Nano-Based Treatment Device Reduces Pollution of Industrial, Domestic Wastewater in Iran
The device developed by Pishro Fanavar Nano Tav Asia company is useful in destruction and neutralization of organic pollutants in industrial, mining, domestic, etc. wastewater, treatment of hospital effluents containing dangerous compounds and treatment of contaminated and toxic waters with heavy metals and microorganisms.
Among the advantages of this device mention can be made of the ability to destroy highly stable materials, the small amount of space needed for the treatment process, no use of chemicals, cost reduction compared to similar methods, removal of heavy metals and reduction of producing voluminous sludge.
In this device, the combination of plasma and cavitation technologies has been applied for the treatment process. Meantime, the pulsed plasma section provides an environment prone to the destruction of pollutants by creating an electrical discharge in the water.
In a relevant development last month, Iranian scientists at the University of Tehran used a scientific method to treat the wastewater of alcohol-making plants to produce food for aquatic animals.
Arash Javanshir, a faculty member of the Agriculture and Natural Resources Department University of Tehran, used a method based on performance of the particle capture system and treated wastewater and recycled water from the effluent resulted from alcohol production, and could treat the polluted wastewater of alcohol-producing plants to make food for aquatic animals.
“Treatment of this wastewater and the protein in the obtained sludge is not only suitable for the food diet of aquatic animals, but it will also lead to purification of water and returning it for reuse in plants and reduction of water consumption,” he said
Warning that the wastewater is harmful to plants and animals due to the existence of the hydrogen sulfide gas,” Javanshir said, adding if all plants use this system, they will help both in decreasing water and electricity consumption and keeping the environment clean.
