Improved method and device for treating waste

摘要

The present invention relates to a method and device for treating a waste stream comprising a liquid fase which is at least partially associated to solid materials. The method according to the invention comprises the steps of: (i) subjecting said waste to a size reducing treatment, (ii) separating the size reduced waste in a first fraction with an elevated metal content and a second fraction with a reduced metal content, (iii) subjecting the first fraction to a cold treatment thus forming a cold waste fraction, (iv) separating the cold waste fraction in a third fraction with an elevated metal content and a fourth fraction with a reduced metal content. The device according to the invention is useful for carrying out such method. <IMAGE> <IMAGE>
