion on the fouling-release performance of the coatings. At up to four weeks of aging, the FR performance of the coatings was not affected. Static immersion marine field testing was performed to determine the fouling-release performance of siloxane-polyurethane coatings prepared with PDMS macromers. The performance was found to be comparable to commercial FR coatings for up to one year, including water jet removal of slimes, barnacle push-off removal, and soft sponging. The coatings showed good fouling-release performance until extremely heavy fouling was allowed to settle. Underwater hull cleaning was conducted for one siloxane-polyurethane composition identified as a top performer from static field testing. The coating was easily cleaned of fouling with rotating brushes for six months. The cleaning capability of the coating was reduced when large barnacles and other extremely heavy fouling was present. A commercial FR coating became heavily damaged with brush cleaning while the siloxane-polyurethane coating remained mostly undamaged. With more frequent cleaning, it is suspected that siloxanepolyurethane coatings would show cleaning capability for longer periods of time. Pigmentation of siloxane-polyurethane coatings based on difunctional PDMS and PDMS macromers was explored to investigate the effect on FR performance. Pigmentation with titanium dioxide caused a slight decrease in FR performance in some cases, but this was easily overcome by the addition of slightly more PDMS in the coating binder, thus illustrating the feasibility of siloxane-polyurethane coatings as effective, pigmented FR coatings. Finally, the exploration of unique PDMS polymer architectures has been explored for the development of additional, novel, fouling-release coatings. The incorporation of end-functional PDMS homopolymer molecular brushes and branched PDMS macromers into siloxane-polyurethane fouling-release coatings shows promise for the development of unique coatings where improved FR performance may be obtained.

Abstract:
The unwanted build up of fouling organisms on immersed structures has been a problem that has been addressed over the years in many different ways, from tar and pitch on the hulls of vessels to various toxin based ablative coatings and most recently, foul-release coatings that present a non stick surface to which organisms can not adhere strongly. These foul-release coatings have been relatively successful and further investigation into the formulation of siloxane based coatings is a environmentally acceptable and commercially viable concept. The significance of the hydrophilicity of a range of cured siloxane polymers upon the attachment of marine fouling species is presented. The polymers were synthesised from polymethylhydrosiloxane (PDHS) with the grafting of hydrophilic ethoxy based, linear chains of various lengths. Following cross linking, films of these materials were characterised by Nuclear magnetic resonance (NMR), Infrared (lR) spectroscopy, X-ray photoelectron spectroscopy (XPS), contact angle goniometry, topography, thermal analysis, sorption of water, force of adhesion and nano-indentation. The films were tested by bacterial growth and attachment studies, the growth and attachment of various algal propagules and also by static raft trials. Results suggest that there is a maximum hydrophilic content possible when investigating these coatings, due to the intake of water molecules, which causes swelling and subsequent degradation of the stability of the coating. The optimum hydrophilic content for achieving minimum adhesion of fouling organisms was unclear, however, trends in experimental data were identified. The bacterial attachment and growth studies conducted upon Fucus propagules indicated an increase in growth upon the PMHS polymers with the addition of3-{2-[2-(2-methoxy-ethoxy)-ethoxy]ethoxy}- propene groups, while the Sargassum propagules illustrated a reduction in growth during the same conditions. Ulva and Enteromorpha propagules showed no visible trends in growth upon the coatings tested. The surface energy and adhesion results illustrate that the PDMS with 3-{2-[2- (2-methoxy-ethoxy)-ethoxy]-ethoxy}-propene groups were the most adhesive of the coatings teste4 (14.9 oN in comparison to 3-9 oN) but possessed the lowest surface energy (22.46 mJ m2 ). In exposure trials over a 10 month period, the peroxide cured coatings out performed the other curing systems tested, however the colonisation of the range of polymers was inconclusive.

Abstract:
AbstractThe use of medical devices, such as urinary stents, catheters, artificial heart valves, prosthetic joints and other implants, collectively often referred to as “biomaterials” has increased dramatically over the past century, and has become a major part of modern medicine and our daily life. With the aging society, the higher demand on these devices to restore function and quality of life, combined with the ever improving technology within the medical field, the problem of biomaterial-associated infection (BAI) is expected to increase.The most common causative microorganisms in BAI are Staphylococcus aureus, a major pathogen in wound infections, and Staphylococcus epidermidis, the harmless skin commensal. Depending on the type of device and location of application, other pathogens such as coagulase-negative staphylococci, enterococci, streptococci, Propionibacterium acnes and yeast can also cause BAI.Prevention of BAI is a challenging problem, in particular due to the increased risk of resistance development associated with current antibiotic-based strategies. Here we showed the evidence of biofilms as a source for peri-implant tissue colonization, clearly showing the importance of preventive measures to be able to act both against implant and tissue colonization. Subsequently, we described different strategies to prevent BAI and other difficult-to-treat biofilm infections. We conclude that future research should focus on the development of combination devices with both anti-fouling or contact-killing capacities—to protect the implant—and controlled release of an antimicrobial agent to protect the surrounding tissue.

