Non-thermal plasma (NTP) technology offers a promising approach for pollutant abatement, gas conversion, and plasma-assisted combustion (PAC) by enabling reactions under atmospheric conditions, bypassing thermodynamic ... -
Evaluation of Btex Contamination in Bengaluru Groundwater and Remediation of Contaminated Water Samples
BTEX (benzene, toluene, ethylbenzene, and xylene isomers) are monoaromatic, volatile organic compounds (VOCs) with single benzene ring and various degree of alkylation. US EPA classifies benzene and TEX (toluene, ethylbenzene, ... -
Evaluation of the Engineering Properties of Municipal Solid Waste for Landfill Design
(2018-07-18)The objective of this thesis is to evaluate the engineering properties of Municipal Solid Waste (MSW) that are necessary in the design of landfills. The engineering properties of MSW such as compressibility, shear strength, ... -
Examining Climatic Response, Vulnerability and Adaptation in Rural Indian Dwellings to Climate Change: Case studies in three climatic zones
Buildings have evolved traditionally based on local resources and skills. They predominantly relied on passive climate-response mechanisms to provide indoor comfort. However, contemporary buildings, made primarily of bricks, ... -

(2017-09-26)The thesis, through experimental and numerical investigations reports on the work related to packed bed reactors in co-current configuration for biomass gasification. This study has extensively focused on the gasification ... -
Expermental and Modeling Studies on the Generation of Hydrogen Rich Syngas through Oxy-Steam Gasification of Biomass
(2018-02-20)The present work focuses on the study of biomass gasification process for generating hydrogen rich synthetic gas with oxy-steam as reactants using experiments and modeling studies. Utilization of the syngas as a fuel in ... -
Exploring End-of-Life Photovoltaic (PV) Panel as a Building Material: A Case of Crystalline Silicon PV
The renewable energy share in the energy mix worldwide is rising sharply to mitigate climate change, with Solar Photovoltaics (PV) carrying a large share of 3.6%. However, the end-of-life (EoL) management of decommissioned ... -
Fate and Remediation of Ammonium-n In Pit Toilet Blackwater
Pit toilets satisfy the sanitation requirement in regions with no access to piped sewerage facilities. Black water discharged from pit toilets is a major source of groundwater pollution. The primary focus of the thesis is ... -
Foaming of Surface Waterbodies: A Comprehensive Study on Causes, Persistence, Seasonality, and Mitigation Strategies
Foaming waterbodies have emerged as a significant global concern due to their adverse effects on aquatic ecosystems, offensive odour emissions, disruption of daily activities in nearby areas, and visual unpleasantness. ... -
Granular Media Supported Microbial Remediation of Nitrate Contaminated Drinking Water
(2018-01-11)Increasing nitrate concentration in ground water from improper disposal of sewage and excessive use of fertilizers is deleterious to human health as ingestion of nitrate contaminated water can cause methaemoglobinemia in ... -
Harnessing Packed-bed Biofilm Reactors for High-rate Saline Nitrification: An Innovative Application for Intensive Recirculating Aquaculture Systems
Saline effluents containing ammonia are generated by various human activities, including aquaculture, food processing, chemical industries, landfilling, etc. necessitating treatment to mitigate environmental harm. The ... -
