To further reduce the energy consumption in the wastewater biological nitrogen removal
process, partial nitrification and its integrated processes have attracted increasing attentions …

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 …

Partial denitrification (PD) has been proved technically feasible and economically favorable
to produce nitrite (NO 2--N) for anammox. To obtain stable NO 2--N accumulation, the effects …

Human urine contains 9 g/L of nitrogen (N) and 0.7 g/L of phosphorus (P). The recovery of N
and P from urine helps close the nutrient loop and increase resource circularity in the …

MFC anodic denitrification is more suitable for the coexistence of organic matter and nitrate
in actual sewage, but the traditional carbon source has some problems such as high cost …

The effect of phosphate concentration on the anammox-HAP process was investigated in
this work. A high total nitrogen removal efficiency (> 82.6%) and a stable total phosphate …

Partial-denitrification (PD) has previously been demonstrated to be another pathway for
nitrite production, which provides a cost-effective approach for nitrate (NO 3−-N) removal …

Bio-cathode denitrification is a new and unique technology for autotrophic nitrogen removal,
which uses electricity instead of chemical matter as electron donor. Functional …

The biocathode microbial electrochemical system (MES) was promising for wastewater
treatment. However, the residual dissolved organic matter in catholyte caused the excessive …

Salt-tolerant aerobic granular sludge (SAGS) technology is currently a topic of significant
interest in research focused on the treatment of saline wastewater. However, the structural …
