Membranes in Bioprocessing: Theory and Applications / Edition 1

by J.A. Howell, V. Sanchez, R.W. Field

Overview

1. A. HOWELL School ofChemical Engineering, University ofBath, Claverton Down, Bath, UK, BA2 7AY 1.1 WHAT IS A MEMBRANE PROCESS? Every day over 20 million litres of brackish water are pumped out of the ground near Jeddah in Saudi Arabia and passed through thin sheets of cellulose acetate known as reverse osmosis membranes before being used as part of the city's water supply. In St Maurice les Chateauneuf, France three million litres a day of ground water are ultrafiltered to supply the city and on test sites in Australia settled sewage is being disinfected by being passed through microfiltration membranes. Many of the foods we eat and beverages we drink have used membranes during their processing. Orange juice can be concentrated by membranes to make a concentrate which retains more of the flavour than does evaporation. Milk can be concentrated slightly by means of a membrane before making a cheese in a process which produces no whey. Gases rising from the ground in a waste tip can be piped away and the carbon dioxide separated from the methane by a membrane process allowing the methane then to be used as a fuel, simultaneously saving energy and reducing the greenhouse effect since methane is more effective as a greenhouse gas than carbon dioxide.

Editorial Reviews

For practitioners and advanced students in chemical engineering, biochemical engineering, and biotechnology, this volume covers the theory and use of the membrane processes that are of greatest value in bioprocessing. It deals with those processes most often used for processing liquids in biotechnology, with a focus on ultrafiltration, microfiltration, and pervaporation. The applications range from preparation of pure water, through harvesting of cells and concentration of products, to recovery of products such as dry ethanol. Note: although the volume is still identified as part of an Elsevier series, it is presently published by Chapman & Hall. Annotation c. Book News, Inc., Portland, OR (booknews.com)
