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.
