Wastewater Treatment and Reuse

As a result of a request by a large industrial user for a water supply that meets quality standards considerably more stringent than those applied to public drinking water, a 6‐year program involving numerous studies, tests, and plant changes and additions was undertaken by the Old Dominion Water Corporation in Hopewell, Virginia. The high‐quality water requested was to be used in producing a premium grade of nitrocellulose. This article discusses the improvement in water quality from 1955 to 1960 that was brought about mainly by introducing free residual chlorination, pH correction before filtration, the use of activated silica, the development of laboratory control procedures, and the provision of laboratory and plant recording instruments.
