dc.description.abstractThe treatment of leachates as pollutant concentrated wastewaters, is still an open issue, and althoughseveral different methods are applied for this goal, we are still far way from obtaining low-cost and at the sametime efficient processes. Even for wastewater and water, removal of specific contaminants is far from beingeconomical.Magnetic particles (nano or micron-sized), namely those based on iron oxides, have shown good sorptioncapabilities, which may be useful for removal/concentration of pollutants/nutrients. Joining this sorptioncapabilities with their magnetic properties, and with potential functionalization, makes the application of theseparticles for wastewater or leachate treatment very interesting, specially as we may use magnetic separationmethods to further remove, recover and reuse these particles.In this work we have tested three different kind of magnetic particles, in order to remove/concentrateorganic matter (DQO reduction), Nitrogen (Total Nitrogen) and Phosporous (Total Phosporous), during severaltime periods, being successful in removing between 4 and 65 % of them, depending on the controlledparameter, sorption time and type of particle.We have applied the same particles in three different water streams with different degrees of pollution,so we would be able to analyze the pollutant concentration influence: these being water, wastewater andleachate. In Figure 1 we present as example the case of removal for wastewater resultant from sludgecentrifugation, by one of the three different magnetic particle systems we have used.
