Abstract
A method for producing an iron-containing sorption material for treating feed water or waste water in order to remove harmful trace constituents by adsorption. To this end, an iron-containing solution is initially dehydrated in order to increase the salt content and transformed into a suspension of iron-containing solids from which the sorption material is obtained. By subsequently increasing the pressure of the suspension at a temperature of less than -5° C., the iron-containing solids in the suspension are transformed to dimensionally stable solid complexes. The iron-complex containing particles significantly facilitate treatment of water to remove hazardous trace materials because they provide a large surface area for carrying out the adsorption, yet filters made of this material do not become clogged even when treating heavily polluted waste water. In addition, the use of the sorption material of the invention makes it possible to dispense with use of fillers and/or auxiliary filter materials.
