What Is MBBR Filter Media? The Essential Biofilm Carrier for Efficient Wastewater Treatment
MBBR filter media, short for Moving Bed Biofilm Reactor media, is a high-efficiency biological carrier used in modern wastewater treatment systems. It plays a vital role in promoting biofilm growth, enhancing pollutant removal, and optimizing biological treatment processes in both municipal and industrial applications.

What Material Is MBBR Filter Media Made Of?
MBBR media is primarily made of high-density polyethylene (HDPE) or polypropylene (PP). These materials are chosen for their:
- High mechanical strength
- Excellent chemical resistance
- Long-term durability in both aerobic and anaerobic environments
- Low density (less than water) for buoyancy and movement
In some special applications, modified polymer blends or virgin food-grade plastics may be used for enhanced biofilm adherence and longer service life.
Main Functions of MBBR Filter Media
MBBR media is designed to maximize the surface area for microbial growth within a treatment tank. Its key roles include:
- Carrier for Biofilm Formation
Microorganisms colonize the surface of the media, forming a stable biofilm that consumes organic pollutants (BOD, COD, NH₄⁺, etc.). - Enhanced Oxygen and Nutrient Exchange
The media continuously moves in the water (with aeration), allowing for efficient oxygen transfer and nutrient contact with the biofilm. - Increased Treatment Capacity
By increasing the effective biomass in the tank, MBBR media enhances removal rates without expanding tank size. - Low Sludge Production
The biofilm system produces less excess sludge compared to traditional activated sludge systems. - Stable and Resilient Operation
It adapts to load fluctuations and recovers quickly from system shocks or toxic inflows.
Where Is MBBR Media Used?
MBBR filter media is widely applied in both municipal and industrial wastewater treatment systems, including:
✅ Municipal Applications:
- Sewage treatment plants
- Decentralized domestic wastewater systems
- Retrofitting existing plants to improve capacity
✅ Industrial Wastewater Applications:
- Food and beverage processing
- Textile dyeing and printing
- Petrochemical wastewater
- Pharmaceutical industry
- Pulp and paper production
- Slaughterhouse and livestock wastewater
✅ Aquaculture:
- Recirculating aquaculture systems (RAS)
- Koi pond and fish tank bio-filtration
✅ Greywater & Septic Systems:
- Small-scale or modular domestic treatment systems
- Mobile toilets and containerized treatment units
Common Sizes & Design Recommendations
MBBR media comes in various shapes and dimensions, chosen based on the type of wastewater, loading rate, retention time, and tank design. Below are some common options:
| Media Type | Diameter (mm) | Surface Area (m²/m³) | Suitable For |
|---|---|---|---|
| K1-type | 25 × 10 mm | 500–600 | General municipal & light industrial use |
| K2-type | 36 × 18 mm | 400–450 | Higher loading, industrial wastewater |
| K3-type | 50 × 20 mm | 350–400 | Large tanks, rougher water |
| Mini-type | 10–16 mm | 800–1200 | Compact systems, aquaculture |
| Custom shapes | Varies | Up to 1200 | Designed for high-efficiency systems |
Design Tip:
- Filling rate: Typically 30–70% of tank volume depending on system type
- Retention time: 2–8 hours for BOD removal; longer for nitrification
- Aeration: Essential for proper media mixing and biofilm respiration
