In the design and operation of Moving Bed Biofilm Reactors (MBBR), the most critical question engineers ask is: "How many kilograms of Ammonia Nitrogen (NH_3-N) can 1 m³ of media remove per day?"
Understanding this value is the key to optimizing tank volume, reducing footprint, and ensuring stable effluent quality. At HINKTON, we define the gold standard for high-load nitrogen removal.
When clients ask for our specific performance data, our answer is backed by rigorous testing and field applications:
600 – 1250 gNH_3-N/m³ of carrier·d (Up to the Oxygen Transfer Limit)
This means that under optimal dissolved oxygen (DO) and nutrient conditions, HINKTON media can process up to 1.25 kg of ammonia per cubic meter every single day—pushing the biological process to its physical and chemical ceiling.
To understand the value of HINKTON engineering, we must look at how it compares to standard PE (Polyethylene) media often found in the market.
| Performance Metric | Standard Market Media | HINKTON High-Activity Media |
| Ammonia Loading Rate (NH_3-N) | 300 – 500 g/m³·d | 600 – 1250 g/m³·d |
| Active Surface Area | 500 – 800 m²/m³ | > 1000 m²/m³ (Select Models) |
| Biofilm Maturity Period | 20 – 30 Days | 7 – 14 Days |
| Material Composition | Recycled or Low-Grade PE | 100% Virgin HDPE with Hydrophilic Modifiers |
| Service Life | 5 – 8 Years | 10+ Years |
The secret to achieving 1250 g/g/m³·d lies in our specialized manufacturing process and material science:
Advanced Hydrophilic Modification: Unlike standard plastic carriers that repel water initially, HINKTON media is treated with special hydrophilic functional groups. This allows the biofilm to attach faster and stay thicker, significantly shortening the "start-up" period.
Optimized Fluid Dynamics: Our honeycomb and cylindrical structures are designed to ensure maximum water flow through the internal surface. This prevents "dead zones" and ensures that every square millimeter of the carrier is contributing to nitrification.
High Void Fraction: With a design that promotes high turbulence, our media maintains a thin, highly active biofilm. Old, inactive sludge is naturally sheared off, leaving only the most efficient nitrifying bacteria.
In a recent municipal wastewater upgrade, replacing generic media with HINKTON high-performance carriers allowed the plant to handle a 40% increase in ammonia influent without expanding the physical footprint of the aeration tanks. By operating at the oxygen transfer limit, the plant achieved consistent $NH_3-N$ effluent levels of $< 1$ mg/L, even during peak loading.
When you choose HINKTON, you aren't just buying plastic carriers; you are investing in high-rate biological efficiency. By reaching a removal rate of 600 – 1250 gNH_3-N/m³·d, we help you minimize costs, maximize space, and meet the strictest environmental regulations.
