Sulphate-based electrochemical processes as an alternative for the remediation of a beauty salon effluent.

Beauty salons (BS) are places that deal with a wide range of cosmetics with potentially hazardous chemicals, and their effluent should be properly treated before going to the sewage system, once it represents characteristics of industrial wastewater. This work provides an extensive characterization of a BS effluent and its respective electrochemical treatment by comparing NaCl, NaSO, and NaSO as supporting electrolytes with a boron-doped diamond (BDD) as anode, applying 10 or 30 mA cm of current density (j). The inclusion of UVC irradiation was also performed but the improvements achieved in removing the organic matter were null or lower.
