What is biological rope filler?

The biological rope filler (rope type biological filler) adopts a mixed weaving method of elastic material and soft material, and the wiring adopts a serpentine braid type weaving method to produce a braid type filler. The formed annular fibers form a radial structure, which increases its surface area and is suitable for the growth and reproduction of various microorganisms, enabling the concentration of attached microorganisms to reach over 15000 mg/L; The circumferential radial structure formed by elastic and soft materials increases the porosity of the filler, enabling good transmission of the solid, liquid, and gas phases; The annular structure can avoid excessive peeling of biofilm due to water flow impact.

The strength of the centerline directly affects the stable operation of the system. With the fixation of the biofilm, the weight of the filler will gradually increase, and under the impact of water flow, it is prone to wire breakage, central rope breakage, and other situations, affecting its service life. The rope type biological filler adopts a high elastic wire mixing process, and a single mixed braided wire can withstand a tensile force of 5kg. Due to the central rope fixation method of the rope type biological filler, a total of 12 mixed braided wires are used in a single section, and the measured biological rope filler can withstand a tensile force of 60kg.
