Ft. Pierce Utility Authority (FPUA) Softener Rehabilitation

Globaltech, Inc.
St. Lucie County, Florida

Project Description

The FPUA requested the lime softener clarifier be rehabilitated at their Water Treatment Plant. The scope of the project included replacement of the launders, removal and replacement of the corroded upper section of the tank, and the addition of hatchways for improved maintenance and service. The existing circular steel tank was modeled by Finite Element Analysis for the stress increase due to the proposed penetrations. A four-foot by four-foot hatchway was designed and the tank, in the region of the penetration, was reinforced with additional plating to compensate for the concentrated stresses. In addition to the structural analysis and construction documents, construction phase services were also provided.
