TEHRAN - An Iranian knowledge-based company in cooperation with Khorassan Razavi province’s water distribution company implemented the first phase of Bajestan desalination project by using advanced RO-EDR technology.
The first phase of one of the important drinking water supply projects in Khorassan Razavi province in Bajestan city was successfully designed, implemented and put into operation by a knowledge-based company active in the field of nanotechnology. This project aims to settle the problem of the water shortage crisis and improve the quality of drinking water in the arid regions of the country, and has been implemented.
In this project, using modern technologies of reverse osmosis (RO) and selective reverse electrodialysis (EDR), two separate treatment lines with a total capacity of 3,000 cubic meters per day have been designed. This system has a net efficiency of 85% and, while providing a sustainable supply of drinking water, reduces dependence on groundwater extraction.
EDR technology, as one of the new technologies in the water treatment industry, enables the recycling of concentrated saline wastewater and, along with RO technology, has significantly increased the efficiency of the system. PNF company, as one of the pioneers in the use of EDR technology in the country, plays an important role in the development of this technological approach in the water treatment industry.
In a relevant development in April, a technological team at Tarbiat Modarres University designed a nano-based floating desalination device that can turn salt water into drinkable water in 8 hours without the need for electrical energy.
“This floating desalination device can be placed on the surface of salt water in the sea or pond and produce drinkable water by using sunlight without the need for electrical energy,” said Muhammad Saber Sharifi, a member of team.
“This device can produce between one and two liters of fresh water in 8 hours, meeting the daily drinking water needs of an adult,” he added.
Sharifi noted that nanotechnology is used in the product, saying, “Photothermal materials were used in manufacturing this device, and when exposed to sunlight, it creates a thermal reaction, leading to evaporation of water and ultimately its desalination.”
