Book Description
Water quality is a critical issue for the water industry today, and membrane filtration a highly effective treatment used to provide clean water for the global population. Experimental processes are being developed for assessing fouling, scaling, performance and modelling of membrane systems, and research is needed to further improve the sustainability and feasibility of these technologies, and to mitigate the challenges of water scarcity for billions of people, particularly in developing countries. This book aims to address this vital issue by bringing together experts in the field to share their learning, including: • Membrane processes: microfiltration (MF), ultrafiltration (UF), reverse osmosis (RO), forward osmosis (FO) and membrane distillation (MD) • Particulate fouling: silt density index (SDI), modified fouling index (MFI-0.45 and MFI-UF) • Inorganic fouling and scaling: assessment, characterization tools and mitigation • Organic fouling: size exclusion chromatography (LC-OCD), fluorescence spectroscopy (FEEM) and transparent exopolymer particles (TEP) • Biological fouling: genomic tools, bacterial growth potential (BGP) of seawater and low-nutrient water and optical coherence tomography (OCT) • General applications: membrane autopsy and computational fluid dynamics (CFD) modelling This book will be an important resource for undergraduate and graduate engineering students and researchers, academics, plant operators, consultants, professionals and practitioners in the water sector.

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
This book analyses the sustainability of membrane operations applied on an industrial scale, as well as that of those under investigation on lab/pilot scales, covering also the preparation of both polymeric and inorganic membranes. It presents reverse osmosis in desalination, membrane bioreactors for municipal wastewater treatment and pressure-driven industrial wastewater treatment in agrofood and textile fields as examples of industrial membrane operations. Regarding the membrane processes still on a lab/pilot scale, the analysis includes membrane operations for the recovery of valuable products from wastewater streams, for the removal of toxic compounds from water/wastewater, and for zero liquid discharge approaches in desalination. The book offers a useful guide for scientists and engineers working in various fields, including membrane technology, separation, desalination, and wastewater treatment. Alberto Figoli and Alessandra Criscuoli are both Senior Researchers at the Institute on Membrane Technology (ITM-CNR), Italy.

Book Description
Membrane technology with effective removal of microbial contaminants has been applied widely in drinking water treatment (DWT), but its sustainable and efficient application in rural areas still needs practical research. Backflushing and chemical cleaning are well investigated for membrane-based systems. However, these methods are not always followed properly and in full, especially in cases of applications for remote areas in developing countries. Important key challenges in real world applications are how the system would actually sustain with unskilled personnel, with no electric power for backflushing or with no chemical cleaning on the long run. These challenges were addressed within the framework of this dissertation. A dead-end Ultrafiltration (UF) with flat-sheet membranes was configured to a stationary DWT system working with low pressure and simplest maintenance, in combination with a suitable chlorination solution without energy demand. In the literature review of this dissertation, an overview of many up-to-date membrane based systems in different categories of use is given in detail, covering different aspects of technology, service efficiency and economics. Hydraulic performance of membrane-based systems is normally studied in lab-scale in limited periods from hours to days. Thus, highlight of this research is the investigation of a full-scale demonstration plant based on UF flat-sheet membrane with pore size of 40 nm, conducted in the Hydraulic Workshop at the University of Kassel, operated continuously day and night for long-term tests. The long-term examination focused on many aspects, from hydraulic performance including flux, permeability, transmembrane pressure, efficiency of the simple membrane cleaning methods, to biological quality of treated water and also efficiency of chlorination by using a mechanical chlorine dosing device. During long-term examination, the phenomenon of gas generation from the water in the plant was recognized. The influence of this phenomenon on the permeate flow rate was evaluated and solution for this problem by the gas trapping device was investigated in this research. The experimental results from long-term examination of the Pilot Plant at the University of Kassel served for the materialization of the system into life. Two DWT plants were implemented in a rural village in southern Vietnam. It could be proved that the product of this research is realistically an economic relief of the long lasted insufficient supply to the crucial demand for safe water in the rural communities of developing countries.
