Abstract [en]

A literature study was conducted, primarily using online databases and through contacts with organisations and contractors. The aim was to find technologies, applicable at Nexplo Bofors AB in Karlskoga, for cleaning explosives contaminated wastewater. The contaminants in focus were mainly TNT, RDX and HMX, separately or in combination, such as pink water. The methods found and presented in the report are diverted into separation and destruction technologies. Each method is described and data of efficiency and costs, in that extent these were found, are presented. The study was mainly focused on new innovative technologies, and not conventional methods such as granular activated carbon (GAC), which had already been investigated by Nexplo Bofors AB and judged as too expensive for them to use. It was problematic to draw conclusions of which method was the most suitable for Nexplo Bofors AB, due to lack of information or contradictions in the found information. Most of the cost data was incomparable between the methods since it was given in different units. Furthermore, the list of wastewater flows and its concentrations at Nexplo Bofors AB that was made for the literature survey was a bit unclear. Moreover, many of the methods found are not yet commercially available and therefor it was not possible to draw any conclusion without contacting the contractors. Due to lack of time this was not done for most of the methods. It could be noted that the installation cost seemed, after all, least for the activated carbon (GAC and PAC), even if Nexplo Bofors AB considered it to be too expensive. The Thermophilic Biological Process seemed economically potential, as well as Oxidation with UV/H2O2 and the CerOx process. The most expensive method seemed to be Wet Oxidation and Supercritical Water Oxidation, but in combination with a separation method the costs for these decreased. However, to get a clearer picture of the costs involved, deeper contact has to be made with the different contractors. To make a tailored design and a detailed cost estimation the contractors will probably charge Nexplo Borfors AB for this consultant service.
