Biofilm support for water purification and wastewater.

The invention relates A CARRIER ELEMENT FOR USE AS A CARRIER FOR MOVIE YET microbial purification process WATER OR BIOLOGICAL WASTEWATER IN WHICH ELEMENTS CARRIERS REMAIN IN MOTION IN WATER. The surface of the carrier is partially protected against collision with surfaces CARRIERS OTHER ELEMENTS. ELEMENT carrier has flow passages therethrough and is also designed to allow good water flow therethrough Also after a microbial film has imposed on surfaces. CARRIER ELEMENT has a length, width and / or height exceeding 1.5 cm, AND PROTECTED AREA GREATER THAN 10 M SUP {2} / M {SUP, 3} VOLUME ELEMENT CARRIER. THE CROSS OF openings SURFACE AREA AROUND THE LIMIT TO AT LEAST ONE element comprises 35% limit-SURFACE AREA OF A BODY homogeneous has the same dimensions. The invention also relates to the use of such elements CARRIERS FOR SEWAGE TREATMENT FROM INDUSTRY wood processing, waste water containing at least 100 mg / l suspended matter as measured on a filter-GF / A, AS WELL AS A REACTOR FOR THE CLEANSING OF WATER OR WASTEWATER BIOLOGICAL, comprising a tank reactor (20) containing BEARING ELEMENTS (25) according to the invention and where a net (26) covering the bottom of the tank is SUPPLIED ON aerators (21) into the fund.
