✦ Synopsis

The Solar Pond encr~ collector is proposed as a mans of utilizing sotar energy for the coriccntra-Zion of rcjcst brincz from inland bawd clcctrodint?s~s piants. For such piants. conixntmtc dispo~%i ma) be a serious problem. The So& Pond, x\hich is a stabic stratified s)stcm containing so&urn chlorrdc solutions which incmw rn dcnslty \ith depth, itill coltcct solar energy xtd its bottom lager Hill heat up to tcmpcraturcs as high as 90 C and more. Thrw bottom layers arc continuously cvqxxWcd in a \acuurn chamber tnd the vapors condensed in thr feed watrr to the eltitrodialysis plant. This ~sults m a l&Z0 fold concentration of the brine; an increajc in operating tcmpcfaturc of the elcctrodtaI)sis plant nzsultirtg in IOHW energy rcquircmcnts. The prcxxss is described. The resuit;mt brincz can be used to rcgcncmtc a ation exchanger uhich prbwftens the raw f&d water to the plant, making the process \irtu& s&c-free. Dcrstb are giwn c;f an experimental study of such a process carried out on 3 tutu& Mine %tRr. and results presented for a material baIancc and economic e~afuarion.
