Many municipal wastewater treatment plants using oxidation ditch processes struggle with unstable ammonia and total nitrogen removal. Common issues include low-temperature performance drops, floating sludge, and inconsistent system stability.
In most cases, the root causes come down to two key factors:
▪️ Unbalanced C/N ratio (insufficient carbon source)
▪️ Uneven dissolved oxygen (DO) distribution
When these challenges occur together, nitrification slows down and denitrification becomes inefficient—directly impacting overall treatment performance.
