Sentence examples for nitrogen sewage from inspiring English sources

Modeling results show that AOA would outcompete AOB under low ammonium concentration and low dissolved oxygen conditions due to the revealed higher NH4+ affinity (KAOANH4 of 0.06 g N m−3) and thus higher ammonia oxidation rate under oxygen-limited conditions, indicating that AOA could be a better partner to Anammox bacteria compared to AOB when treating low strength nitrogen sewage.
