<p>This invention relates to a biofilm carrier (B) made of yarns comprising a central yarn (1) made of elementary fibres (4), where the individual elementary fibres (4) constituting the central yarn (1) constitute a continuous fibre running over the entire length of the yarn (1), and a loop (2) made of further yarns (1) is fixed to the central yarn (1) at least at two anchor points (3a, 3b) and, moreover, the arc length of the loop (2) between two adjacent anchor points (3a, 3b) is bigger than the length of the central yarn (1) between two adjacent anchor points (3a, 3b).</p> |
