Sahar Dalahmeh
I am a researcher interested in wastewater treatment and reuse in agriculture as well as treatment of wastewater using filters of organic materials (biochar).

Presentation

My current research projects tackle the following 

- Minimization of wastewater pollutants including nitrogen, phsophorus and micro-organicns in samll scale wastewater systems using biochar filters, 

- Upstream activities to minimize micro-pollutants in wastewater

- Assessing uptake of micro-pollutants in plants and accumulation in soil in wastewater irrigated agriculture in low and middle income countries,
