Nitrification in hybrid reactor with a recycled plastic support material

This work investigated the nitrification in a hybrid moving bed pilot scale reactor, which used a low density recycled plastic support material for biomass growth. The filling rate was 20% of its working volume (22L). The feeding and recirculation outflow was 45L/day. The reactor operated at a tempe...
