Ammonia Removal for Lagoons

Patrick · May 29, 2020

This 60 minute webinar presents an overview of the lagoon ammonia removal process and an evaluation of options to achieve compliance.

• Why lagoon ammonia is being regulated
• The nitrification process
• 6 key factors for nitrification: BOD, dissolved oxygen, pH, biomass, temperature, mixing
• Nitrification options: including mechanical plant replacement, modified discharge, in-lagoon media, aerated rock filter, nitrification reactor
• Lagoon ammonia removal case studies
