ABSTRACT:
The present invention relates to a process for producing an adsorbent for the treatment of waste water, suitable for column packing, which is composed of a granular material obtained by subjecting an aqueous mixture of an activated sludge-containing material and the water-soluble primary condensate of a formaldehyde-type resin and/or an aldehyde compound to a curing treatment with an acid catalyst and a granulating operation. The adsorbent can advantageously be used in disposing of industrial waste water containing ionic or nonionic water pollutants such as heavy metal ions, dyes, surfactants, high molecular weight coagulants and mineral oils.
