Treatment of Raw textile effluent using Hybrid Constructed Wetland
The integration of Vertical sub surface flow wetland (VSSF) and Horizontal sub surface flow wetland (HSSF) along with the incorporation of Canna indica was found to be very impactful in treating textile industry effluent as a significant removal percentage of Color, Turbidity, COD, and NH4N were observed. Validation experiments were conducted tomeasure DO, EC, pH, Turbidity, Color, COD and NH4N of both the source influent and the treated effluent. I particularly chose this topic because Bangladesh is one of the leading countries in the textile industry worldwide, numerous textile mills are located in its capital, Dhaka, generating large amounts of wastewater that require proper treatment. A hybrid constructed wetland is a technology that can be easily implemented in a country like Bangladesh as it requires comparatively small financial investment, and the operation and maintenance processes don't require much rigorous technical knowledge.

Heritage, Livelihoods and Delta Living: pasts, presents and alternative futures.
Participatory research to listen to and learn from a diverse group of younger and older people living in the delta regions to understand 1) Experiences of environmental change from the past to the recent times; 2) How people have responded to envrionmental change, individually and collectively; 3) How people have connected to their environment (livelihoods, history, leisure, culture); 4) People's hopes, concerns and ideas for the future. We are also trying to create Land Use and Land Cover (LULC) maps of this study area to see the shift of livelihoods along with the environmental changes that have taken place in this region in the past 30-40 years.
Methods: Oral History Interview, Participatory Resource Mapping, Participatory Photography etc.Softwares: ArcGIS, Google Earth Engine.
