MBBR
The mobile bed biofilm reactor is a type of wastewater treatment process that was first invented by Professor Holvard Odegaard at the Norwegian University of Science and Technology in the late 1980s. It was commercialized by the company Kaldnes Miljöteknologi. The system contains an aeration tank (similar to a activated sludge storage tank) with special plastic nozzles that provide a surface for film growth. The nozzles are made of a material that has a density similar to that of water (1 g / cm3). For example, high-density polyethylene (HDPE), the density of which is 0.95 g / cm3. The packing is mixed in the tank by an aeration system, which improves the contact between the substance of the contaminated waste water and the biomass on the nozzle.
