To comply with Ontario's new water regulations and meet future regulations and water demand, the Town of Tecumseh near Windsor, Ontario, Canada, decided to upgrade their 7.2 USMGD (27.3 ML/D) Tecumseh Water Treatment Plant (WTP) by implementing membrane filtration. This paper discusses design issues in the conversion of a conventional filtration plant to a membrane filtration plant that include: pre-treatment; system flow requirements/staging; plant retrofit; design temperature; cleaning regime; recovery rate; raw water maximum and instantaneous flows; double pumping and power requirements; chemical requirements; and, residue management. Specific examples related to the Tecumseh WTP Upgrades project are presented. Includes 3 references, tables, figures.
