The primary objective for this research is to ensure that this ocean floor system will produce asustainable quantity of water with a consistent water quality, along with providing informationto optimize the design for a full-scale facility. This project is divided into two scales of testing,pilot and demonstration. The pilot-scale testing used 8-inch columns; the results werepresented elsewhere (Allen, 2008), and will not be discussed here. The demonstration-scaletesting is being conducted at a near-shore facility, with two 5 feet deep pits (intake gallerywith a dimension of 60 ft by 50 ft, and discharge gallery with a dimension of 50 ft by 40 ft).The goals of the demonstration-scale testing are as follows:to determine the maximum intake filtration and discharge rate that can be sustained overa long-term period (up to 6 months); and, to evaluate the seasonal water quality impacts on the quantity and quality of waterproduced from the intake system and determine if further treatment is needed (i.e.microfiltration).The influent water qualities of the two sites are different and are presented in the paper. The rawdata are presented with microfiltration (MF) effluent quality from the prototype plant, whichserves as benchmark results for comparison of the feed to the desalting membranes.Although the ranges differ between the raw water qualities at the two locations, the averagevalues are similar. Includes 4 references, table, figures.
