<p>A bio-contactor for cleaning wastewater, where a system (1) of bio-discs (13) is divided into two unevenly sized parts (11, 12) located at both ends of an electrical transmission (5). The bio-discs (13) have the form of low cones or flat round caps. They are threaded onto a shaft (2) so that halfway down the individual sections (11, 12) of the system (1) there is a spacing collar (6). Around that the bio-discs are threaded symmetrically towards the spacing collar (6) by the base. The free ends of the bio-discs (13) are reciprocally joined by through tenons (52).<IMAGE></p> |
