Treatment and recovery of sulphur from polluted waters and gases provides new eco-friendly raw materials and remediated water streams. Thus a nuisance becomes a source of new and usable materials.

Sulphide is a highly toxic, malodorous and corrosive pollutant of waste-waters and -gases. Increasing concerns arise regarding the treatment of such wastewaters and gases due to the severe impacts they have on human and animal health, corrosion and odor problems. In the era of economical crisis and declining resources, materials should be recovered and reused. This complies with the general trend of growing environmental concerns and awareness, whereas discharge limits become more stringent worldwide. Thus, sulphur recovery from wastewaters and off-gas could provide a new eco-friendly raw materials, whereas at the same time, waste streams will be treated. Our electrochemical approach does not only remove corrosion, malodour and toxicity, but also recovers and generates two valuable products; sulphur and caustic soda.

Sulphide streams are treated and thus, corrosion, malodour and toxicity are removed. New valuable by-products are generated, which are an add-on value of the suggested process; they can be reused in-situ or sold as a new product. A nuisance becomes a source of new materials.
