Water and Health

水和废水处理方面的主要挑战包括：去除废水中的养分；安全利用经处理的废水和消化的生物固体；废水生物固体消化缓慢；饮用水处理中的原生动物包囊控制；贫穷国家缺乏负担得起的消毒方法。这项研究计划将利用基于电化学的新兴技术来为这些挑战提供解决方案。将研究离子交换膜生物电化学系统，以实现废水中营养物质和重金属的高效分离。通过在常规厌氧消化池中加入生物电化学系统，提出了一种稳健的生物固体消化方法。将研究与铜和银的电极反应，以实现高效、廉价的饮用水消毒。

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.
