Considerations and Case Studies for Ultrafiltration in Small‐Scale Applications

摘要

Advancements in system design, equipment options, membrane materials, and module designs haverncombined to make ultrafiltration systems an attractive equipment option for small‐scale utilities. Thisrnpaper describes a variety of design aspects considered by system engineers and equipment manufacturersrnwhen designing and building a membrane filtration plant. Recent trends in membrane system design,rnsuch as the open‐platform system concept, are discussed. In addition, the results of a pilot study arernshown which demonstrate the effectiveness of one of the high‐quality UF membranes available on thernmarket. Finally, case studies of challenging small‐scale systems in Utah and Oregon are discussed.
