MBBR bio media is a high-efficiency attached-growth carrier widely used in MBBR and integrated AO/MBBR wastewater treatment processes. Its surface is specially treated to provide a high specific surface area, promoting rapid biofilm formation and microbial metabolic activity. The media features a lightweight, hollow structure with excellent compressive strength and chemical stability, ensuring long-term stable operation under aeration and mixing conditions.
1️⃣High Specific Surface Area – Unique structural design accelerates biofilm growth and enhances microbial activity.
2️⃣Excellent Mobility – Hollow structure ensures uniform flow mixing, preventing dead zones and clogging.
3️⃣Durable Material – Made of HDPE (High-Density Polyethylene), resistant to acid/alkali corrosion, aging, and high temperatures.
4️⃣Self-Cleaning Ability – Continuous movement promotes natural sloughing of aged biofilm, reducing sludge accumulation.
5️⃣Flexible Filling Ratio – Adjustable media filling rate based on influent load and target effluent quality.
