Simultaneous treatment of gaseous BTEX and wastewater containing nitrate and sulphate by using an anaerobic hybrid bioreactor for methane production

Dr. Susant Kumar Padhi, Assistant Professor, Department of Civil Engineering received SRG grant (SRG/2020/002455) from SERB-DST, Government of India. He has been awarded the grant of ~ ₹ 20 Lakhs for duration of two years (2020-2022) with a project entitled “Simultaneous treatment of gaseous BTEX and wastewater containing nitrate and sulphate by using an anaerobic hybrid bioreactor for methane production”.

Summary of project:

The compound benzene, toluene, ethylbenzene, and xylene (BTEX) are highly volatile, majorly emitted from chemical, petrochemical, and paint-manufacturing industries found in liquid and gaseous form in the environment, causes a significant threat owing to their toxic and carcinogenic properties. This project aims to develop an anaerobic hybrid bioreactor (AHB) for the efficient removal of BTEX along with nutrients found in wastewater released from the industry. The broad objective of the project involves the design, installation, and process optimization of lab-scale AHB for the removal of BTEX from waste air and nutrients from wastewater simultaneously for the production of methane.
