DESCRIPTION:Most current methods of water and wastewater treatment systems 
 involve purchasing and transporting chemicals to centralized treatment fac
 ilities\, which entails the emission of greenhouse gases.  Interest in dec
 entralized treatment systems is growing\, partly because pumping water to 
 and from treatment facilities constitutes a significant fraction of the ov
 erall energy used within the water cycle.  Electrochemical treatment syste
 ms are particularly attractive for decentralized systems\, since they redu
 ce the need to transport reagents\, are modular in nature\, and can be ope
 rated remotely.  However\, while electrochemical treatment technologies ar
 e a potentially powerful tool for advancing decentralized treatment\, ther
 e are three main limitations that inhibit scale-up: (1) a focus on oxidati
 ve (anodic) systems\, (2) use of costly electrode materials\, and (3) inef
 ficiencies due to targeting microconstituents (< mg/L).\n\nThis seminar wi
 ll propose a paradigm shift that addresses these three challenges and enha
 nces process efficiency.  In this work\, I aim to transform current electr
 ochemical methods by: (1) developing cathodic\, reductive systems instead 
 of anodic\, oxidative systems\, (2) using low-cost\, commercially availabl
 e electrode materials\, and (3) targeting macroconstituents (> mg/L)\, whi
 ch outcompete microconstituents for reactions.  This seminar will cover th
 ree environmental applications for reductive electrochemical treatment sys
 tems\, including: potable reuse\, wastewater discharge\, and a potent gree
 nhouse gas used for agricultural fumigation.  Using real water or matrix c
 onditions\, I assess energy requirements and develop initial cost estimate
 s against currently used technologies to assess the feasibility and future
  research priorities of the electrochemical process.  These proof-of-conce
 pt electrochemical treatment technologies advance the field towards more e
 fficient systems that are practical for real-world implementation.
