ABSTRACT
The development of the ' Fyne' Process, from an operator's perspective, for the removal of humic colour from water is described. The use of cellulose triacetate nanofiltration membranes in both tubular and spiral wound configurations has been a major advancement in the treatment of highly variable coloured upland water sources in Scotland. Membrane technology has enabled full compliance with all drinking water legislation even at the remote island sites. Operational and cost comparisons of nanofiltration with conventional treatment technologies for colour removal are discussed.
