Focusing on the application of membranes in an engineering context, this hands-on computational guide makes previously challenging problems routine. It formulates problems as systems of equations solved with MATLAB, encouraging active learning through worked examples and end-of-chapter problems. The detailed treatments of dead-end filtration include novel approaches to constant rate filtration and filtration with a centrifugal pump. The discussion of crossflow microfiltration includes the use of kinetic and force balance models. Comprehensive coverage of ultrafiltration and diafiltration processes employs both limiting flux and osmotic pressure models. The effect of fluid viscosity on the mass transfer coefficient is explored in detail, the effects of incomplete rejection on the design and analysis of ultrafiltration and diafiltration are analysed, and quantitative treatments of reverse osmosis and nanofiltration process analysis and design are explored. Includes a chapter dedicated to the modelling of membrane fouling.

The objective of this research was to investigate the clogging process in riverbank filtration (RBF) systems and identify factors significant to yield. Specific objectives included the following:

  • Evaluate commonly available stream and aquifer characteristics from RBF systems with regards to system yield
  • Collect data from the RBF system in Louisville and apply the information to clogging theory
  • Provide recommendations regarding the design of future RBF systems with regards to riverbed clogging
  • Data from the participating sites were compiled to allow easy comparison to future RBF sites.
High-capacity RBF systems have been constructed in a wide range of hydrogeologic settings, and data from these sites provide insight to capacity-limiting factors in RBF systems. Field data for temperature, head, and riverbed flux rates into the riverbed were collected at Louisville, allowing estimates of riverbed hydraulic conductivity to be calculated as a function of distance from the well. These data indicated variations in riverbed hydraulic conductivity resulting from riverbed clogging and the development of unsaturated conditions. The impact of temperature on specific capacity was evaluated at four sites where adequate operating data were available. Wide variations in water viscosity associated with temperature resulted in the doubling of specific capacity from winter to summer, indicating that the rated capacity of RBF systems should be considered as a range between coldest and warmest water conditions. Information from this project was summarized into a set of recommendations for utilities considering the design of an RBF system for future water supply.

A Guide to Filtration with String Wound Cartridges: Influence of Winding Parameters on Filtration Behaviour of String Wound Filter Cartridges explains the science behind winding phenomena with reference to the use of string wound cartridges in various environments, and is helpful in educating aspiring researchers and technicians on these new technologies that seek to quell the ongoing scarcity of water through the use of new and emerging filtration techniques.

The book provides detailed information about cartridge winding parameters, the number of layers put on the cartridge, their necessary availability, and the retention capacity and pressure drop. In addition, the book provides guidelines regarding the selection of winding variables so that new cartridges that cater to the specific porosity of different sized particles can be developed.

  • Presents data and conclusions that are based on actual experimental work
  • Provides explanations on why winding parameters influence the performance of wound cartridges
  • Describes problems encountered during cartridge formation and during its use in filter testing
