New Delhi: A team of researchers at the Indian Institute of Technology (IIT) Ropar has developed an innovative Nano Bubble (NB) generator. It will be useful in treating polluted water discharged from industries or at Sewerage Treatment Plants (STP).
As per IIT Ropar, the NB generator created by the researchers can be useful for farming and fishing in addition to wastewater treatment. It will reduce the operating costs of Sewerage Treatment Plants (STP) by 50% of the recent cost.
In addition to this, It can be applied to drip irrigation and agriculture, aquaculture and fisheries, pond and river restoration, gas and oil industries, sterilisation, the medical field and cleaning and disinfection processes without surfactants and chemicals.
According to the IIT Ropar researchers, a 3KW nanobubble generator can also be powered by solar energy if it is used for fishing, while a 20KW generator can be utilised for wastewater treatment at a 5 MLD STP.
Informing about the development, Neelkanth Nirmalkar, Assistant prof, Chemical Engineering Department at IIT Ropar stated that these nanobubble generators are being produced by IIT Ropar startup Nanokriti, and the technology will be made available to the manufacturing sector for commercialization in the event that demand for generators increases.
The approximate cost of the 3 KW NB generator is Rs 50,000, whereas the approximate cost of the 20 KW NB generator to be deployed at STP is Rs 5 lakh. With the use of this NB technology, the current electricity costs for water treatment at STP or in the industry will be cut in half.
Neelkanth Nirmalkar said, “The discharge of chemicals in river waters is a major source of water pollution and the textile industry is a major contributor to it. To degrade chemicals in the water, ozone or oxygen is required and this generator will make it possible at a cheaper cost".
"The treatment procedure including the degradation of chemicals, presently being run by the industry is having high running costs following which the industries allegedly escape from treating water but this NB technology will reduce the treatment cost to half", he added.
