Product Introduction
Biological rope packing (rope type biological packing) adopts a mixed weaving method of elastic and soft materials, and the wiring is made into braided tape packing using a snake like braided tape weaving method, forming countless circular fibers to form a radial structure, increasing its surface area and suitable for the growth and reproduction of various microorganisms. At the same time, it increases the porosity of the packing, enabling good transmission of solid, liquid, and gas phases; The circular structure can effectively prevent excessive peeling of biofilm caused by water flow impact.
