DOI: 10.1016/j.jwpe.2021.102002
Abstract: Abstract The impacts of influent COD/N ratios on the floc properties and microbial communities of nitrifying sludge under high-strength ammonia conditions were investigated. Excessive organic loads severely deteriorated the nitrification rate and biomass-liquid separation. Moreover,… read more here.

Abstract: The characteristics of N2O emissions from an anaerobic/aerobic/anoxic (A/O/A) sequencing biofilm batch reactor (SBBR) were investigated under different influent COD/nitrogen (C/N) ratios (from 1–4). Results indicated that the C/N ratios affected the quantity of polyhydroxybutyrate… read more here.
