3D Elastic Biofilm Media - For Anaerobic, Aerobic & Anoxic Wastewater Treatment

Three-Dimensional Elastic Biofilm Media for Wastewater Treatment – Applicable in Anaerobic, Aerobic & Anoxic Tanks

The three-dimensional elastic filler is manufactured from premium polyolefins and polyamide, offering a unique balance of rigidity and flexibility. Its filaments are arranged in an optimized three-dimensional radiating pattern, enabling uniform distribution throughout the tank. This structure allows thorough mixing and exchange among air, water, and biofilm.

The biofilm attaches evenly to every filament, maintaining high microbial activity and adaptability. It provides a large specific surface area for effective metabolic activity, ensuring efficient organic degradation. This filler offers rapid biofilm formation, easy biofilm shedding, excellent growth and renewal of biomass, high resistance to impact loads, and a high CODcr removal rate. It delivers outstanding treatment performance and enhances oxygenation through multi-level collision and intensive cutting of bubbles, significantly improving oxygen utilization efficiency.

Key oxygen transfer parameters—such as overall oxygen transfer coefficient, oxygenation capacity, and oxygenation efficiency—exceed those of other conventional fillers used in China, resulting in reduced power consumption. Its innovative design offers a high surface area, prevents clogging and agglomeration, and ensures a long service life with potential for reuse. It is easy to manage in operation and demonstrates strong adaptability, making it suitable for treating various wastewater types, including low-concentration domestic sewage, medium-concentration printing and dyeing wastewater, papermaking wastewater, oily wastewater, and high-concentration food industrial and chemical wastewater. It is widely used in aerobic, anoxic, and anaerobic treatment processes.

Main Features

• Advanced Material Composition:
  Manufactured from selected polyolefins and polyamides with additives for hydrophilicity, adsorption, and thermal-oxygen resistance. Resists corrosion, temperature, and aging.

• Unique Structural Design:
  The filaments are three-dimensionally arranged and fixed to a corrosion-resistant central rope using specialized drawing and assembly techniques. The textured surface of filaments enhances microbial attachment.

• Optimized Performance:
  The filler combines appropriate stiffness and flexibility to maintain an ideal spatial distribution, allowing full contact among air, water, and biofilm.

• Enhanced Mass Transfer & Treatment Efficiency:
  Provides large specific surface area, excellent mass transfer, and renewability, contributing to stable and efficient biodegradation.

• Durable & Easy to Use:
  Long service life, reusable, simple to install and manage, suitable for a wide range of wastewater applications.
