SUA LPRO Interstage Boost & Energy Recovery

Under a Continuing Design-Build Services Contract with the SUA, Globaltech provided Project Management for Engineering and Design/Build activities related to the Low-Pressure Reverse Osmosis (LPRO) system at Hood Road Water Treatment Plant (WTP) Globaltech’s scope included managing crew and site resources, procurement oversight, coordinating activities with the Owner’s operations, and providing startup services. The project involved selecting and replacing membrane elements for the low-pressure reverse osmosis (LPRO) membrane skids to enhance operational efficiency. It also included the installation of new turbo energy recovery devices between the membrane stages and reconfiguring the interconnect piping. As part of this upgrade, the membrane pressure vessels were replaced to improve the pressure rating and incorporate a pressure control mechanism, ensuring optimal performance and reliability of the system.

Project Achievements / Benefits
  • Addressed raw water quality degradation issues in Floridan wells affecting permeate water by combining hybrid membrane element selection with energy recovery devices (ERD). 
  • Reduced system complexity and operational costs using ERD instead of booster pumps.
  • Enhanced system safety by accurately calculating required pressure ratings for all system components and replacing materials due for maintenance to improve reliability and efficiency.
