Traditional activated-sludge treatment technologies, such as anaerobic/anoxic/aerobic processes, oxidation ditch and sequential batch reactors, play a crucial role in the removal of nitrogen phosphorus from municipal wastewater. The synergistic interactions among functional microorganisms, primarily nitrogen-removal organisms phosphorus-accumulating organisms, are paramount these processes. However, traditional activated sludge technology consumes large amounts energy produces substantial volume waste-activated sludge, necessitating upgrade wastewater plants (WWTPs) focusing on sustainable development goals. This review analyzes characterizes key microorganisms (Nitrosomonas, Nitrosospira, Nitrobacter, Nitrospira, Thauera, Pseudomonas, Candidatus Brocadia, Kuenenia, Accumulibacter) involved treatment. It also explores impact operating conditions, influent quality, reactor configurations regulation for efficient nutrient removal, with emphasis upgrading reconstructing techniques full-scale anaerobic ammonium (anammox) Integrated fixed-film sludge-based (IFAS), aerobic granular (AGS), moving bed biofilm (MBBR) technologies promising to enhance transform conventional realizing new engineering applications practices. Other developments use heterotrophic denitrifying bacteria Thauera anammox (Candidatus Brocadia Kuenenia) mainstream partial denitrification/anammox which potentially expandable WWTPs.

Granular activated carbon (GAC), a porous carbon-based material, provides increased attachment space for functional microorganisms and enhances nitrogen removal by facilitating extracellular electron transfer in the anammox process. This study investigates effects of GAC on biosynthesis microbial secretions (MESs) explores roles these activities. Four lab-scale reactors were operated: two downstream UASB (D1 D2) receiving effluents from upstream (U1: no-GAC, U2: yes-GAC). Our results indicate that MESs enhanced with addition GAC. The effluent U2 exhibited 59.62 % higher amino acid content than U1. These contributed to an increase loading rate (NLR) reactors. Specifically, NLR D1 130.5 142.7 g N/m3/day, D2, it escalated 137.5 202.8 likely through acting as cross-feeding substrates or vital nutrients. D2 also showed bacterial activity, enriched Ca. Brocadia population hao gene abundance. Furthermore, this revealed sludge has significantly polymeric substances (EPS) (48.71 mg/g VSS) larger average granule size (1.201 ± 0.119 mm) compared sludge. Overall, GAC-stimulated may have performance
