The core of the MBBR technology are the biofilm carriers. They are designed to provide a large protected surface area for the biofilm and optimal conditions for the bacteria culturea when the carriers are suspended in water.

Small Boss has developed several types of carriers with different shape, size and surface area. This gives us the flexibility to use the best suitable carrier depending on wastewater characteristics, pretreatment, discharge standards and available volumes. Currently we have ten different types of carriers.
