  • Process for the purification of waste water
    Patent number: 5407576
    Abstract: In a process for removing organic impurities and heavy metals from industrial, commercial or communal waste water, loaded drinking water, refuse dump drainage water or aqueous special wastes, the wet pyrolysis residues produced during the extraction of usable gas in the pyrolytic processing of refuse are introduced into one or more aerated filter basins (17) or filtration reactors (26) connected in parallel or in series. The waste water, loaded drinking water, refuse dump drainage water or liquid special wastes to be filtered or purified are pumped through the pyrolysis residue until its capacity for physical adsorption is exhausted.
