To Design a Low Cost Solar Desalination System for Karachi
Project Area of Specialization Mechanical EngineeringProject SummaryDesign and fabricate a desalination system capable of producing atleast 5 lites of fresh water per day from saline water through harnessing the solar radiations only. A mathematicl model also made to pedict the perfomance of the system.
Project Objectives1. Atleast produce 5 Litres of fresh water per day.
2. Make a mathermatical model to predice the performance of the system.
3. Make the system portable
4. Make the system modular i.e. increse the components according to water and weight requirements
Project Implementation MethodStart with comparing with existing systems of similar nature. Select a a system that meets the above criteria. Perform research on improviing the selected system. If feasibe; make a mathematical model; if successful fabricate the systema and match the results to validate the model.
Benefits of the ProjectProvides a mode of survival for coastal regions or regions with brackish water. Beneficial to any regoin where having no electric source especially on naval ventures.
Can also be modified to increase the yield according to the need or fit in fornt of the any heat source other that the sun to produce the same reult such as the compressor of an air conditioning unit to recover the wated thermal eneryg.
Technical Details of Final DeliverableSize: 30 in x 30 in
Thickness; 2.5 in
Weight: <15kgs approx
Food Grade: Yes
Modular: Yes (Addition of more chambers results in highre yield)
Use life; 20 yeasr
Thermal efficeincy; approx. 170% (sice waste thermal enegy is recoverd by subsequent chamber)
