Understanding Nitrite Lock in Wastewater: A Disrupted Nitrification Process

by Erik Rumbaugh | Mar 19, 2025 | Uncategorized

Wastewater treatment is a carefully orchestrated process where microbial communities play a critical role in transforming harmful compounds into less hazardous forms. Among these transformations, nitrification—a two-step aerobic process—stands as a cornerstone of...

Nitrite lock or incomplete ammonia oxidation

by Erik Rumbaugh | Jul 30, 2024 | Wastewater Troubleshooting

Nitrite lock occurs when the ammonia (NH₄) doesn’t complete the full nitrification process, which typically involves the following steps: Ammonia Oxidation (NH₄ → NO₂): Ammonia is oxidized to nitrite by ammonia-oxidizing bacteria (AOB). Nitrite Oxidation (NO₂ →...
