A novel SNPR process for advanced nitrogen and phosphorus ...

01-03-2020· For achieving energy-efficient wastewater treatment, a novel simultaneous nitrogen and phosphorus removal (SNPR) process, which integrated anammox, endogenous partial-denitrification and denitrifying dephosphatation in a sequencing batch reactor with granular sludge was developed to treat mainstream wastewater.

The Evaluation of Enhancing Biological Phosphorus Removal ...

hydrocyclones, with the intent of improving settleability and biological phosphorus removal (Bio-P) for mainstream processes. Improved settleability would allow for increased capacity in the secondary clarifiers which prevents the loss of biomass and subsequent treatment disruption, especially during wet weather scenarios.

Mainstream Deammonification with Biological Phosphorus Removal

This project seeks to further the prevention and control of harmful algal blooms (HABs) by improving full-scale applications of shortcut nitrogen removal processes at water resource recovery facilities (WRRFs). Specifically, the project will focus on increasing nitrite availability for anaerobic ammonium oxidizing bacteria (anammox) in mainstream systems via partial denitrification.

The occurrence of enhanced biological phosphorus removal ...

Mainstream partial nitritation and Anammox (PN/A) has been observed and studied in the step-feed activated sludge process at the Changi water reclamation plant (WRP), which is the largest WRP (800,000 m 3 /d) in Singapore. This paper presents the study results for enhanced biological phosphorus removal (EBPR) co-existing with PN/A in the activated sludge process.

Development of novel denitrifying nitrite accumulation and ...

For achieving mainstream anaerobic ammonium oxidation (Anammox), there is a need to achieve organic carbon and phosphorus removal meanwhile supplying nitrite (NO2–-N). Based on this demand, a novel anaerobic/anoxic/aerobic operated denitrifying nitrite accumulation and phosphorus removal (DNAPR) process was proposed for treating synthetic municipal and nitrate (NO3–-N) wastewaters ...

1. The BCFS® process (Biological–chemical phosphorus and nitrogen removal) (Van Loosdrecht et al. 1998) is a modification of the UCT design where part of the anaerobic supernatant is sent to the sludge thickener where iron chloride is dosed. Thus, EBPR is combined with chemical precipitation of P. 2.
