process engineered water equipment Dissolved air flotation (DAF) is an effective way of treating wastewater treatment. It is important to know how water is treated because everyone uses water. This knowledge helps you understand how the water that you use is cleaned. This guide teaches you wastewater treatment using the DAF process.

网页This work presents a discussion of the induced gas flotation process as a method for cleaning waste waters by removing suspended contaminants using froth flotation. The origin of the process is briefly reviewed, and a comparison is made to dissolved air flotation showing that the 2 processes have both similarities and differences.

Flotation experiments were carried out in a 5 L Denver flotation cell. Initial solid concentration was about 18% by weight. The pulp level was constantly adjusted by the addition of synthetic water of suitable quality. The natural pH was about 7. NaOH was used to adjust the pH of all tests to 11.3.

The flotation process refers to the general term for the ore pulp flowing through each operation during ore flotation. In the flotation operation, different types of ore should be treated with different flotation procedures. Therefore, the flotation process can reflect the process characteristics of the ore.
