In 2015 the Clifton Water District completed a project to convert the its 34 year old, shallow bed media filters at its drinking water treatment plant to a more robust and reliable membrane filtration system. The conversion took place without interrupting water service to its customers over the 10 month period between ground breaking and the membrane system was put into service. In order to deliver the project without interruption to the water treatment plant, the design builder needed to keep the existing filter system operational during construction, build a membrane filtration system pipe gallery that shared space with the media filter gallery, and make a conversion from a pretreatment that relied on the use of cationic polymers to a more membrane compatible strategy that excluded those polymers. The presentation will provide operators with information on the key differences in piping system betweeen membrane and media filters. The presentation will also discuss the conversion of the pretreatment from a chemistry focused on gnerating a settle water quality for media filter to a chemistry focused on relaible membrane filtration system operation.
