Participation of SMTRG in the Persian Gulf Water Desalination Project funded by the Johannes Gutenberg University of Mainz, Germany.
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.
ceremony of Unveiling water hardness reducing device On 11 th Dec. 2020, during a ceremony attended by the CEO of Bushehr Water and Sewerage Company, the water hardness reduction device was unveiled at the Faculty of Oil, Gas and Petrochemical, Persian Gulf University. In this ceremony, a water hardness reduction device was unveiled in the laboratory of the Sustainable Membrane Technology Research Group (SMTRG).The project is managed by Dr. Mohsen Abbasi, a member of the research group and of the Faculty of Petroleum, Gas and Petrochemicals of the Persian Gulf University, who completed the project with the financial support of the Bushehr Water and Sewerage Company. In this ceremony presented the PGU president and PGU Vice Chancellor for Research & Innovation.
SMTRG hosted Dr. Vahdati on the topic of “Soft adhesives based on weak interactions with application in aqueous environments “. The 68th series of international elite scientific conferences was held on Tuesday, October 27, at 3:00 PM. Dr. Vahdati currently doing his postdoc in Sorbonne University in France.
Soft underwater adhesives based on weak molecular interactions comprise a rapidly emerging field of research. Although the majority of recent literature on underwater adhesion has focused on strong (covalent) interactions, recent insights into the critical role of weak interactions in organismal adhesion in biology has inspired researchers to incorporate these interactions into bulk synthetic and biomimetic model systems. Soft adhesive materials often need to balance bulk mechanical properties and effective bond formation to offer tuneable, rapid, and in many cases reversible underwater adhesion. Without the need for chemical crosslinking reactions potentially dangerous to human health, soft underwater adhesives are promising candidates for various biomedical applications.
I am a researcher in the field of physics and chemistry of soft matter, a large family of materials spanning many food and cosmetic products (emulsions, etc.), polymers, as well as living tissues. My main research interests are structure properties relationships in soft matter and smart, bio-inspired materials. The first area deals with understanding the physical and mechanical properties of soft materials as a function of their structure at small (micro and nano) scales. The latter regards learning lessons from natural systems and organisms and applying them to engineering and materials science problems. Currently I am a postdoctoral researcher in IS2M where I work on the development of surgical adhesives in collaboration with a biomed startup. During my PhD in polymer physical chemistry at ESPCI Paris, Sorbonne University, I studied bio-inspired, soft hydrogels as underwater adhesives. In both undergrad and masters, I majored in polymer engineering in Amir Kabir University of Technology.
On October 1, 2020, a joint webinar of the Persian Gulf University and Bushehr Province Water and Sewerage was held on the topic of new technologies in seawater desalination.
In this webinar, first of all, Engineer Abdolhamid Hamzehpour, CEO (Chief Executive Officer) of Bushehr Water and Sewerage Company, presented a report on the latest status of water desalination plants in Bushehr province and upcoming programs. Then he stated that 80% of drinking water resources in Bushehr province are supplied from neighboring provinces and this is while most cities of Bushehr province are coastal and about 700 km of coasts of Bushehr province are next to the Persian Gulf, so there is an urgent need to provide drinking water in the province from the sea water resources. Finally, he reported on the joint programs implemented with the Persian Gulf University.
Then Dr. Seyed Abdollatif Hashemifard, Head of the Faculty of Petroleum, Gas and Petrochemical Engineering (FPGPE) as well as the head of the Sustainable Membrane Technology Research Group (SMTRG)of the Persian Gulf University (PGU) presented a speech on the situation of water resources in the world and Iran, common membrane processes in desalination, membrane distillation process, introduction of semi-industrial distillation pilots , Membrane distillation membranes, etc. with the focus on membrane distillation technology for fresh water production. Finally, they stated the advantages of membrane distillation processes compared to common processes in the world.
Then, Dr. Mohsen Abbasi, a professor at Persian Gulf University and members of Sustainable Membrane Technology Research Group (SMTRG), explained the production of silicon carbide membranes for seawater pretreatment as a pretreatment step for RO plants, which was first produced in the country in collaboration with the Persian Gulf University and the Bushehr Water and Sewerage Company.
