TEHRAN (ANA)- Iranian scientists have found a new method by using nanotechnology to remove the unpleasant smell of sewage treatment plants and urban manholes.
“Kimiagaran Sanat Amirkabir company uses nanofiltration technology as a new method to remove smell of wastewater in sewage treatment plants and urban manholes,” said Seyed Mohsen Hosseini, the managing director of Kimiagaran Sanat Amirkabir company.
He also referred to the features of the nanoabsorbents used in the technology, saying that they enjoy porous structure, high absorption capacity, surface reactivation capability, selectivity and low price, adding, "The nanoabsorbents used in the technology can even be used in agricultural industry after the end of their lifespan."
In a relevant development earlier this year, an Iranian nanotechnology firm had also succeeded in making a soundproof pipe by using nanoparticles with application in construction industry.
‘Hamid Group’ is the company which produced the silent pipe which is comprised of three layers, with the middle layer made of a nanocomposite material.
There are both nanoparticles and microparticles present in this layer enabling desirable mechanical properties and optimized acoustic properties.
The use of nanoparticles in the polymer matrix in the intermediate layer has led to higher hardness and stiffness and enhanced acoustic properties.
The special sewage pipes can be used in insulation of fittings and construction projects.
