<p>The pyrolysis residue from pyrolytic treatment of waste materials with a content of organic material, which is discharged via a water bath, is used for the purificn. of industrial or urban effluent water, contaminated drinking water, ground water or aq. special wastes contg. organic contaminants and heavy metals, by means of filtration. The pyrolysis residue is held at at least 10% moisture content and introduced into one or more parallel or series connected, aerated filter vessels or filtration reactors and the effluent water etc. to be treated is pumped through the wet pyrolysis residues until their physical adsorption power is exhausted. Pref. silicate materials and clays such as zeolites, bentonite, montmorillonite, rodonite, etc., may be mixed with the waste material entering the carbonisation unit to improve the binding of organic material and heavy metals.</p> |
