Experimental results are reported for the continuous evaporation of sa
line water under enhanced solar energy input. A multipurpose solar des
alination unit (MPSDU) has been introduced and tested. A dynamic flow
of saline water introduced to the multi-channel evaporator is heated u
p to 60-degrees-C. Soluble mineral salts are selectively separated alo
ng the channels in addition to distilled water. The salts include NaCl
, MgCl2 and others.
