Biological Rope
Media

Biological rope (braided belt) media — a new-generation eco-friendly bio-active carrier made from lightweight, high-strength, corrosion-resistant chemical-fibre net yarn. Its spiral tube structure and millions of surface loops give a large surface area, fast biofilm formation and easy shedding, for aerobic, anaerobic and anoxic service.

Why this media

High surface,
fast biofilm

The looped, grass-like structure holds a large biofilm and cuts bubbles, while staying easy to install and clean.

Large surface, fast film

High surface area and porosity give fast biofilm start-up and easy, continuous shedding/regeneration.

Cuts bubbles

Effectively cuts air bubbles, raising oxygen transfer rate and utilization.

Water-grass form

Mimics natural water grass, resists sludge accumulation, needs no support frame, and has a long, impact-resistant service life with stable effluent.
