Dissolved air flotation (DAF) is a water treatment process that removes suspended solids from water using air. This separation is achieved by dissolving air into water under pressure, and then releasing the air at atmospheric pressure in a flotation tank. This module will describe common applications of the dissolved air flotation (DAF) process and the main steps of the DAF process.

Learning Objectives

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

  • Describe common applications of the Dissolved Air Flotation (DAF) process
  • Describe the main steps of the DAF process
  • Describe the equipment utilized in a DAF system
  • Identify chemicals commonly used as coagulants and flocculants in DAF systems
  • Describe coagulant and flocculant chemicals used in DAF systems
  • Identify hazards associated with DAF system

Key Questions

The following key questions are answered in this module:

How are tiny fiber fines removed from suspension in a dissolved air flotation system?
Tiny fibers attach to small air bubbles and are carried to the surface of the DAF clarifier.

What types of chemicals are added to the DAF process to assist in particle separation?
Coagulants and flocculants can be added to DAF units in order to increase their separation efficiency.

What is the purpose of prescreening ahead of DAF units?
Prescreening the feed stream to a DAF unit reduces the solids loading on the unit.

Where in the DAF unit is new feed added?
Incoming feed is released at the bottom of the unit, giving a chance for dissolved air bubbles to form and collect suspended particles as they rise.

What happens to the separated material that floats to the top of a DAF unit?
Separated material is skimmed from the surface of the DAF unit. If the unit is treating paper machine white water the float may be recycled.

Sample Video Transcript

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

Dissolved air flotation, or DAF, is a water treatment process that removes suspended solids from water using air. This separation is achieved by dissolving air into water under pressure and then releasing the air at atmospheric pressure in a flotation tank. The released air forms tiny bubbles which adhere to the suspended solids in the water causing the solids to float to the surface where they can be removed by a skimming mechanism. Chemicals can be added to the feed water to improve solids removal. The DAF process can be used to clarify fresh water, processed water, and waste water so that it is suitable for use or discharge. In some cases, the solids are collected for reuse. Common applications include clarification of municipal water and waste water and process water in paper making operations.

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 provided.

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. Available languages are normally displayed in the Course Details section on each course page.
