The University of Johannes Gutenberg Mainz (JGU) is conducting an international research project to desalinate the Persian Gulf. The aim of this project is to improve water security in the Middle East. Teams from the University of Mainz, led by Professor Sebastian Seiffert from JGU and Professor Michael Maskos, also from JGU and head of the Fraunhofer Institute for Microengineering and Microsystems IMM, will participate in the BMBF project. Also, three partners from Iran and Iraq will cooperate in this project. Dr. Seyed Abdollatif Hashemifard from Sustainable Membrane Technology Research Group (SMTRG), Persian Gulf University (PGU) will participate in this project. In this project, temperature-sensitive polymer will be used to convert Persian Gulf Sea water into fresh water to supply water to remote areas. This process is energy independent and will be easily supplied by changing the day and night. The project will be carried out in two main phases: the first phase will focus on the development of optimized hydrogels and the synthesis of new membranes. In the second stage, a laboratory desalination setup is designed and built using the developed parts of the previous stage. The responsibility of this part of the project will be on the team of Dr. Hashemifard from SMTRG. Dr. Hashemifard is a member of the faculty of Petroleum, Gas and Petrochemical Engineering (FPGPE) of PGU and the head of SMTRG. This research group will be involved in the synthesis of direct osmosis membranes and the design and operation of a laboratory system. According to the forecasts, the device will be installed on the western campus of the university on the shores of the Persian Gulf, which is accounted as a turning point. During this three-year project, the exchange of doctoral and post-doctoral students, as well as the presence of researchers from both sides is foreseen. Therefore, considering the extensive physical knowledge of German researchers about the physical chemistry of polymer networks and thermal hydrogels, as well as the good experiences of researchers in Iran and Iraq in the field of direct osmosis technology, it is hoped that significant development will occur in this field.
