Abstract

The release of excessive nutrients in coastal areas can cause severe damage to the marine environment through algal blooms, eutrophication, and a reduction in biodiversity. Such nutrients are typically transported to the ocean by wastewater discharges or agricultural runoff. This project analyzed technologies specifically designed to remove nitrogen from wastewater. A comparative technology pilot was conducted for nitrogen reduction technologies at water utilities with footprint limitations. The pilot identified the technologies best suited to reduce nitrogen in wastewater to reduce discharge concentrations and loads to receiving waterbodies. The findings are posted below in three final reports. There is also one overarching Executive Summary detailing high-level results from all the technologies investigated.
