Introduction: What Is Moving Bed Kaldnes Biochip Technology?
Moving bed Kaldnes biochip technology is an advanced form of the Moving Bed Biofilm Reactor (MBBR) system. Developed in Norway during the late 1980s, this approach uses small, expertly designed plastic biochips that float freely in the reactor tank. These biochips support naturally occurring microorganisms that form biofilm layers. The result? Efficient biological treatment of wastewater in a compact, clog-free, and self-cleaning system
Why It’s a Game-Changer
📈 Maximized Biofilm Surface Area
The unique biochip design maximizes the protected surface area, enabling robust microorganism growth. With high internal surface area carriers, MBBR delivers exceptional treatment without clogging, even under heavy organic loads
🧠 Smart, Compact & Scalable
Because biochips float, the entire reactor volume is active—eliminating dead zones typical in traditional systems. Plus, it’s side-by-side upgradable: simply add more moving bed media to increase capacity

🔁 Efficient & Low‑Maintenance
With chaotic movement from aeration or mixing, dead biomass naturally detaches, keeping media clean without backwashing. This self-shedding behavior means stable, long-term operation and minimal maintenance
How It Works
-
Aeration/Mixing: A diffuser or mixer keeps biochips suspended.
-
Biofilm Growth: Beneficial microbes attach to the high‐surface‐area biochips.
-
Pollutant Removal: As water flows over the biofilms, organic pollutants are consumed.
-
Self‑Cleaning: Continuous movement sheds excess biofilm—keeping the system online
