Pumping Sludge and Slurry
Wiley, Mar 13, 1998 - Science - 80 pages
The handling of solid/liquid mixtures is a process widely used throughout industry. It is successfully employed in a wide range of situations, from mineral extraction, processing of food and pharmacuetical products to general industrial processes. This text includes a selection of papers which aims to make engineers and managers aware of the capabilities of the current methods which are now available. Topics covered include: sludge and slurry pumping; rheology of non-Newtonian pipe flows; energy-efficient use of submersible centrifugal pumps; pumping of abrasive hydrocarbons; and positive displacement pumps. The volume should be of interest to those involved in the design, specification, selection, installation, use and maintenance of pumping equipment for the transportation of non-Newtonian liquids and liquids containing substantial quantities of the suspended solids.
