Full Description

The design of a new 8-million-gallon-per-day (MGD) water treatment plant for South BlountCounty Utility District (SBCUD) utilized microfiltration (MF)/ultrafiltration (UF) membranes.Several manufacturers can provide MF/UF membrane systems. However, all of these systems areconfigured and operate differently. Once a membrane system is selected, future replacement ofmembrane modules will be limited to the one manufacturer. The configuration of thesemembrane systems also would require different building footprints to house them. Therefore, aRequest for Proposals was prepared to select a system around which to design. The selectionprocess included a ranking of proposals based on both economic and non-economic criteria.Negotiations were then made with the highest ranked manufacturer to determine the final cost,scope of supply, schedule of delivery, and future replacement guarantees. This approach allowedSBCUD to procure a membrane system for a competitive cost and select a system that best mettheir needs while providing guarantees for future membrane replacement costs. Design costswere minimized since the membrane system was selected prior to design. Includes tables, figures.
