Iranian Knowledge-Based Firm Equips Wastewater Treatment Plant with Nanochlorine System
The company's nanochlorine technology helps increase the effectiveness of disinfection and reduce the pollution of water resources by producing and distributing chlorine in nanoscale.
This system is now being used in Takestan City’s Wastewater Treatment Plant in Northern Iran and can also be used in other treatment centers.
“We have been able to produce chlorine in nanoscale and distribute it evenly in the wastewater. This has enabled the chlorine to be distributed well throughout the entire volume of water,” said Aref Dadgostar, the managing-director of the company.
He stated that increasing water quality and reducing chlorine consumption are among the most important advantages of this technology, and noted, “In the past, this treatment plant used an average of 100 liters of disinfectant per hour but now this number has been reduced to 70 liters per hour. This reduction has resulted in a 30 percent saving in chlorine consumption.”
“This system has also reduced the amount of residual chlorine in the wastewater to only half a milligram per liter; meaning that the chlorine has had its effect and does not harm the nature,” Dadgostar said.
In a relevant development in January, Iranian researchers at a knowledge-based company succeeded in indigenizing a hydrodynamic nanobubble device which can treat industrial wastewater with high efficiency and low cost without any problems for the environment and does not need any additives.
“This device uses nanobubble technology to treat wastewater. In this technology, nanobubbles are produced and, after exploding, they create mechanical waves that are capable of eliminating suspended particles in wastewater,” said Majid Boujaran, the chairman of the Board of Directors of the knowledge-based company.
Also, Seyed Amir Abbas Kashanchi, the technical director of the company, explained that the device can eliminate organic matter and pigments, enzymes, and microorganisms, adding that the technology can also be used for desulfurization of oil and arsenic removal from water.
“The COD factor (chemical oxygen demand) is one of the most important and fastest methods in the study and control of wastewater treatment systems. This device can convert the wastewater with 20,000 COD to 8,000 COD,” he said.
