Advanced nitrogen removal from municipal sewage via partial nitrification-anammox process under two typical operation modes and seasonal ambient temperatures

A two-stage partial nitritation-denitritation/anammox (PN-DN/A) process to treat high-solid anaerobic digestion (HSAD) reject water: Verification based on pilot-scale and full-scale projects

“…In the anammox stage, the primary functional bacteria were AnAOB ( Candidatus Kuenenia) and some DNB. The two-stage PN/A process enables the separation of functional bacteria, enhancing operational simplicity and efficiency( Jia et al, 2022 ).
