Research Projects

Title of the Project: Study of Hydrodynamics and RTD of Effluent Treatment Process (Biological) Using "Radiotracer Technique".

Funding Agency: Department of Atomic Energy- Board of research in Nuclear Sciences(DAE-BRNS), Govt. Of India.

Collaborating Agency: Radiotracer Application Section, IP & RD, BARC, Mumbai

Collaborating Industry: Shreyans Paper Ltd., Ahmedgarh

Amount of Funding: Rs 24,51,650/-

Project Duration: 2015-2018 (3 Years)

Summary: RTD study using I-131 as radiotracer was successfully conducted to study the hydraulic behaviour of the complex Activated Sludge Process (ASP) at Shreyans Industries, Ahmedgarh, India. A set of experiments were performed to characterize the flow behavior of aeration tank, secondary clarifier and complete ASP. The investigation revealed there were no flow abnormalities such as bypassing and parallel flow paths inside the aeration tank. The dead volume inside the aeration tank was negligibly small. Therefore, the aeration tank operates at its designed hydraulic efficiency. In the secondary clarifier was also found to be operating normally without and significant malfunctioning. Suitable hydrodynamic models were suggested for the system to provide physical representation of the system’s hydraulic behavior. The modelling of the measured RTD of the wastewater in the aeration tank revealed that the hydraulic behavior of the aeration tank could be represented by two CSTRs with moderate degree of the back mixing between them. The secondary clarifier behaved a plug flow reactor and was represented by axial dispersion model. Based on the priori information and results of the modelling of the individual systems, a model was proposed for the entire activated sludge processing system.
