Resumo(s)
Leachates produced from treatment plants contains carbon, nitrogen, phosphorus, potassium and trace elements. This work aims to develop heavy metals removal processes using solid adsorbents synthetized at CIMO and LSRE-LCM laboratories at Polytechnic Institute of Bragança, such as activated carbon produced from a compost material from the same treatment plant and modified clays obtained through a partnership with a Kazakhstan institution, to adequate the leachate from the composting line of a mechanical and biological treatment facility, into commercial fertilizers which fit the requirements of the European Legislation. Preliminary results show that the adsoption materials promoted a reduction in the heavy metals content, but this reduction also affected the organic carbon content. However, the activated carbons presented a better potencial for heavy metals removal.
