RBC or Biodisc is a simple and reliable unit for reducing the BOD by biodegradation, and for nitrifying civil and industrial waste. They provide high efficiency performance in eliminating the polluting matters, for carbon removal and nitrification/denitrification processes. 

The use of biodiscs offers a remarkable saving of space, minimizing the environmental impact and simplifying plant management. Energy consumption is drastically reduced when compared to traditional processes.
