Nitrification & Denitrification in Activated Sludge Treatment 

Nitrification & Denitrification in Activated Sludge Treatment

November 9, 2021 | Online :: Central Time

Ammonia removal is becoming more common in Wastewater plant discharge permits and is one of the most important and challenging process to maintain. Nitrification is the oxidation of that ammonia by converting it, in a two-step process, to nitrate using aerobic bacteria. Denitrification occurs in an anoxic environment where bacteria use the oxygen, from the nitrates, as they consume BOD and the nitrogen is released into the air. This process sounds simple but mastering it on a consistent basis can be difficult even for the most experienced operator.

The EUCI Nitrification & Denitrification in Activated Sludge Treatment course will review the general treatment operations and protocol for nitrification and denitrification wastewater treatment. This basic to intermediate course has been developed for all professionals in the wastewater field to provide an understanding of how this process can be applied to various wastewater plants. Proper operation and maintenance of the Nitrification process in biological and municipal wastewater treatment facilities can add to the plant’s sustainable use and reuse of water.

Learning Outcomes

  • Describe and identify the Activated Sludge process elements: components, requirements, differing designs, mathematical equations, etc.
  • Practice the manipulation of the Activated Sludge process to remove nutrients through nitrification and denitrification or phosphorus uptake
  • Review how inventory control (SRT) effects nutrient removal and disinfection
  • Detect and mitigate common challenges faced in daily wastewater plant operations
  • Calculate important equations relating to both BOD and nutrient removal
  • Utilize the chemistry basics of Nitrification (like what NH3 -> NO2->NO3 means)
  • Troubleshoot common problems relating to nutrient removal and activated sludge

Online Delivery

We will be using Microsoft Teams to facilitate your participation in the upcoming event. You do not need to have an existing Teams account in order to participate in the broadcast – the course will play in your browser and you will have the option of using a microphone to speak with the room and ask questions, or type any questions in via the chat window and our on-site representative will relay your question to the instructor.

  • IMPORTANT NOTE: After November 30 you will not be able to join a Teams meeting using Internet Explorer 11. Microsoft recommends downloading and installing the Teams app if possible. You may also use the Edge browser or Chrome.
  • You will receive a meeting invitation will include a link to join the meeting.
  • Separate meeting invitations will be sent for the morning and afternoon sessions of the course.
    • You will need to join the appropriate meeting at the appropriate time.
  • If you are using a microphone, please ensure that it is muted until such time as you need to ask a question.
  • The remote meeting connection will be open approximately 30 minutes before the start of the course. We encourage you to connect as early as possible in case you experience any unforeseen problems.
