Nitrogen removal from wastewater
Biological nitrogen removal (BNR) encompassing well-established and emerging technologies offer an effective process for removal of nitrogen from wastewater and side-streams. The present study provides a comprehensive review of BNR based technologies that include conventional N/DN, PN-ANAMMOX, and simultaneous deammonification and denitrification.
For the treatment of N pollutants in wastewater, biological nitrogen removal (BNR) technology is an economic and effective method [19]. Particularly, the activated sludge process is a typical BNR technology, possessing flexible and diverse process modes, strong impact load resistance, and stable pollutant removal performance [20].

Biological Nutrient Removal : Design Guidelines for Reliable Nitrogen & Phosphorus Control Reliable control of nitrogen and phosphorus depends on design choices, sizing, and operational control rather than hopeful tuning after startup. These biological nutrient removal design guidelines translate standards and field-proven practice into clear decision rules, numeric setpoints, control logic ...
