Electrocoagulation is progressively becoming an ecologically friendly water treatment method owing to its lack of secondary pollution

high active ingredient concentration

high treatment effectiveness

simple equipment

and simplicity of automated control implementation. Herein

electrocoagulation is offered as a method for treating wastewater containing azo dyes using a revolutionary flexible electronic fabric that can be mass-producible at a reasonable price. A computer-controlled machine embroiders 316L stainless steel fiber (316L SSF) onto an insulating fabric to manufacture a flexible electronic device of cathode and anode with a monopolar arrangement on the fabric surface. Using methyl orange (MO) solution to simulate azo dye wastewater

the decolorization rate of 500 ml MO reached 99.25% under the conditions of 50 mg·L
