Dr. Amro Hassanein

ahassane@umd.edu

Dr. Hassanein has experience in determining the effect of electrocoagulation on wastewater evaluating the anaerobic digestion performance on different types of bioplastic, improving biogas production of cassava wastewater using zeolite and biochar additives and manure co-digestion. He examined the impacts of biochar loaded with nickel and iron nanoparticles on hydrogen sulfide removal and investigated biogas enhancement and ammonia extraction to increase revenue in waste-to-energy systems.
