Yes, we are a direct manufacturer with over 10 years of experience in MBBR bio media production. Our factory is equipped with multiple automatic production lines, strict quality control systems, and large-scale stock capacity, ensuring stable product quality, short lead times, and competitive factory prices for global customers.

Choosing the right MBBR media mainly depends on your project type (sewage treatment, aquaculture RAS, river remediation), treatment volume, water quality index, and required specific surface area.Common models include K1, K3, K5, MBBR 1912, 2510, etc. For domestic sewage, we usually recommend K3 or 25*10 media; for aquaculture RAS systems, high-specific-surface-area MBBR carriers are more suitable.You can send us your project parameters, and our engineers will provide a professional recommendation for free.

The main differences lie in size, specific surface area, filling rate, and application scenarios.K1 is small, low-cost, suitable for small sewage treatment equipment;K3 has moderate size and high biofilm attachment capacity, the most widely used for municipal and domestic wastewater;K5 is larger with higher specific surface area, mainly used for industrial wastewater and large-scale WWTP projects.All our MBBR carrier elements are made of high-quality HDPE, with strong toughness and long service life.

Our MBBR filter media has a service life of up to 8–15 years under normal use conditions.It does not need frequent replacement because the biofilm falls off and renews automatically during operation.Only under extreme conditions such as high temperature, strong acid, strong alkali, or physical damage may partial replacement be required. Regular aeration and proper operation can greatly extend its service life.

Yes, our MBBR bio media is specially designed for both wastewater treatment and recirculating aquaculture systems (RAS).It features non-toxic food-grade material, high specific surface area, fast biofilm formation, and excellent ammonia nitrogen and nitrite removal efficiency, which can effectively purify water, reduce fish mortality, and lower breeding costs.We have many successful RAS project cases in seafood farms and fish ponds worldwide.
