The research is focused on the production and optimization of biobased phenol formaldehyde foams for various applications for hydroponic seed germination in a greenhouse, and for environmental remediations (such as for oil-water separation, phosphorus recovery, and dye/heavy metals removal from wastewaters)

 Biomass pre-treatment methods such as de-polymerization reactions must be carried out using pilot-scale autoclave reactors (16 L)

The biomass used for the resin production includes various types of lignin (kraft, organosolv, lignosulfonate) and other agricultural residues

The synthesized bio-foams have to be analyzed using various characterization techniques such as SEM, Universal testing machine for strength applications

This work focused on investigating the hydrodynamic parameters in a bubble column reactor and devising a suitable scale-up mechanism which could be applied to various industrial processes like Fischer-Tropsch synthesis and wastewater treatment plants.

Experimental investigations were carried out in a pilot bubble column reactor (Height and Diameter = 2.5 m and 0.15 m) – Hydrodynamic parameters like gas holdups, dynamic gas disengagement and bubble behavior were analyzed

Computational and numerical investigations were carried out using Ansys package. 

The effect of vertical tube internals and dense tube bundles on the reactor hydrodynamics and turbulence parameters were experimented and validated using computational simulations.

The work dealt with biodegradation of polythene wastes when subjected to a novel consortium of Aspergillus spp. 

A novel bioreactor was designed and developed (for commercial use) which could effectively degrade polythene in the presence of fungal consortium of Aspergillus spp.
