Processes for advanced treatment of water

A case-oriented approach is used to illustrate developments and application s of biological and physicochemical technologies, either alone or in sequen ced arrays, for advanced treatment to facilitate reuse of water in a range of environmental scenarios. Examples cited include chemical oxidation proce sses for removal of color and oxygen demand from textile mill effluents, se quential anaerobic/aerobic biological treatment of recalcitrant and inhibit ory organic compounds in ammunition plant wastewaters, separation and recov ery of organic solvents from mixed industrial waste streams, remediation of contaminated subsurface waters, membrane treatment of effluents from secon dary biological wastewater treatment plants, and integrated bio-membrane tr eatment of industrial and municipal wastewaters. The paper provides an over view of methods and applications for source waters of various qualities. It concludes with a generalized guide to technology selection based upon spec ific water characteristics. (C) 1999 IAWQ Published by Elsevier Science Ltd . All rights reserved.
