Design Completion and Update on the Largest Ultrafiltration Retrofit in Florida for Lake Manatee WTP

This abstract will give an update on design and procurement of Florida’s largest low-pressure membrane facility: i.e., 54-mgd ultrafiltration (UF) retrofit at Lake Manatee Water Treatment Plant in Manatee County. This project also reflects the largest planned UF retrofit in the US. The project includes refinements of existing pretreatment system, addition of pre-screens, replacement of media filters with 12 immersed UF trains, and addition of ancillary systems including CIP system, neutralization system, backwash system, air system, and chemical feed and storage systems. This abstract provides the water industry with important information on project status, a design and procurement approach, and lessons learned.
