N2O Emissions from a Full-Scale Membrane Bioreactor Treatment Plant using Aqueous and Gaseous Monitoring Techniques
Abstract
This study quantifies N2O emissions from a membrane bioreactor (MBR) Water Reclamation Facility (WRF) and compares continuous, on-line aqueous and gaseous monitoring techniques. This methodology offers detailed N2O emissions data with
- continuous measurement,
- a long period of data collection, and
- a study location at a plant with covered basins and an off-gas control system. It is of interest to determine if each measurement method yields similar data, since liquid analyzers are more practical for most plants to install. Thus, this study may serve as encouragement to utilize aqueous analyzers without offsetting precision.
N2O from a full-scale MBR treatment plant in Washington state was measured on-line for 5.5 months using gas-phase and liquid-phase analyzers. Methodologies from the different analyzers were compared and the plant’s average emission factor and annual emission estimate were determined. Factors influencing N2O emissions were investigated with correlation analysis using the plant’s operational data.
