Maintenance of Brine Transparency in Salinity Gradient Solar Ponds

摘要

Experience with maintenance of brine transparency during the more than eight years of operation of the 100 square meter Research Salinity Gradient Solar Pond at Argonne National Laboratory suggests that, for many sodium chloride brines, algal growth may be readily curtailed by minimizing the phosphate content of the brine. The use of modest amounts of aluminum sulfate (<5 gm m/sup /minus/2/ yr//minus/1/) to precipitate soluble phosphate has resulted in a reduction of the use of chlorine from 13 gm m/sup /minus/2/ yr/sup /minus/1/ to 2.8 gm m/sup /minus/2/ yr/sup /minus/1/, while maintaining good transparency in the pond brine. 20 refs., 3 figs.
