The Role of Sulfides in Anaerobic Digesters

by Erik Rumbaugh | Apr 3, 2025 | Anaerobic digester, Wastewater Troubleshooting

Sulfides are primarily produced through the activity of sulfate-reducing bacteria (SRB). These microorganisms use sulfate as an electron acceptor, generating hydrogen sulfide (H₂S) as a byproduct. While this process is natural, the accumulation of sulfides can have...

The Role of Filamentous Bacteria in Wastewater Treatment: Not All Bad

by Erik Rumbaugh | Feb 26, 2025 | Filamentous Bulking, Uncategorized, Wastewater Troubleshooting

When it comes to wastewater treatment, filamentous bacteria often get a bad rap. However, these microorganisms play a crucial role in the treatment process, especially when present in moderate numbers. Let’s dive into how filamentous bacteria contribute to...

Impact of Surfactants on Wastewater Treatment Plants

by Erik Rumbaugh | Feb 3, 2025 | Uncategorized, Wastewater Troubleshooting, Whitepaper

Surfactants, or surface-active agents, are among the most common chemcials used in both households and industrial facilities. Found in everything from personal care products to industrial cleaners, these chemical compounds reduce surface tension between two...

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 →...
