Available in PDF, EPUB and Kindle. Book excerpt: The transport-depletion process was investigated for demineralizing clarified or filtered municipal secondary effluent. Regenerated-cellulose membranes were not effective. The major problems encountered in demineralization of wastewaters by conventional electrodialysis, fouling and scaling, were, however, largely overcome by the use of a special anion-selective membrane and periodic flushing of the stack with sodium chloride solution. Membrane fouling was largely overcome by flushing the stack with a sodium chloride solution. Cost estimates are given.
