The objectives of this pilot study at the Hugh A. Wyckoff Water Treatment Plant, owned and operated by the Cobb County-Marietta Water Authority, were the following:
to obtain major design and operating criteria for a potential full-scale post-filter nanofiltration (NF)
facility; to
determine the fouling and scaling potential of the feed water; to
provide water samples for characterization of permeate and concentrate water quality; and,
to determine the corrosion potential and disinfection byproduct (DBP) formation potential of the
blended finished water. This paper describes the operational and water quality results from the pilot-scale evaluation of
post-filter NF membrane treatment. Additionally, one of the most significant issues for evaluating
the use of NF in north Georgia is the ability to identify a permittable and economical means of
concentrate disposal. A separate study was conducted to determine the water quality and
treatability testing performed on the concentrate and the potential disposal options (Isabel, 2007). Includes 4 references, tables, figures.
