Packing for a biofilm reactor with a movable layer

Packing for a biofilm reactor with a movable layer

A mobile layer biofilm reactor is a type of wastewater treatment process that was first invented by Professor Holvard Odegard at the Norwegian University of science and technology in the late 1980s. It was commercialised by the company Kaldnes Miljöteknologi. The system contains an aeration tank (similar to an activated sludge storage tank) with special plastic nozzles that provide a surface for film growth. The packings are made of a material that has a density similar to that of water (1 g / cm3). For example, high-density polyethylene (HDPE), whose density 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 packing.
