7.5 SOLAR PONDS - APPLICATIONS
7.5.1 Heating
In the past solar ponds have been used for water heating and in some cases also
for industrial process heating. Solar ponds have the highest potential in suitable
applications and locations to supply low-temperature heat at competitive costs. The
suitable heating applications of a solar pond are town water heating, salt drying, fruit
drying, wood drying, hot water for the food industry, solution mining operations
(Hull, 1989).
7.5.2 Aquaculture
Pyramid Hill solar pond has been used to supply low temperature heat for aquaculture
for growing warm water fish and shrimps. Solar ponds are suitable where the desired
supply temperature is low and a large amount of heat is required. Using fossil fuels
for supplying the low temperature process heat is not sustainable; hence solar ponds
should be used for heating aquaculture ponds to grow fish, shrimps, algae etc. The
heat from the solar ponds can be used for controlling the temperature of the environ-
ment for growth control well as to supply other thermal energy needs of the plant.
