Technology from Turkey and Qatar came together! Sea water will be an alternative

Istanbul Technical University (ITU) will turn seawater into drinking and utility water with 40% lower costs and environmentally friendly methods, using hybrid technology that includes thermal and process methods of seperation.

ITU Faculty of Civil Engineering Department of Environmental Engineering Lecturer Assoc. Dr. Derya Yüksel İmer and his team have initiated a study to transform seawater into drinking and utility water at a lower cost, using sustainable and environmentally friendly techniques, within the framework of international cooperation between Turkey and Qatar.

In this context, the team aims to transform low-quality, high-salinity seawater into drinking and utility water at lower cost and higher efficiency through hybrid thermal and separation technology.

Hamad Bin Khalifa University, Environment and Water Institute and Gebze Technical University, Assoc. Dr. İmer’s “Development of Advanced Membrane Distillation Technology for the Treatment and Desalination of High-Salt Seawater” project, led by İmer, was awarded joint support of $540,000 in the under the priority research program of the National Research Fund of Qatar.

Assoc. Dr. In his statement to AA Correspondent, İmer said that water scarcity is a fundamental problem all over the world and appropriate technologies for alternative water resources should be developed.

Stating that the severity of industrialization in the world, population growth and climate change are increasing the pressure on water resources, İmer said, “In particular, the amount of clean and accessible water is decreasing day by day. water in the project.” mentioned.

Expressing that in the project, the team from Qatar and Turkey is trying to bring together the technologies whose reliability is determined in terms of obtaining water from the sea, and continued as follows:

“Thanks to the experience gained by the Qatar team during some previous pilots and field studies on thermal desalination technology, we also have nanofiber materials and high efficiency filters that we use in some separation processes that we have developed at ITU. Therefore, with these two synergies, we currently have thermal and separation processes. We will carry out this project with a double-layer technique that we call technology. The ultimate goal of the project is actually to provide drinking water and high efficiency utilities from sea water. We can get very high efficiency water with thermal systems, but the biggest drawback of these systems is of course the cost.We take advantage of these technologies.We will ensure that up to 90% of the input quantity is obtained in clean water by combining the disadvantages of


Imer noted that when turning seawater into clean water, a large amount of salt is returned to the sea.

Expressing that this situation negatively affects the marine ecosystem, İmer said, “With the technique we will develop in our project, the flow returning to the sea will not be pressured on the ecosystem, and it will be controlled with a more environmentally friendly, more sustainable management approach. Therefore, we are actually trying to develop a fully environmentally friendly and sustainable desalination technology.” he said.

İmer pointed out that the clean water they get from the sea can be used in all areas.

Emphasizing that using sea water will be a solution to water scarcity, İmer said, “The biggest problem of every country in the future will be water scarcity. Therefore, water seawater is a very good alternative for this. Our goal is to be ready for these technologies at field scale at the end of our project work which will last three years, and be able to keep seawater readily available as an alternative water source in the event of a potential water shortage used phrases.


Explaining that obtaining drinking water is an expensive activity and a significant amount of energy is used, İmer said:

“With the hybrid technology we plan to achieve here, we have determined that we have reduced the cost by 40% in preliminary studies conducted at the scale of thermal and separation processes. Our goal is to reduce this cost even further and to try to make the unit cost of water economically advantageous. Not only will we convert it, but we will also reduce the amount of energy consumed when converting that water.”
