Iran-Made System Treats Most Hazardous Wastewater of Petrochemical Industry, Refineries
“This product is a system for purifying and neutralizing used caustic which has an important and vital application in the oil and petrochemical industries,” said Ali Pour Khalil, the managing director of the knowledge-based company.
Noting that his company is active in manufacturing membrane systems for degassing and water gasification with the aim of producing high-quality water and wastewater treatment for various industries in Iran, he said that in its latest research, the company has succeeded in making the caustic wastewater neutralization system.
Pour Khalil stated that the used caustic is one of the most hazardous parts of the effluents of the refining and petrochemical industries with the highest degree of pollution, adding, “In this treatment method, nanocomposite membranes are used. The input of this device is wastewater that has a strong base, and when this wastewater enters the device, first the neutralization process is implemented and its pH reaches the pH of pollution-free water, and then the process of removing pollutants dissolved in the wastewater like TDS and COD starts.”
Also, in November, specialists at an Iranian firm had managed to find a new method to use nanocomposites to treat spent caustic discharged from refineries and petrochemical companies.
“We produce membrane contactors by using nanocomposite technology. Our technology is a novel technology in the world and we have some patents, PCT patents and US patents,” Hassan Farrokhzad, a director of Setaregan Noavar Sepehr Pars company, told ANA.
“By this technology, we can introduce the gases inside the water and it is very useful for treatment of spent caustic which is a discharged liquid from refineries and petrochemical companies and we can treat this spent caustic in the normal and ambient temperature and it is one of the advantages of this technology compared to other technologies used in the US and Germany,” he added.
“We have plans to export our products but at the moment we are using this technology in the Iranian refineries and petrochemical companies," Farrokhzad noted.
