The growing global population's demand for ammonium has triggered an increase in its
supply, given that ammonium plays a crucial role in fertilizer production for the purpose of …

In nature, selenium is actively cycled between oxic and anoxic habitats, and this cycle plays
an important role in carbon and nitrogen mineralization through bacterial anaerobic …

Nitrogen and phosphorous are key pollutants in wastewater to be removed and recovered
for sustainable development. Traditionally, nitrogen removal is practiced through energy …

Elimination of nitrogen pollution from wastewater containing high-strength nitrate (NO 3−-N)
is a significant issue to prevent deterioration of water quality and eutrophication of receiving …

Biodecolourization of azo dye and removal of ammonium by aerobic granular sludge (AGS)
was investigated under different growth conditions. AGS not previously exposed to azo dye …

Nitrite production in a partial denitrifying (NO 3−-N→ NO 2--N) upflow sludge bed (USB)
reactor equipped with gas automatic circulation (GAC) was investigated at ambient …

Abstract Effect of influent COD/NO 3− ratios (2.0–5.0) on partial denitrification (PD, NO 3− to
NO 2−) was investigated by seeding denitrifying phosphorus removal (DPR) sludge at …

Denitrification of high strength nitrate wastewater was investigated in granular sludge
sequencing batch reactors (SBRs) with the objective of optimizing electron donor …

Partial sulfide autotrophic denitrification (PSAD) has been proposed as a promising process
to achieve elemental sulfur recovery and nitrite accumulation, which is required for …

Formation of aerobic granular sludge (AGS), process performance and microbial community
structure were investigated in lab-scale sequencing batch reactors (SBR) operated without …
