Book Description
In this one-of-a-kind book, Dr. Rovenia M. Brock—known as Dr. Ro™ to fans of Black Entertainment Television’s Heart & Soul—reveals practical, satisfying ways for African American women to eat healthy, get fit, and overcome weight problems and the health risks that accompany them. From the “Big Ten” myths about miracle weight-loss diets to how eating the right foods can help you live longer and why soul food (if prepared properly) really can be good for you, Dr. Ro shows how many serious illnesses can be largely prevented—and even reversed. And you don’t need Oprah’s salary to do it. Using her own inspiring story and those of many other women as well, Dr. Ro discusses the health, fitness, and even cultural issues that are unique to black women, and outlines a diet and nutrition program to fit every lifestyle.

Book Description
The most comprehensive and up-to-date coverage of reverse osmosis in industrial applications. Reverse osmosis is rapidly growing as a water treatment technology used for many applications, such as boiler feed water and recovering wastwater for reuse. This "green" technology is becoming more and more widely used in many settings, especially in industry. Even as the technology becomes more widespread, the understanding of the technology is lagging behind. Reverse Osmosis provides an essential reference for any process or chemical engineer working with this emergent technology. This outstanding reference: Provides a comprehensive and thorough coverage of reverse osmosis technology Discusses fundamental processes and equipment for operating and troubleshooting a reverse osmosis system, such as reverse osmosis principles, membrane technology, and flow patterns Covers more advanced engieering topics for specific industrial applications, such as system design Features clear, consise language written in easy-to-understand language, providing engineers immediate ability to implement a reverse osmosis program

Book Description
Seawater reverse osmosis (SWRO) is the dominant desalination process worldwide for obtaining fresh water from the sea. The subject matter and scope of this book is the conceptual and advanced planning, design and engineering of plants of this desalination process together with the associated facilities for seawater pretreatment, post-treatment of the product water, wastewater treatment, seawater extraction and plant discharge. The book is intended to be used by technicians, engineers, economists and ecologists in the planning, design and operation of SWRO plants, as an educational and training tool, as well as an aid in environmental licensing of membrane desalination plants, and by interested laypersons for information about this process. The two volumes are also available as a set.

Book Description
This new edition of the bestselling Reverse Osmosis is the most comprehensive and up-to-date coverage of the process of reverse osmosis in industrial applications, a technology that is becoming increasingly more important as more and more companies choose to "go green." This book covers all of the processes and equipment necessary to design, operate, and troubleshoot reverse osmosis systems, from the fundamental principles of reverse osmosis technology and membranes to the much more advanced engineering principles necessary for designing a reverse osmosis system. The second edition is an enhanced version of the original best seller. Each chapter has been reviewed and updated. Revised features include more detail on various pretreatment techniques such as greensand and pyrolusite pretreatment media. The design projection chapter has been edited to include up-to-date information on current projection programs. A new section on microbial fouling control featuring chlorine and alternative techniques is included to address the needs of most RO systems. Also, a discussion on forward osmosis is added as an alternative and/or companion technology to reverse osmosis for water treatment. The second edition includes all updated, basic, in-depth information for design, operation, and optimization of reverse osmosis systems. Earlier chapters cover the basic principles, the history of reverse osmosis, basic terms and definitions, and essential equipment. The book then goes into pretreatment processes and system design, then, finally, operations and troubleshooting. The author includes a section on the impact of other membrane technologies and even includes a "Frequently Asked Questions" chapter.

Book Description
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.

Book Description
Reverse Osmosis starts with an overview of the historic development of the RO membrane, the RO process, and its effect on other membrane separation processes. Other chapters cover the development of nanocomposites of TFC membranes and modern membrane characterization techniques, such as TEM, AFM and PALS, the RO membrane transport model, and RO membrane fouling. The book also describes, in detail, experimental methods for setting up RO experiments, RO membrane modules, RO membrane systems, and desalination and water treatment by RO. Applications in food, pharmaceutical, chemical, biochemical, petroleum and petrochemical industries are also summarized. Other sections cover the development of RO membranes with high thermal and chemical stability, attempts to develop polymeric or inorganic membranes, and hybrid processes where RO is combined with forward osmosis (FO) or membrane distillation (MD). - Written by renowned experts in the field who have complementary expertise - Provides an in-depth discussion of reverse osmosis transport based on nano-level membrane structure - Comprehensively reviews recent progresses in novel reverse osmosis membrane development
