Electro-assisted groundwater bioremediation: Fundamentals, challenges and future perspectives
2015
Li, Wen-Wei | Yu, Han-Qing
Bioremediation is envisaged as an important way to abate groundwater contamination, but the need for chemical addition and limited bioavailability of electron donors/acceptors or contaminants hamper its application. As a promising means to enhance such processes, electrochemical system has drawn considerable attention, as it offers distinct advantages in terms of environmental benignity, controllability and treatment efficiency. Meanwhile, there are also potential risks and considerable engineering challenges for its practical application. This review provides a first comprehensive introduction of this emerging technology, discusses its potential applications and current challenges, identifies the knowledge gaps, and outlooks the future opportunities to bring it to field application. The need for a better understanding on the microbiology under electrochemical stimulation and the future requirements on process monitoring, modeling and evaluation protocols and field investigations are highlighted.
