Abstract

Trickling system for the purification of civic, industrial and agricultural waste-waters is equipped with trickling bodies that consist of fabric sheets made of synthetic filament yarns and/or synthetic staple fibre yarns. Has low water absorption, good resistance to rotting and to continuous trickling of heavily loaded waste-water, is easily cleaned and is of low cost. The yarns pref. consist of polyester, polyamide, polyacrylonitrile, polyethylene or polypropylene fibres. The fabric sheets may be uncoated or coated with plastic or rubber matl.
