Iranian Student Makes Sludge Removal System to Protect Environment
“Sludge collecting device for all types of algal and sediment pollution can reduce damage to technical and environmental facilities and keep the entrance to facilities of water stations healthy,” said Jalal Mirzayee, the manager of the project.
Noting that the device can be installed at the entrance of all types of water pumping stations and dams and all kinds of water storage sources, he said that the system cleans the filter of water entrance without the presence of an operator deep in pumping stations.
“The device's mechanism of action prevents reproduction and formation of any type of algae and the deposition of water salts in pumping stations," adding that the mechanism is useful to the environment,” Mirzayee said.
In a relevant development earlier this year, a wastewater treatment device based on the synergy of plasma and cavitation technology was designed and manufactured by a knowledge-based nanotechnology company in Iran which is able to treat all types of wastewater and recycle them for reuse.
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.
