OF SS EFTA00807651 OVERVIEW Gemini Seawater Systems LLC (GSS) is pleased to present this proposal for the design, fabrication, installation and commissioning of a 25,000 gallon per day (GPD) seawater reverse osmosis desalination plant for The Saint James Group to supply water for Great St. James, USVI. This system will be supplied in a modified 20-foot-long shipping container. It is our understanding that this plant will provide water for the island until a subsurface pipeline is installed from Little St. James Island at which time the system could be decommissioned and sold or could remain on the island to serve as a standby water supply. The overall treatment process will consist of seawater pumping from the existing intake, media filtration, cartridge filtration, the addition of a trace quantity of a scale inhibitor, membrane separation, and post treatment consisting of upflow calcium carbonate for the addition of an alkalinity and hardness followed by chlorination. Disposal of the membrane concentrate and media filter backwash, will be via the existing outfall. The desalination system will consist of a single skid mounted unit rated to produce 25,000 US GPD within a 24-hour day. It will consist of two pressure vessels, each designed to hold up to three Toray TM820M- 400 spiral wound elements. The system will be designed to incorporate an automatic flushing feature that reduces the chance of scale formation or equipment corrosion during periods of shutdown. The proposed membrane feed pump is a Danfoss APP8.2 positive displacement axial piston pump constructed from 2205/2507 duplex stainless steel. Operating in parallel with the membrane feed pump will be a single ERI energy recovery device. This design provides the lowest possible energy usage and the greatest degree of flexibility, while maintaining a residual pressure on the membrane concentrate to eliminate the need for re-pumping for disposal. All low-pressure piping systems will be constructed using schedule 80 PVC, while all high-pressure piping is made from Zeron 100, a high quality super duplex stainless steel developed specifically for seawater. The plant controls are identical to those being installed on the Little St. James unit, designed to allow monitoring and control of each individual unit process from the control panel or remotely via a broadband Internet connection. The control system will be PLC based with a touch screen interface. The overall plant includes all the necessary instrumentation, motor starters, and controls for a complete, integrated system. The membrane post treatment process included in this proposal consists of one calcite bed and one liquid chemical feed system for disinfection of the finished water. OEM7J17. SEAWATER SYSTEM I-I-C PACE S OF MI EFTA00807652 Based on the stated assumptions for feedwater quality, this plant will produce finished water with total dissolved solids (TDS) in the range of 350 to 500 parts per million (ppm), well within US Safe Drinking Water Act. The system would be furnished in a new 20 foot-long shipping container modified to include 2-inches of insulated refrigeration panels, lighting, man door, and split air conditioning unit. The exterior of the container will be painted white to reduce heat loading, but the color could be changed to blend the container into the nature colors of the island. The price for the entire system is US$213,810, FOB Gainesville, Florida. This price includes a new seawater intake pumping system, pretreatment, 25,000 GPD SWRO unit, post treatment, installation tools and labor, commission labor and consumables and operation and maintenance manual. This price does not include the seawater intake, outfall, storage tanks or field piping and conduits, trenching and restoration cost. CEM7J47. SEAWATER SYSTEM I-I-C PACE LI OF MI EFTA00807653 PERFORMANCE PARAMETERS In the proposed plant design, seawater will be obtained from an open seawater intake located on the south side of the island and treated to US SDWA Standards. The proposed desalination process was developed based on a membrane flux rate' of 10.4 GFD. All hydraulic loading rates and pipe sizing have been done assuming a maximum recovery rate2 of 40 percent. Table 1 summarizes the design criteria used to size the proposed equipment.

A 40 percent recovery system produces 40 gallons of permeate for every 100 gallons of seawater pumped into the membrane array. 3 Detailed breakdown for the estimated power consumption is presented on the next page.

During the RO process, the dissolved solids, including these sparingly soluble salts, are concentrated by the RO membranes. If any of these salts are allowed to precipitate, the resulting scale can foul the RO membranes. Through the use of scale inhibitors, the potential for the seawater to form a scale during the treatment process is minimized.

This added injection of low salinity water further reduces the potential for corrosion within the high pressure and energy recovery booster pumps. For periodic cleaning of the membrane elements, the permeate storage tank and flush pump are used to recirculate cleaning solutions through the pressure vessels.
