Iranian Knowledge-Based Firm Produces Membranes for Water Treatment
Sina Maleki, a member of the board of directors of ‘Sepenta Polymer Sharif’ company, said that the membranes produced in his company can be used for wastewater treatment, gray water treatment and water recycling for membrane bioreactor systems, adding, “Flat membranes are less clogged than halofiber membranes and therefore, at present, they are used in most of wastewater treatment systems.”
It is worth to say that Membrane is used in water and wastewater treatment system as a phase through which the separated components in the solution pass at different speeds.
Given their wide application, these membranes are made of PVDF and PS polymers with special formulations and are used in various industries. Removal of dissolved solids, bacteria, viruses and other microbial substances from water is possible by this method.
Purification of drinking water or pre-treatment in order to remove turbidity, suspended solids, virus, color and some fine substances, disinfection of surface and underground water, production of industrial water from surface water, production of water from the effluent of urban and industrial sewage treatment plants will be possible by using the membranes.
In this process, there is usually no phase change and the products can be mixed together.The driving force required in membrane processes can be in the form of concentration, pressure, temperature and electric potential difference and makes the purification process possible.
Iranian researchers and knowledge-based companies have made great achievements in the past few years in various sciences.
Iranian Deputy Science, Research and Technology Minister Gholam Hossein Rahimi Sherbaf said last year that the country stood atop the regional states in scientific progress and development.
“Iran has ascended from the 5th rank to 1st in scientific progress in the region and from 58th to 16th in nanotechnology and from 52nd to 17th in biochemistry and bimolecular sciences in the world,” Rahimi Sherbaf said.
He also said that over 30,000 foreign students are studying at Iranian universities in MSC and MA courses, most of them from neighboring states.
“We rank first among the regional states in the development of science and technology as a pioneering country,” Rahimi Sherbaf said.
