K1 K3 PE05 PE08 HDPE MBBR Bio Filter Media for Wastewater and Aquaculture Treatment

MBBR Media is an advanced biofilm carrier designed for Moving Bed Biofilm Reactor (MBBR) systems used in modern wastewater treatment processes.
It provides a large and stable surface area for microorganism attachment, enhancing the biological degradation of organic matter, ammonia, and nutrients in both industrial and municipal water systems.
Within the MBBR reactor, these MBBR carriers freely move and mix with wastewater, maintaining optimal contact between biofilm, oxygen, and nutrients, resulting in highly efficient treatment performance.
MBBR Media is widely applied in MBBR water treatment systems for municipal, industrial, and aquaculture applications.

Feature

• High Specific Surface Area: Special internal structure design provides maximum surface area for biofilm growth, improving biological treatment efficiency.
• Lightweight and Floating: With a density around 0.96 g/cm³, the media remain suspended in water and resist sedimentation or clogging.
• Self-Cleaning and Non-Clogging: Continuous movement and surface shear prevent excessive biofilm accumulation, ensuring stable reactor operation.
• Durable and Non-Toxic Material: Manufactured from 100% virgin HDPE (High-Density Polyethylene), resistant to chemicals, aging, and UV exposure.
• Flexible to Load Variations: MBBR reactors automatically adapt to fluctuating inflow loads without operational adjustments.
• Low Energy and Space Saving: Compact reactor design reduces footprint and energy use compared to traditional activated sludge systems.

Application

MBBR Media is suitable for a wide range of moving bed bio reactor MBBR and MBBR water treatment systems, including:

• Municipal sewage treatment plants for BOD, COD, and nutrient removal.
• Industrial wastewater treatment — food & beverage, chemical, pulp & paper, textile, and pharmaceutical sectors.
• Decentralized and modular wastewater treatment units.
• Aquaculture and koi pond filtration systems (e.g., K1 Micro Kaldnes Filter for Koi Pond).
• River and lake remediation, ecological restoration, and polishing units.
• Ammonia and nitrogen removal, nitrification, and denitrification processes.

Package

• Standard Package: 0.1 m³ per woven bag, convenient for handling and installation.
• Bulk Package: 1 m³ jumbo bag for large-scale MBBR reactor projects.
• Transportation: Keep dry, avoid direct sunlight and heavy compression during transport and storage.
