Leveraging Densified Activated Sludge and Partial Nitrification/Denitrification/Anammox within an Integrated Advanced Water Treatment Facility for Large-Scale Potable Reuse

Abstract

The Los Angeles County Sanitation Districts (Districts) have been exploring options for implementing nitrogen removal at the Joint Water Pollution Control Plant (JWPCP), a 400-MGD capacity high purity oxygen activated sludge (HPOAS) facility, due to potential reuse and regulatory drivers. This paper summarizes pilot-scale demonstrations of a secondary BNR (Densified Activated Sludge, DAS) and a tertiary BNR (tertiary moving bed biofilm reactor, TMBBR). These approaches has proven successful at meeting the nitrogen removal targets and provide program enhancements, including densification and PANDA/PdNA.

The Los Angeles County Sanitation Districts are exploring nitrogen removal options at the Joint Water Pollution Control Plant (JWPCP), a 400-MGD capacity high purity oxygen activated sludge (HPOAS) facility, to address potential reuse and regulatory drivers. Two potential approaches developed were a three stage A2O configuration and a tertiary moving bed biofilm reactor. Both approaches were successfully pilot tested and demonstrated the ability to meeting nitrogen removal targets.

Successful Full-scale Demonstration of Nitrogen Removal in a High Purity Oxygen Facility with No Infrastructure Modification

Abstract

The Los Angeles County Sanitation Districts (Districts) have been exploring options for implementing nitrogen removal at the Joint Water Pollution Control Plant (JWPCP), a 400-MGD capacity high purity oxygen activated sludge (HPOAS) facility, due to potential reuse and regulatory drivers. This paper summarizes a fullscale demonstration of a novel concept of utilizing HPOAS for nitrogen removal with no infrastructure modification. This approach has proven successful at providing robust nitrogen removal and provides a significant benefit to the JWPCP and potentially other HPOAS facilities.

The Los Angeles County Sanitation Districts are exploring nitrogen removal options at the Joint Water Pollution Control Plant (JWPCP), a 400-MGD capacity high purity oxygen activated sludge (HPOAS) facility, to address potential reuse and regulatory drivers. Through a full-scale demonstration of the high-purity oxygen Ludzack-Ettinger (HPOLE) process, robust nitrogen removal was achieve, indicating that HPOLE provides a significant benefit to the JWPCP and is scalable to other HPOAS facilities.
