nitryfikacja - Opis:
- Complete nitrogen removal over nitrite (CANON) was used to treat reject water with ammonia concentrations ranging from 70 to 154mg·L-1. Two experimental sequential batch reactors, SBR_A and SBR_B, differed in the time of the reject water inflow (6h40min vs 40min), process temperature (25 vs 29°C), and the number of aeration periods per day (3 vs 6, respectively). Nitrogen removal efficiency was higher in SBR_B (50-90%) than in SBR_A (40-80%). Analysis of total (PCR-DGGE) and active (RT-PCR-DGGE) bacteria revealed that the biodiversity of the bacterial biocenoses, expressed as the Shannon-Wiener Biodiversity Index, was higher in SBR_B (2.75-3.10) than in SBR_A (1.80-2.75).
