MSME - A ‘Make in India’ solution for waste-water treatment likely soon; know more about this cost effective, revenue generating innovation

Good news for automobile servicing industry, food industry and other low and medium scale enterprises. Soon they will likely have a smart, affordable electric field-assisted membrane separation device at their disposal for oily waste-water treatment.

Dr Chiranjib Bhattacharjee, Professor at the Chemical Engineering Department in Jadavpur University, Kolkata has developed a technology which uses a combination of Electrocoagulation and Electroflotation Enhanced Membrane Module (ECEFMM) techniques for waste-water treatment, a government release said.

The innovation being an economically feasible wastewater treatment technology (both in terms of capital and recurring investment) for low-scale and medium enterprises, has a good market potential, the release said.

Electrocoagulation is a waste-water treatment technique that uses electrical charge for changing the particle surface charge, allowing suspended matter to form aggregates, and electroflotation is the separation of suspended particles from water using hydrogen and oxygen bubbles generated by passing electricity through water.

This technology developed with support from the Advanced Manufacturing Technologies programme of the Department of Science & Technology (DST), Government of India requires minimal manpower and does not need high-end technical adequacy for its operation, thus reducing the operational expense to a large extent, the release said.

The recovered spent oil after oily wastewater treatment can be further used as an industrial burner oil, furnace oil, mould oil, hydraulic oil and so on.

The solution will likely create a huge revenue generation scope for low-income groups by selling this collected spent oil, the government release said.

It is aligned with the ‘Make in India’ initiative. The validation and testing of the prototype have been successfully accomplished, and the pilot-scale validation and testing is on the verge of completion, the release said.

This prototype innovation has proceeded towards level 6 of the Technology Readiness Level, and Dr Chiranjib Bhattacharjee has partnered with Concepts International for industrial collaboration and scale-up of the innovation, the release said.

He plans to further carry out a field run with the pilot-scale module, networking and field installation, and Commercialization of the equipment through start-up.
