Towered Desalination Plant Built in Pakistan
In 1993 a desalination plant was invented by Akhter Iqbal Zuberi in Pakistan. Zuberi’s plant produces 40 liters of water per square meter per day. This is at least ten (10) times more productive than a conventional Horizontal Solar desalination plant. Water desalinated from this plant has 16 parts per million (ppm).
The structure is a raised tower made of cement, with a tank at the top. The whole plant is covered with glass of the same shape, but slightly larger, allowing for a gap between the cement tower and the glass.
The tank is filled with saline water and water from an outside tank, drop by drop water enters the inner tank. The excessive water from the inner tank drips out onto the cement walls of the tower, from top to bottom. By solar radiation, the water on the wet surface and in the tank evaporate and condense on the inner surface of the glass cylinder and flow down onto the collecting drain channel. Meanwhile, the concentrated saline water drains out through a saline drain.
The Karachi Port Trust (KPT) Manora Water Desalination plant was has inaugurated in 2011 to provide between 200,000 to 250,000 gallons of water per day to residents of Manora, the Pakistan Navy and harbouring ships. Installed through a joint venture, including Turkish firm Aritim Mühendislik, the project includes membrane filtration technology and was completed at an investment cost of Rs. 140 million ($1.5 million).
This is not Pakistan’s first desalination facility. One of the country’s first was the Power & Desalination Cogeneration Plant commissioned between DHA Cogen, a company set up under a joint venture between the Defence Housing Authority (DHA) and Messers Sacoden from Singapore. Sweden’s Alfa Laval provided the desalination units while Siemens of Germany delivered the combined cycle power plant.
The 94 MW plant was slated to produce three million gallons per day of desalinated water, through multi-effect desalination evaporation technology. Following the commission, however, the project has faced reported financial and technical problems.
In 2015, the Desalination Complex in Mithi in Tharparkar was inagurated. It is the Asia’s largest solar desalination plant complex completed by the energy department of the provincial government. The plant will provide 8 million litres per day of drinking water in addition to producing one mega watt of electricity, benefitting the people of Mithi city besides other 100 villages.
