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

Book Description :

The reverse osmosis process is discussed with particular reference to systems involving aqueous solutions and Loeb-Sourirajan-type porous cellulose acetate membranes. Mechanisms of the process and porous cellulose acetate membrane technology are briefly reviewed. Based on a general capillary diffusion model for the transport of solvent and solute through the membrane, transport equations applicable for the entire range of solute separation are presented. The results of the analysis and correlations of experimental reverse osmosis data are illustrated. On the basis of the above equations and correlations, methods of membrane specification, expressing membrane selectivity, and predicting membrane performance are outlined. Reverse osmosis is then treated as a unit operation in chemical engineering. A set of general equations for reverse osmosis process design is then derived for reverse osmosis systems specified in terms of membrane specifications and operating conditions. (Author).

Book Description :

Much of man’s technological innovations today have been borrowed mostly from nature. One of them is a very important process called “reverse osmosis”. It is the opposite of the natural process called osmosis. What, then, is reverse osmosis and what does it do? As man moves towards progress, water and the other natural resources of the world have become polluted and unsafe for use. Reverse osmosis is one of today’s important methods for processing water to make it clean and safe for use.

Book Description :

For the Nonengineering Professional Perfect for anyone without a background in science or engineering who wants to take a closer look at how water is processed and treated, Reverse Osmosis: A Guide for the Nonengineering Professional relates reverse osmosis in its most basic form and addresses growing concerns about the quality of tap water. What is reverse osmosis? Not to be confused with filtration—which involves straining or size exclusion—reverse osmosis involves a diffusive mechanism and separation process that is dependent on solute concentration, pressure, and the water flux rate. This book describes all of the basic processes involved in reverse osmosis operations. Presented in a conversational style—using jargon-free language—it discusses in detail the drinking water purification, wastewater reuse, desalination processes, and other freshwater applications used to ensure the safe consumption of water. The book also places special emphasis on pharmaceuticals and personal care product (PPCP) contaminants, which are not typically removed from wastewater by conventional treatment processes, however, they can be removed by processes using sophisticated membrane filtration. The author provides a basic understanding of membrane technology, and explains the membrane treatment process. He details how the processes fit together within a drinking water or wastewater treatment system and presents concepts that make up water and wastewater treatment processes as a whole. He also highlights advances in reverse osmosis technology and discusses relevant applications. Presents a comprehensive coverage of reverse osmosis Discusses fundamental processes and equipment used in reverse osmosis Provides technical terminology in simplified form Reverse Osmosis: A Guide for the Nonengineering Professional explains how reverse osmosis is used in drinking water purification and provides readers with step-by-step instruction on the pretreatment, treatment, and post-treatment technology used in the purification of drinking water.

Book Description :

Pollution of water sources with emerging contaminants (micropollutants) is a fact known worldwide. Although the risks of micropollutants in sources of water are partly recognized, interpretation of consequences are controversial; thus, the future effects of altered water with micropollutants remains uncertain and may constitute a point of concern for human beings when potable water consumption is involved. Therefore, many drinking water utilities target as an important goal high-quality drinking water production to lessen quality considerations that may arise from the consumers. In this thesis, by means of the use of multivariate data analysis techniques, removal quantification is effectively determined and more understanding of the separation of micropollutants by membranes is achieved.

Book Description :

Characterizing bulk organic matter in seawater and bay water by various analytical techniques and linking these measurements with fouling in membrane systems. Furthermore, it aimed for the development of the Modified Fouling Index - ultrafiltration (MFI-UF) at constant flux filtration as an accurate test to measure the particulate fouling potential of a feed water and predict the rate of fouling in reverse osmosis systems. A new semi-portable set-up has been successfully developed to perform MFI-UF tests at constant flux filtration. A significant effect of the filtration flux on the fouling potential was found. Consequences of this effect for reverse osmosis systems are that the fouling potential at low flux drops dramatically; for ultrafiltration systems it implicates that the rate of fouling increases at high fluxes. The observed effect of flux on the fouling potential has significant implications for fouling potential measurements. Deposition factors in RO systems varied between 0 and 1, depending on location and MFI pore size, which indicates differences in properties of the particles present. Fouling potential results in RO fouling rates of 0.2-1 bar/month depending on the pore size of the membranes used for MFI measurements. The fouling potential of the analysed raw waters is substantially reduced by conventional pre-treatment systems and ultrafiltration: for conventional pre-treatment 37 % - 74 % and ultrafiltration 60 % - 95 %, depending on the location and the MFI pore size.
