innovation
a)
Environmental Engineering
Lab:
This laboratory serves
as the primary facility for all practical classes for both undergraduate (UG)
and postgraduate (PG) programs. The undergraduate curriculum encompasses
fundamental analyses of water and wastewater, in addition to monitoring and
evaluating indoor and outdoor air quality. The lab
focuses on various aspects of water and wastewater pollution, employing
advanced instruments for testing chemical, biological, and physical parameters
like pH, turbidity, dissolved oxygen, and heavy metals. It also monitors indoor
and outdoor air quality, utilizing air sampling and analysis tools to detect
pollutants such as particulate matter, volatile organic compounds, and gases
like CO2 and NOx. In addition, the lab supports solid waste management research
by testing waste composition, recycling methods, and waste-to-energy
technologies. Microbiological analysis is conducted to study pathogens and
microbial contamination in water, wastewater, and soil samples.
b)
Microbiology and
Ecotoxicology Lab:
A Microbiology and
Ecotoxicology Laboratory focuses on studying microorganisms and their
interactions with the environment, particularly in relation to pollutants and
toxins. In microbiology, the lab investigates microbial diversity, behaviour,
and their role in environmental processes. Ecotoxicology examines the impact of
chemical substances, such as pesticides, heavy metals, and pharmaceuticals, on
ecosystems, particularly how pollutants affect microbial communities, plants,
and animals. This research is crucial for understanding ecosystem health,
biodiversity, and sustainability.
c)
Pilot Scale Laboratory:
A Pilot-Scale Testing Laboratory is
equipped with advanced facilities to test and optimize various industrial
processes before full-scale implementation. This lab is crucial for evaluating
technologies in real-world conditions, ensuring scalability and efficiency. It
houses pilot-scale units for pyrolysis, where organic materials are thermally
decomposed in the absence of oxygen, producing valuable products like bio-oil
and syngas. The lab also supports membrane bioreactors (MBRs), which combine
biological treatment with membrane filtration to treat wastewater efficiently.
Sequencing batch reactors (SBRs) are utilized for flexible, batch-based
wastewater treatment, while membrane-aerated biofilm reactors (MABRs) enhance
microbial activity and nutrient removal in wastewater systems.
