Full-scale Implementation of Partial Denitrification/Anammox (PdNA) IFAS

Abstract

Moving and fixed media have been installed in a full-scale partial denitrification with anammox process at HRSD’s James River Treatment Plant with the goal of improving treatment, saving carbon and aeration energy, and intensifying current processes. In the moving media configuration, anammox activity was observed after 93 days of carbon addition. Currently 0.46 ± 0.32 g/m2 /day of ammonia removal is observed across this zone. The fixed media, 62 days post carbon addition at the time of writing, is subject to an ongoing monitoring campaign for anammox.

Moving and fixed media have been implemented in HRSD's James River Treatment Plant, accompanied with a full-scale partial denitrification with anammox (PdNA) process to improve treatment, save both carbon and aeration energy, and achieve process intensification. 93 days after the addition of carbon, anammox activity was observed on the moving media.

Impact of Carbon Choice for PdN in Integrated PdNA System with Methanol Polishing

Abstract

This paper compares the impacts of three external carbon sources (fermentate, acetate, and methanol) when applied to a pilot system modeling a method for implementing integrated partial denitrification-anammox (PdNA) for nitrogen removal at DC Water’s Blue Plains Advanced Wastewater Resource Recovery Facility (WRRF).

Moving Towards PdNA Demonstration at Blue Plains AWWTP Using Primary Sludge Fermentate

Abstract

This paper shows the drivers and implementation approach we plan to use for partial denitrification anammox (PdNA) integration in the existing nutrient removal system at Blue Plains advanced wastewater treatment plant. Keywords: short-cut nitrogen removal, mainstream nitrogen removal, operations, process control, PdNA, fermentate, facilities planning, infrastructure Learning Objective: Understanding the specific application needs for implementation of partial denitrification anammox technology when using fermentate as a carbon source.

Optimization Strategies: HRSD, Virginia Beach, VA

Abstract

For the first time, mainstream anammox was successfully and consistently achieved in a full-scale WRRF. This was demonstrated by over a year of operating data in a deep-bed filter at the HRSD York River Treatment Plant. This paper will present the experiences and lessons learned from operating a full-scale PDNA filter at the HRSD York River Treatment Plant, important results from PDNA MBBR pilot testing, and design concepts for the installation of a full-scale PDNA MBBR.
