Abstract
The invention provides an adsorbent suitable for column packing which is composed of a granular material obtained by subjecting a mixture of an activated sludge-containing material and a primary condensate of a formaldehyde type resin and/or a dialdehyde compound to heat-curing and granulating. The adsorbent can advantageously be used to treat industrial waste water containing ionic or nonionic water pollutants such as heavy metal ions, dyes, surfactants, high molecular weight coagulants and mineral oils.
