Bio Media Filter MBBR Carrier

MBBR 37 Bio Media Filter Carrier | High-Density Biofilm Carrier for Industrial Wastewater Treatment

Built for the Harshest Loads. Engineered to Outlast.

The MBBR 37 bio media filter carrier is Juntai's answer to high-TDS industrial effluent, chemical-laden wastewater, and unpredictable shock loads - where standard carriers simply fail.

When municipal-grade media isn't enough, engineers turn to the MBBR 37. Designed specifically for industrial wastewater environments - including chemical processing, pharmaceuticals, and high-salinity effluent streams - this 37-hole carrier sustains biological activity under conditions that cause conventional media to lose performance within weeks.

Manufactured from 100% virgin HDPE at Juntai's ISO-certified facility in Hangzhou, China, each MBBR 37 carrier is precision-extruded to deliver a protected internal surface area optimized for slow-growing nitrifiers and resilient heterotrophic bacteria alike. The result is consistent COD and ammonia removal, even when your influent isn't.

Technical Specifications

Why the 19 or 37 Hole Design Matters

Standard MBBR carriers use 4, 5, or 6 internal channels. The MBBR 37 takes this further - 37 precisely engineered channels create a dramatically higher ratio of protected internal surface to outer envelope.

1. Shear Protection

In aerated reactors, turbulence strips biofilm from exposed outer surfaces. The MBBR 37's deep internal channels shelter nitrifying bacteria - the slowest-growing and most sensitive organisms in your system - from hydraulic shear. Colonies survive and thrive where they'd otherwise wash out.

2. Oxygen Gradient Zones

The 37-hole geometry naturally creates both aerobic outer zones and micro-anoxic inner zones within a single carrier. This enables simultaneous nitrification and denitrification (SND) in a single-tank configuration, reducing reactor footprint and capital cost.

3. Self-Cleaning Under Motion

As the carrier tumbles in the moving bed, inter-channel turbulence continuously sloughs excess biofilm from the inner walls, preventing clogging and maintaining consistent mass transfer - no backwashing, no manual intervention required.

Industry Applications

Chemical & Petrochemical

High TDS, variable COD, and pH swings are no match for the MBBR 37. Maintains 95%+ treatment stability at TDS levels up to 15,000 ppm, with consistent performance across batch production cycles.

Pharmaceutical

Recalcitrant organics and slow-growing degraders require protected micro-environments. The MBBR 37's internal channel geometry shields specialized microbial communities from hydraulic disruption, sustaining API removal rates even under variable influent quality.

Food & Beverage

Handles high BOD/COD loads and temperature fluctuations common in dairy, brewery, and food processing effluent. Biofilm re-establishes rapidly after shock loads, ensuring continuous discharge compliance.

Textile & Dyeing

Compatible with hybrid MBR-MBBR configurations for azo dye and formaldehyde removal. Achieves 80%+ color removal in space-constrained dye houses without extensive civil works.

Municipal WWTP Upgrade

For plants facing tightening discharge standards or capacity constraints, the MBBR 37 delivers 2–3× throughput increase in existing aeration tanks - no new civil expansion required.

The Juntai MBBR 37 Advantage

Anti-Corrosion HDPE Construction

Virgin HDPE formulation withstands acids, alkalis, and organic solvents common in industrial effluent. No degradation, no leaching, no structural loss over a 15+ year service life.

Consistent Manufacturing Tolerances

Every batch is produced on precision extrusion lines with in-line QC, ensuring dimensional uniformity across millions of pieces. Consistent geometry means consistent hydraulics - and consistent treatment performance.

Factory-Direct Supply

As the manufacturer - not a trading company - Juntai supplies MBBR 37 at competitive ex-factory prices with full batch traceability. MOQ and volume pricing available on request.

Engineering Support Included

Our technical team supports your project from specification to commissioning: fill ratio recommendations, aeration calculations, reactor sizing, and on-site guidance. We don't just ship media - we help you make it work.

Installation Guidelines

Fill Ratio: 50–67% of reactor volume (higher ratios reduce mixing efficiency)
Aeration: Coarse-bubble diffusers at 0.3–0.5 m³ air/m³·h; avoid fine-bubble systems directly below media
Retention Screen: Vertical bar screens or slot sieves (slot width: 8–10 mm)
Storage: Dry, shaded, ≤ 40°C; stack ≤ 2 m high; UV-resistant covering for outdoor storage

Frequently Asked Questions

How is the MBBR 37 different from K1/K3/K5 type media?

K-series carriers use a simpler fin geometry optimized for municipal applications. The MBBR 37's 37-hole cross-wall design provides greater internal surface area and superior protection for slow-growing organisms in high-load industrial environments.

Can MBBR 37 be used in retrofit / upgrade projects?

Yes. The carrier is compatible with both new MBBR reactors and IFAS upgrades to existing aeration tanks. Our engineers can assist with retrofit calculations at no additional cost.

What is the minimum order quantity?

Please contact us for MOQ and volume pricing. We supply both pilot-scale quantities for laboratory biofilm trials and full-project bulk orders.

Does Juntai provide samples?

Yes, sample packs are available for evaluation. Contact our team to arrange shipment.
