This DST-backed wastewater treatment technology to reduce costs for low, medium scale enterprises

The brand new expertise requires minimal manpower and doesn’t want high-end technical adequacy for its operation that cuts the operational expense to a big extent.

Low and medium-scale enterprises in vehicle, meals, and different sectors would quickly have entry to a brand new wastewater remedy expertise that would cut back the excessive prices of present applied sciences for dealing with oily wastewater generated at their supply factors. The brand new expertise, which consists of an reasonably priced electrical field-assisted membrane separation system for shiny wastewater remedy, is developed by Dr Chiranjib Bhattacharjee, Professor on the Chemical Engineering Division in Jadavpur College, Kolkata. Constructed with assist from the Superior Manufacturing Applied sciences programme of the Division of Science & Know-how (DST), the expertise works on a mix of Electrocoagulation and Electroflotation Enhanced Membrane Module (ECEFMM) methods for wastewater remedy, Science and Know-how Ministry mentioned in an announcement.

Whereas Electrocoagulation makes use of electrical cost for altering the particle floor cost, permitting suspended matter to type aggregates, Electroflotation separates suspended particles from water utilizing hydrogen and oxygen bubbles generated by passing electrical energy by way of water, the ministry famous. “Thus far, the separation expertise operating in several sectors for treating such oily wastewater entails the set up of an electrolytic cell or DAF adopted by membrane unit. Nevertheless, putting in two separate items requires a excessive footprint space in comparison with the current unit, the place two-unit operations are being assimilated in a single unit, mentioned Dr Bhattacharjee.

As a result of excessive price of present applied sciences, a considerable amount of untreated oily wastewater is discharged into the aquatic our bodies with out following the rules of the Air pollution Management Board. Nevertheless, the brand new expertise is possible by way of capital and recurring funding for low-scale and medium enterprises and has a “good market potential”. By integrating the “Electrochemical course of setup with the membrane module in a single hybrid ECEFMM setup, one course of has been eradicated. This considerably lowers the preliminary capital funding expense together with the extra benefit of decreased set up space requirement.”

Furthermore, the brand new expertise requires minimal manpower and doesn’t want high-end technical adequacy for its operation that cuts the operational expense to a big extent. The federal government mentioned that the recovered spent oil can be utilized as an industrial burner oil, furnace oil, mould oil, hydraulic oil, and so on., which might result in income technology scope for low-income teams.
