Major challenges in water and waste-water treatment include: Nutrient removal from waste-water; safe utilization of treated waste-water and digested biosolids; slow digestion of wastewater biosolids; protozoan cysts control in drinking water treatment; and absence of affordable disinfection methods in underprivileged countries. This research program will employ electrochemistry-based emerging technologies to provide solutions to these challenges. Bioelectrochemical systems with ion exchange membranes will be investigated for energy-efficient separation of nutrients and heavy metals from wastewater. Robust biosolids digestion is proposed by incorporating bioelectrochemical systems in conventional anaerobic digesters. Electrode reactions with copper and silver will be studied for effective and inexpensive drinking water disinfection.

水和废水处理方面的主要挑战包括：从废水中去除营养物;安全利用经处理的废水和消化的生物固体;废水生物固体的缓慢消化;饮用水处理中的原生动物包囊控制;以及贫困国家缺乏负担得起的消毒方法。该研究计划将采用基于电化学的新兴技术，为这些挑战提供解决方案。将研究具有离子交换膜的生物电化学系统，用于从废水中高效节能地分离营养物和重金属。稳健的生物固体消化提出了将生物电化学系统在传统的厌氧消化器。将研究与铜和银的电极反应以用于有效且廉价的饮用水消毒。
