Low and medium-scale enterprises in automobile, meals, and other sectors would quickly have access to a new wastewater remedy technologies that would decrease the higher charges of current technologies for handling oily wastewater generated at their supply points. The new technologies, which consists of an cost-effective electric field-assisted membrane separation device for oily wastewater remedy, is created by Dr Chiranjib Bhattacharjee, Professor at the Chemical Engineering Department in Jadavpur University, Kolkata. Built with help from the Advanced Manufacturing Technologies programme of the Department of Science & Technology (DST), the technologies functions on a mixture of Electrocoagulation and Electroflotation Enhanced Membrane Module (ECEFMM) methods for wastewater remedy, Science and Technology Ministry stated in a statement.
While Electrocoagulation makes use of electrical charge for altering the particle surface charge, permitting suspended matter to type aggregates, Electroflotation separates suspended particles from water applying hydrogen and oxygen bubbles generated by passing electrical energy via water, the ministry noted. “So far, the separation technology running in different sectors for treating such oily wastewater involves the installation of an electrolytic cell or DAF followed by membrane unit. However, installing two separate units requires a high footprint area compared to the present unit, where two-unit operations are being assimilated in a single unit, said Dr Bhattacharjee.

Due to the high cost of existing technologies, a large amount of untreated oily wastewater is discharged into the aquatic bodies without following the guidelines of the Pollution Control Board. However, the new technology is feasible in terms of capital and recurring investment for low-scale and medium enterprises and has a “good market potential”. By integrating the “Electrochemical process setup with the membrane module in a single hybrid ECEFMM setup, one process has been eliminated. This significantly lowers the initial capital investment expense along with the additional advantage of reduced installation area requirement.”
Moreover, the new technologies needs minimal manpower and does not will need higher-finish technical adequacy for its operation that cuts the operational expense to a big extent. The government stated that the recovered spent oil can be utilised as an industrial burner oil, furnace oil, mould oil, hydraulic oil, and so on., which would lead to income generation scope for low-earnings groups.
