Ø     The environmental engineering laboratory is comprehensively equipped to conduct analyses of chemical and microbiological contaminants across various mediums, including air, water, wastewater, leachate, solid waste, and soil.

 

Ø     The laboratory houses advanced instrumentation, including High-Performance Liquid Chromatography (HPLC); Liquid Chromatography Time-of-Flight Mass Spectrometry (LC-MS); Gas Chromatography-Mass Spectrometry (GC-MS); Ion Chromatography (IC); Total Organic Carbon Analysers with Solid Sample Module (TOC-SSM); UV-Visible Spectrophotometers; Multi-Parameter Water Quality Meters; Respirable Suspended Particulate Matter (RSPM) Samplers; Indoor Air Quality Monitors (IAQ).

 

Ø     The laboratory is equipped with pilot-scale facilities for various processes, including pyrolysis, membrane bioreactors, sequencing batch reactors, membrane-aerated biofilm reactors, membrane filtration, and electrochemical reactors. This extensive array of equipment and facilities underscores our commitment to addressing environmental challenges through rigorous scientific inquiry and 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.
