Iranian Researchers Develop New Water Softener
“Nitrate in water is considered as a pollutant due to its proven negative effects on human health, and since nitrate is dissolved in water as a solute, the normal water purification methods are not able to remove it. On the other hand, nitrate is constantly produced and dissolved in underground water resources. The most important technology in the world in this field is Electro Dialysis (ED),” Mansoureh Zahedi, head of the research and development department of an Iranian knowledge-based company said.
Zahedi pointed to removal of arsenic in water as one of the other capabilities of their company's purification machine, saying “One of Iran's challenges is the presence of a high level of arsenic in water. Our device can remove arsenic from water.
She said that her company's machine is solar powered, adding, “These devices use nano absorbents to purify water and wastewater.”
The researcher also pointed to removal of oily wastewater pollution as one of the other capabilities of their machine, explaining, “Oily wastes are produced in industries such as oil, petrochemical and food industries and are mainly in the form of oil-water emulsions. Due to the long-term durability of these wastes in the environment, if they are not eliminated, they will leave unfixable and extensive damages on environment, that is why we have proposed a package to remove oily wastewater pollution.”
Zahedi went on to explain that in her knowledge-based complex they produce air nanobubbles to remove oil pollution such as oil or grease from the surface of the water.
She further said that lack of chemical substances, minimal electric current consumption, durability of performance with respect to temperature and pH conditions, ease of maintenance and use, small occupied space, and the ability to reuse waste water in her company's production process as other advantages of their product.
