15 June 2021 Current Affairs:A new technology developed by a professor in the Department of Chemical Engineering of Jadavpur University in Kolkata can reduce the cost of small and medium-sized enterprises.

♦ The new technology uses a combination of Electrocoagulation and ElectroflotationEenhanced Membrane Module (ECEFMM) technology for wastewater treatment.
♦ Electrocoagulation is a wastewater treatment technology that uses electric charge to change the surface charge of particles, causing suspended matter to form aggregates.
♦ Electroflotation is the process of separating suspended particles from water by using hydrogen and oxygen bubbles created by passing electricity through water.
♦ The innovation has a good market potential because it is an economically feasible wastewater treatment technology (both in terms of capital and recurring investment) for small and medium-sized businesses. 
♦ Furthermore, unlike other conventional treatments, it can break the highly stable oil-water emulsion through electric discharge while simultaneously separating oil from water with high efficiency.
♦ The technology was created with the Department of Science and Technology (DST) assistance, Government of India's Advanced Manufacturing Technologies programme.
