METHOD FOR IMPARTING FILTERING CAPABILITY IN ELECTROLYTIC CELL FOR WASTEWATER TREATMENT

摘要

An electrolytic cell, system, and method for the energy efficient electrochemical treatment of wastewater comprising organic and/or inorganic pollutants are disclosed. The system comprises an electrolytic cell comprising a solid polymer, proton exchange membrane electrolyte operating without catholyte or other supporting electrolyte. The electrolytic cell also comprises a filter layer incorporated between the anode fluid delivery layer and the anode flow field plate for removing various contaminants including particulates and/or suspended solids from the wastewater stream. The cell design and operating conditions chosen provide for significantly greater operating efficiency.
