Rapid temperature changes tend to cause more problems than gradual drift in WW. Even with slow increase in temperatures, you reach inflection points where system drifts above the growth range of most common mesophilic organisms. Most common genera in WW thrive up to...

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 →...

This wastewater indicator organisms poster relates observed protozoa and metazoa populations to F/M and MCRT. We find it useful to post near the lab microscope to help with interpretation and finding where you are on the growth curve.
