Client: Port Saint Lucie, Florida

The City of Port Saint Lucie contracted with WPC Industrial Contractors to expand the existing James E. Anderson brackish water reverse osmosis (BWRO) treatment plant to the total build-out capacity of 20 MGD. The expansion added seven 2.0 MGD skids to the existing 6 MGD capacity that has been operational since 2004.

The seven 2.0 MGD BWRO trains will use Hydranautics ESPA2+ low pressure membrane elements. The project began with two skids completed in December 2006, followed by two additional skids in May 2007, and a final build-out in October 2007.

The structural components of the James E. Anderson trains are being manufactured from Extren fiberglass shapes, supporting Bekaert Progressive Composite PRO-8-300-SP pressure vessels and Pump Engineering LPT-1000 energy recovery devices. The pressure vessels are interconnected using conventional stainless steel manifolds with all feed, concentrate and most permeate piping constructed of 316 stainless steel.

Aerex’s® scope included provision and installation of the membrane process trains, status panels, sample panels and all of the stainless steel and PVC piping located inside the process building. In addition, Aerex® fabricated all of the 316 stainless steel piping throughout the facility for WPC Industrial Contractors.

Aerex® supplies all engineering design, project management and field service from its headquarters in Fort Pierce, Fla. Aerex® field service personnel ensure proper operation of the system and provide complete training on all aspects of the system including operation, maintenance, cleaning and troubleshooting.
