Iran inaugurated the first advanced bio-tech industrial sewage treatment unit in the Middle East in Isfahan Province, central Iran.
The unit was piloted with treating 300 cubic meters of water daily in Isfahan, said Mohsen Eftekhari, CEO of Shahid Montazeri Power Plant in Isfahan.
The unit has lessened expenses by 50 percent and occupies less than 75 percent of space needed for ordinary ones. It also consumes 70 percent less time for filtration process.
In piloting process, the 1000-ppm industrial wastewater was changed to 70-ppm water, meaning that it can be used for watering trees, he said.
Using the method, only one fifths of sediment is made comparing to other methods of industrial wastewater treatment, and the sediment can be used in polymer-making industry as well, Eftekhari said.
The technology was introduced in the world in 2012 and 60 European cities have so far used the method for wastewater treatment.
