Description

Technical Parameters

MBBR 04 Bio Media

Ultra-high surface area biofilm carrier
for compact & aquaculture systems

11×7 mm - the smallest carrier in Juntai's range. Over 900 m²/m³ specific surface area - 80% more biofilm surface than K1/K3 in the same reactor volume. Purpose-built for RAS biofilters, packaged treatment units, and high-rate nitrification where every cubic metre counts.

MBBR 04 bio media filter carrier

Key advantages

↑

80% more surface area

vs K1/K3 at equivalent fill ratio - same tank volume, far greater treatment capacity

🐟

RAS-optimised geometry

Short internal diffusion paths outperform larger carriers at low ammonia concentrations

⏱

Fast biofilm startup

5–14 days to full colonisation - quicker than K3 or MBBR 37 in identical conditions

🏗

No civil expansion needed

Replace existing carriers in-tank for instant capacity upgrade - no new construction