Abstract:
AbstractHuman body has evolved multiple strategies such as the development of a complex immune system and procurement of commensal microorganisms to deal with detrimental invasion by microbes. Despite this, biofilms pose an extremely difficult mechanism for humans to cope with infections caused by both pathogenic and opportunistically pathogenic microorganisms. Biofilms on urinary stents can lead to patient-discomfort, urinary tract infection and bacteriuria, antimicrobial resistance, stent fouling (encrustation) and obstruction. Currently, biofilm prevention and treatment in ureteral stents are carried out using a ‘static’ coating of the stent with heparin or a pH control-buffer. They increase patency but still becomes colonised by bacteria leading to biofilms. In this chapter we outline a patent-pending first-principle design strategy for a stent-coating stents that has the potential of increasing the patency by manifold and, at will. This strategy involves delaying biofouling with a ‘dynamically degradable surface’ and will be described in this chapter.

Abstract:
Environmental protection concerns continue to drive the coatings industry to seek innovative and efficient solutions to problems that arise from biofouling on ship-hulls. Fouling Release coatings have historically been biocide-free due to a very limited effect of the biocides. This paper describes the introduction of biocides with hydrogel into Fouling Release technology. By fusing hydrogel-based Fouling Release technology with less than 5%w of the biocides used in conventional antifouling coatings, an antifouling performance exceeding that of conventional antifouling coatings, as well as state of the art Fouling Release coatings has been achieved. It is shown that the biocide release rate from the new technology does not depend on speed for velocities ranging between 0.2 and 20 knots (0.37 –37 km/h). However, at increasing temperatures, the biocide release rate increases, thereby matching the increase in fouling pressure. Taking together, the very long-term antifouling performance of the biocide-activated hydrogel, the fuel-efficiency of the binder system, the efficient utilization of biocides even at high speeds and low temperature, it is concluded the technology described here is both the most efficient and environmentally friendly Fouling Control coating available.

Abstract:
Abstract Mineral scale formation and deposition in down-hole completion equipment such as subsurface safety valves can cause dramatic and unacceptable safety risks and associated production losses and operational costs. Current scale removal strategies involve both mechanical and chemical technologies, each of them having their own advantages depending on the type of mineral scale and its location. However, these techniques are often costly and of limited efficiency. The current study assesses the ability of a range of chemically and morphologically modified coatings to prevent/reduce mineral scale surface fouling. Building-up on previous work done under static conditions, this paper presents results from scaling tests under laminar and turbulent dynamic conditions using a rotating cylinder electrode under in a complex (mixed) scaling environment (supersaturated w.r.t. calcium carbonate, barium sulfate, strontium sulfate, barium carbonate and strontium carbonate). The study shows that if properly selected, surface treatments represent a promising approach to reduce scale deposition on downhole equipment surfaces that are critical to maintain equipment functionality and thereby well safety barrier integrity. By analyzing the scaling behaviors observed within the set of surfaces tested, suggestions of the controlling factors in anti-fouling on these systems are presented and discussed.

Abstract:
Abstract A concurrent approach to hierarchical selection of design concepts for maintenance management is introduced. The interactions amongst selection problems in maintenance are taken into account concurrently by formulating an entire hierarchy as a single coupled Decision Support Problem (DSP). Using this method it is possible to model interactions among different concepts rather than creating a model in which these decisions are made sequentially, hence this approach can form a basis for concurrent engineering. We illustrate our approach by formulating and solving a gas turbine axial compressor fouling maintenance problem as a coupled selection-selection DSP. The filter for fouling prevention and the washing media for fouling treatment are selected simultaneously while interactions between the two selections are considered. Our focus in this paper is on explaining our approach rather than the results per se.

Abstract:
Generating companies lose hundreds of millions of dollars annually to problems related to condenser and heat exchanger fouling, corrosion and tube leaks. In fact, the Condenser Tube Failure Control Program of Electric Power Research Institute (EPRI, Matthews, J.) disclosed that condenser tube failures contributed to almost 25,000 outages nationwide during a recent four year period and continue to be one of the most pressing issues related to plant output and availability. To adequately prevent condenser tube failures, effective condenser tube cleaning and nondestructive testing must be performed. Effective tube cleaning should ideally remove all deposits, leaving only the cleanest metal surface. Once tubes are free of fouling deposits, multi-frequency eddy current testing should be used to establish the overall integrity of condenser tubes. Plugging is recommended for the tubes with poor integrity that put condenser reliability at risk. If tube failures do occur, advances in tracer gas leak detection, specifically those using sulfur hexafluoride and helium, can be used to quickly locate sources of circulating water tube leakage and return the unit to reliable operation. This paper will examine implications of condenser tube fouling and failure, and the available nondestructive technologies for their prevention and correction.
