Secondary wastewater treatment is the second stage in wastewater treatment, following what is known as primary treatment. Secondary treatment takes suspended solids and dissolved organic material, captures the solids, and removes greater than 85% of the biological oxygen demand, also known as BOD. Secondary treatment is a biological process which utilizes bacteria to remove BOD followed by secondary clarification.

At the end of this module, you will be able to:

  • Define secondary wastewater treatment
  • Identify the purpose of secondary wastewater treatment
  • Define BOD and COD
  • Describe the different forms of secondary wastewater treatment plants
  • Identify and describe the key equipment and process flows of secondary wastewater treatment
  • List the bacterial growth factors in secondary wastewater treatment plants
  • Describe the principles of a secondary clarifier

The following key questions are answered in this module:

What parameters are typically monitored in order to meet discharge permits?
Some of the parameters monitored include flow, BOD, suspended solids and pH.

What are growth pressures in secondary treatment pond?
Any factor which will affect the health of the microbial community in a treatment vessel is called a growth pressure.

What is the difference between an oxidation basin and an aerated stabilization basin?
Oxidation basins rely on natural diffusion to get the oxygen that microbes in the water need to metabolize organic matter. Aerated stabilization basins use mechanical means to increase the transfer of oxygen.

What is BOD?
BOD is Biochemical Oxygen Demand, it is a measure of the concentration of biologically consumable organic materials in a water sample.

What is anaerobic treatment?
Aerobic microbes need oxygen to grow and thrive, anaerobic microbes live and consume organic material in an oxygen-free environment.

Below is a transcript of the video sample provided for this module:

The activated sludge process introduces recycled sludge from the secondary clarifier downstream of the basin into the feed. The additional microorganisms and additional oxygen added to support them increases the efficiency of a basin beyond that of a simple aerated basin. Some activated sludge systems are enclosed and oxygen enriched air is introduced into the enclosure. The higher levels of oxygen, once again, increase the efficiency of BOD reduction. In evaluating the types of systems there is a trade off. As they become more efficient they become more complex and expensive to operate.

Ask a Question

Sorry, we're missing some information

I would like to have several employees take multiple courses. How can I set that up?

We're in the process of making bulk course and multiple user purchases easier. But for now, you can order multiple courses and contact us with details on who you'd like to assign courses to. We can set up each user's training plan and make sure everyone gets the eLearning assignments they need.

Can I get a free full-length preview of a course to see what this course covers?

While we do our best to offer details on course contents, we don't normally offer full-length previews. But please contact us with more details for a better understanding of what your organizaton needs and how we can help.

Do I get a certificate when I complete a course?

Yes. All of our courses allow you to print a completion certficate upon successfully passing the integrated test at the end of each eLearning course.

How do I log in to take a course that I have already paid for?

You'll receive an email with login details moments after you purchase your pay-per-view (PPV) course. Just click the login link and enter the user name and password provieded.

Do you have courses in different languages?

Yes. While all of our courses are originally produced in English, we develop many courses in a growing number of languages, including Chinese, Dutch, German, Italian, Japanese, Korean, Polish, Portuguese, Russian, Spanish, Tamil, and Thai. Availabl languages are normally displayed in the Course Details section on each course page.
