Dr. Zubair Ahmed has been involved in several national and international environmental projects including implementation of cleaner production technologies in textile industries, techno-economic studies of wastewater treatment plants, environmental impact assessments and environmental audits of industrial units, pilot plant studies for domestic/industrial wastewater treatment using innovative processes such as sulfur based autotrophic denitrification &up-flow anaerobic sludge blanket process. Dr. Ahmed has more than 20 years of teaching, research, and consulting experience. His primary research interest is in biological wastewater treatment, particularly, in the application of membrane bioreactors for nutrient removal, bio fouling, microbial community structure in sludges, anaerobic digestion of waste, and the fate of emerging pollutants in MBRs. He has also worked on development of different adsorbents for water treatment. Currently, he is focusing on resource recovery from waste. His research output has been published in leading peer-reviewed journals.
