A solar powered water desalination plant is introduced by the students of Energy Engineering Department, Hamdard University (HU) in Karachi, in order to handle the drinking water shortage problem in Pakistan.

Under the supervision of Chairman of department, engineer Akmal Hasan, the plant was developed by the students Aziz Rasheed and Hamza Asgher.

A fine quality glass was used, which was after cutting fixed in with silicon in pyramid shape, as told by Aziz. He further added that “Two steel trays have fixed together in form of large tray in such a way that two separate ways for flow of polluted and desalinated water could be developed. Polluted water enters in central tray through PVP pipe where it changes into vapors due to sunlight. The vapors gather at glass walls where they turn into water drops again which flow through walls to outer tray where desalinated water is collected through PVP pipe.”

This water could be used for drinking and daily usage, as viewed by Aziz.

He further said that while keeping in view the power shortage in the country, for electrical plants, the best alternate are the solar desalination plants.

Without seeking any expertise abroad, the students of the University designed it themselves. It cost is only Rs.250, and in the local market, all parts of the plants are easily available. In 12 hours, the prototype plant can desalinate 24 liters of water. It is of very low cost and easy to use.
