In　the　manufacturing　industry,　chromium　is　often　discharged　with　the　effluent,　which　releases　significant　contamination　to　the　environment.　To　remove　chromium　from　wastewater,　many　different　treatment　techniques　have　been　developed.　The　present　work　reports　the　treatment　of　chromium　pollution　using　electrochemical-based　remediation　strategies,　including　electrodeionization,　electrodialysis,　electrochemical　reduction,　and　electrocoagulation.　This　work　also　presents　the　principles　and　mechanisms　of　these　strategies,　along　with　research　trends　into　the　electrochemical　removal　of　chromium.　©　2018　The　Authors.
