Disinfection byproduct (DBP) control in drinking water: carcinogenic DBPs are formed during drinking water chlorination/chloramination. This study will explore options for reducing the health risk associated with elevated DBPs levels in drinking water by (1) removing precursors in source water and (2) transforming the DBPs in finished water.
Treatment of waste streams from water/wastewater treatment process: some water/wastewater treatment processes produce waste streams with concentrated contaminants, such as ion exchange resin regeneration brine, membrane process retentate, saturated activated carbon, microbial reactor sludge, etc. Research in this area will evaluate the feasibility of innovative treatment approaches to recycle/regenerate valuable resources in these wastes, and abate the negative environmental effects for waste disposal/discharge.
Treatment of wastewater from the energy industry: research in this area will investigate the integration of physical, chemical and biological processes (e.g., adsorption, ion exchange, electrochemical and biological degradation) to remove a variety of inorganic and organic contaminants in wastewater generated in power plants and shale gas production processes, and explore the potential for treated wastewater reuse.
