Arslan Ahmad is an internationally oriented water professional and a leading Research Scientist at KWR Watercycle Research Institute, with particular focus on the removal of (trace) metals and related substances from drinking water and aqueous waste streams, using a wide spectrum of treatment process such as chemical precipitation, fixed bed adsorption, ion exchange and membrane based techniques. Arslan is a key researcher in the Netherlands in the area of low arsenic and chromate concentrations in public drinking water supplies. Arslan is also focused on resource recovery from water, wastewater and residuals generated from the water treatment processes. He is experienced in up-scaling and piloting of technologies such as Eutectic Freeze Crystallization (EFC), Advanced Oxidation Coagulation Filtration (AOCF) and iron oxide based fixed-bed sorption. Arslan was the Exhibition Chair and Member of the Scientific Committee of 6th International Congress on Arsenic in the Environment (As2016). Arslan is Guest Editor of CRC Press/Taylor & Francis Book Series ‘Sustainable Water Developments’. Amongst his other international associations, KTH-International Groundwater Arsenic Research Group (KTH-GARG) and the International Society of Groundwater for Sustainable Development (ISGSD) can be highlighted here. After completing his BSc in Civil Engineering, Arslan Ahmad gained his MSc degree in & Environmental Engineering from the prestigious Royal Institute of Technology, Stockholm, Sweden. Prior to joining KWR Watercycle Research Institute Arslan worked in the Process Technology Department of Brabant Water, one of the public water companies in the Netherlands.
