Sukalyan Sengupta, PhD

Factors influencing the physical, chemical, and biological characteristics of surface and ground waters. Unit operations and processes related to water treatment are emphasized.

The nature and causes of wastewater pollutants and the biological, chemical, and physical characteristics of these wastes. The analysis, treatment, and disposal of domestic, municipal, and industrial wastes are studied. Design of wastewater collection, pumping, and treatment facilities are practiced.

General topics of interest and relevance to civil & environmental engineering applications. Topics may include subject matter related to transportation engineering, geotechnical engineering, structures design, water resources, fluid mechanics, and/or environmental science and engineering. Laboratory and field exercises may supplement lecture material. Course can be repeated with change of content.

Chemical principles and applications of those principles to the analysis and understanding of aqueous environmental chemistry in natural waters and wastewaters. The chemistry of ionic equilibria, redox reactions, precipitation/dissolution, acid-base concepts, buffer capacity, complexation, hydrolysis and biological reactions. Applying basic principles of aqueous chemistry for quantifying complex, environmental systems. Specific examples of air-water-soil interactions and consequent effects. Heterogeneous equilibria with more than one solid phase. Kinetics and thermodynamics of some important ionic and biological reactions. Laboratory experiments.

Theory and application of adsorption, ion exchange, reverse osmosis, air stripping and chemical oxidation in water and wastewater treatment. Modeling engineered treatment processes.

Thesis research on an experimental or theoretical project in civil and environmental engineering under a faculty advisor. A formal thesis must be submitted to fulfill the course requirements.

Project research in conjunction with industry or government under a faculty advisor. A formal report must be submitted to fulfill the course requirements.
