Ultafiltration (UF) technology is widely applied for surface water treatment due to the ability to consistently and reliably acheive high log removal of pathogenic organisms and low permeate turbidity. These systems are commonly used for drinking water applications, as well as pretreatment to nanofiltration and reverse osmosis systems. Two case studies are presented: the Greendale Water Company 200 GPM ultrafiltration plant, and the Maple Ridge Girls Camp 26 GPM ultrafiltration plant. The plants are compared and contrasted to show differences in design, installation, and operation. Additionally, the 2014 pilot study at the Greendale WTP is compared against the first six months of data from the full-scale plant, which started February, 2016, to identify similarities and differences found between the pilot and the full-scale installation.
