Download or read book Fouling Organisms of the Indian Ocean written by Rachakonda Nagabhushanam and published by CRC Press. This book was released on 2020-08-13 with total page 551 pages. Available in PDF, EPUB and Kindle. Book excerpt: Marine fouling organisms attach permanently to ship hulls and underwater parts of offshore structures. All maritime nations spend millions, even billions of dollars to get rid of them. Believing that a pooling of knowledge of all aspects of the basic biology of fouling organisms and a re-examination of control technology methods are steps needed for the solution of this problem, the aim of the book is to highlight recent advances in fouling control technology and, at the same time, provide basic information on the biology of fouling organisms found in the Indian Ocean. The book begins by presenting an overview of research done in India on the marine fouling organisms and wood-borers of the Indian Ocean. It them moves through chapters dealing with the seccession of fouling communities, chemical cues in larval settlement, epibiosis, methods of fouling prevention, functional morphology, and distribution of foulers in Indian waters.

This book was released on 2017-12-01 with total page 208 pages. Available in PDF, EPUB and Kindle. Book excerpt: Seawater desalination is a rapidly growing coastal industry that is increasingly threatened by algal blooms. Depending on the severity of algal blooms, desalination systems may be forced to shut down because of clogging and/or poor feed water quality. To maintain stable operation and provide good feed water quality to seawater reverse osmosis (SWRO) systems, ultrafiltration (UF) pre-treatment is proposed. This research focused on assessing the ability of UF and other pre-treatment technologies to reduce biofouling in SWRO systems. An improved method to measure bacterial regrowth potential (BRP) was developed and applied at laboratory, pilot and full scale to assess the ability of conventional UF (150 kDa) and tight UF (10 kDa) alone and in combination with a phosphate adsorbent to reduce regrowth potential and delay the onset of biofouling in SWRO. The improved bacterial regrowth potential method employs a natural consortium of marine bacteria as inoculum and flow cytometry. The limit of detection of the BRP method was lowered to 43,000 ± 12,000 cells/mL, which is equivalent to 9.3 ± 2.6 μg-Cglucose/L. The reduction in bacterial regrowth potential after tight UF (10 kDa) was 3 to 4 times higher than with conventional UF (150 kDa). It was further reduced after the application of a phosphate adsorbent, independent of pore size of the UF membrane. Pilot studies demonstrated that the application of tight UF (10 kDa) coupled with a phosphate adsorbent consistently lowered the bacterial regrowth potential and no feed channel pressure drop increase was observed in membrane fouling simulators (MFS) over a period of 21 days. The study also showed that non-backwashable fouling of UF membranes varied strongly with the type of algal species and the algal organic matter (AOM) they release. The presence of polysaccharide (stretching -OH) and sugar ester groups (stretching S=O) was the main cause of non-backwashable fouling. In conclusion, this study showed that an improved BRP method is suitable for the assessment of SWRO pre-treatment systems and it can be a useful tool to develop potential strategies to mitigate biofouling and improve the sustainability of SWRO systems.

Available in PDF, EPUB and Kindle. Book excerpt: Corrosion Management of Seawater Cooling Systems, Volume 71 provides an overview on main seawater heat exchanger systems, different forms of corrosion, biocide treatments, corrosion, scale inhibitors, materials used, coatings and cathodic protection, maintenance, and monitoring and control. The book will be a valuable reference resource for academics, technicians and engineers who are interested in the corrosion management of seawater cooling systems. The evolution of practices in terms of sustainability, materials choice, treatment selection and changes to regulations have demonstrated the need to establish this new guide on recommended best practices that support corrosion management and the development of seawater heat exchangers. Seawater is considered an attractive resource for utilities in many industries such as power plants, refineries and chemical plants. Seawater cooling systems are used in heat exchangers, in once-through cooling water systems, and for recirculating cooling water systems. The metallurgy and materials used in these facilities need to be compatible with seawater and allow good corrosion control. As seawater composition and suspended solids can cause corrosion, scaling, fouling, microbiological growth and macrofouling problems, this book is a necessary addition to the conversation. - Covers key technological developments in corrosion management of seawater cooling systems - Includes coverage of seawater heat exchangers - Provides information on many different forms of corrosion - Presents tactics for the selection of materials, corrosion protections (inhibitors, coatings, cathodic protection) - Discusses maintenance, control, monitoring and inspection

This book was released on 2020-01-21 with total page 146 pages. Available in PDF, EPUB and Kindle. Book excerpt: Seawater desalination is increasingly being used as a means to augment freshwater supplies in regions with high water stress, and reverse osmosis is increasingly the technology of choice because of the low energy consumption. However, seawater reverse osmosis (SWRO) systems suffer from various types of fouling, which can increase energy consumption and the use of chemicals during SWRO operation. In practice, pre-treatment systems are put in place to reduce the particulate and biological fouling potential of SWRO feed water. However, simple, reliable and accurate methods to assess the extent to which biological fouling potential is reduced during pre-treatment are not available for seawater. This research developed a new method to measure bacterial growth potential (BGP) using the native bacterial consortium in seawater. New reagents to extract and detect ATP in microbial cells were specifically developed for seawater. The new lysis and detection reagents overcame the salt interference in seawater and allow low detection of total ATP, free ATP and microbial ATP in seawater. Incorporating a filtration step further increased the sensitivity of the method six fold, enabling ATP detection of ultra-low levels of microbial ATP in seawater. The newly developed ATP-based BGP method was applied to monitor and assess the pre-treatment of five full-scale seawater desalination plants around the world. A good correlation was observed between BGP measured in SWRO feed water and the pressure drop increase in the SWRO systems, suggesting the applicability of using the ATP-based BGP method as a biofouling indicator in SWRO. Furthermore, a safe level of BGP ( In the future, on-line monitoring of BGP in SWRO feed water may further reduce the consumption of chemicals and energy and improve the overall sustainability of seawater desalination by reverse osmosis.
