Abstract [en]

The purpose of this study was to evaluate different types of metal decontamination from waste water. Specifically, to evaluate water from the mire located at Slagnäs railway depot. Through a literature review from Swedish authorities and entrepreneurs regarding water remediation methods have been compiled and compared. Methods for waste water remediation are chemical methods, sedimentation and filtration. Standardized methods for decontamination are constantly updated with new materials and improved methods. Neither one of these methods are relevant on their own. The idea behind the experiment was to use Fenton reaction on the mire water which would contribute to precipitation of metals. Within the study an experiment with hydrogen peroxide and sodium hydroxide was performed. The idea behind the experiment was to use Fenton reaction on the mire water which would contribute to precipitation of metals. No conclusions can be drawn about hydrogen peroxide also known as Fentons reaction due to lack of analysis results. Trials with sodium hydroxide shown that the best results occur when pH is moderately adjusted at pH 6 and 7. Due to incomplete analytical results no conclusion about Fenton reaction as a waste water treatment method can be drawn based on this experiment. The lack of results is probably due to the continuous reaction between Fentons and organic matter.
