Treating prepurified water containing difficult to degrade components, e.g. drug metabolites, comprises contacting with biologically regenerated adsorbent with simultaneous physical and biological action

摘要

Treatment of biologically prepurified water, containing difficult to degrade components, comprises contacting with a biologically regenerated adsorbent. An independent claim is included for corresponding apparatus, consisting of at least one hollow disk filled with adsorbent, which rotates in a trough containing waste water in the form of a disk immersion dripping body.
