The duplexWASTE project, coordinated by Institut de la Corrosion, will focus on investigating corrosion properties and limits of use of (lean) duplex stainless steel in the wastewater treatment field. It will then be needed to characterize the corrosiveness of investigated units. Corrosion data on application of duplex stainless steel in wastewater treatment units will be generated with both field and laboratory exposures. This includes the corrosion resistance of duplex stainless steel to halogens (chloride, …) and chemicals added for oxidation, flocculation and disinfection and formed by- and end-products including gaseous products present in surrounding atmosphere (e.g.; H2S). Speical attention will be paid to microbial induced corrosion risks (MIC).The experimental program is built in regards with the literature survey and the experience of the partners. It is believed that this effort will result in engineering diagram for proper material selection of duplex stainless steel for wastewater application and will largely increase the use of these materials.
