Iran purifies wastewater using nanotechnology

A graywater purification device, which is made based on nanostructured ceramic membranes, has recently been unveiled at a nanotechnology exhibition in Tehran.

The water purifier has been designed and built on several stages of filtration and ultrafiltration. The machine has several nanoscale ceramic membranes with different pore diameters, IFP wrote on Wednesday.

The device was unveiled on the sidelines of the 11th International Nanotechnology Exhibition, during a ceremony attended by Iranian Vice President for Science and Technology Sorena Sattari.

Ali Akbar Babaloo, the managing director of Nano Industry Researchers Company and a faculty member at Sahand University in Tabriz, has talked about the performance of the device.

“Due to the high precision of the pore size of the membranes, this device can purify graywater and turn it into microorganism-free water. In the future, it can even be used to produce drinking water.”

Regarding the domestic and foreign samples of this machine, he added, “For the time being, some European companies are producing ceramic membranes, but given the country’s economic circumstances, our product will be much more cost-effective than its foreign counterparts.”

“Given the fact that the raw material required to produce these membranes and its technical know-how is available in the country, producing such devices seems very cost-effective due to the critical conditions of water in the country. It can reduce the severity of this crisis. This device is currently being developed in a carwash and three other places.”

Referring to the commercialization of the product, Babaloo said, “In the coming months, with the help of investors, the number of the company’s products will increase, and we will be ready to provide services to residential complexes soon.”

According to Babaloo, the price of the device for a residential complex of about 30 units would be about 300 to 400 million rials. Furthermore, as the filters used in this device are washable, there is no need for annual or monthly replacement of filters; therefore, it would be very cost-effective to purify graywater.

Kitchen and laundry wastewater, carwash and carpet wastewater are samples that can be used for irrigation of greeneries, farming, and even filling flash-tanks.

The 11th edition of the Nanotechnology Exhibition, also known as Iran Nano 2018, kicked off in Tehran on Saturday with the participation of 160 institutions.

According to Hamed Afshari, the secretary of the exhibition, 28 technologies that can attract investments were featured in this year’s exhibition.

Nano is a new and up-to-date science in the world.

Iran entered the field 15 years ago, and today it is one of the countries manufacturing nano-based products.

According to Web of Science, Iran ranks fourth in the world in nanotechnology, having published 8,791 articles in the field in 2017.

Iran holds fourth place, after China, USA, and India.
