What is 'air flotation' 🧑‍🔧

Warm greetings, my friend! The goal of this page is to clarify "What is 'air flotation'" by addressing common misunderstandings.

A liquid-solid separation process wherein the main mechanism of suspended-solids removal is the change of apparent specific gravity of those suspended solids in relation to that of the suspending liquid by the attachment of small gas bubbles formed by the release of dissolved gas to the solids.

’Air flotation’ is simply the production of microscopic air bubbles, which enhance the natural tendency of some materials to float by carrying wastewater contaminants to the surface of the tank for removal by mechanical skimming.

These are a few popular questions people ask:

Air flotation

How do air flotation systems work...

Dissolved air flotation, the most common approach, works by attaching small bubbles of air to suspended solids. The bubbles are generated by saturating a recycled stream of water with air under pressure, then releasing the pressure rapidly to produce clouds of microbubbles.

What are the importance of flotation in air...

The aim of flotation is to remove oils, fats, suspended matter and undissolved particles from wastewater. Flotation can be used as a pre-treatment in the purification process, for biological purification, for example, but is often also used as the only step in the purification process.

What type of flotation is used in water treatment...

Dissolved air is the most common type of flotation gas used in potable water treatment. The dissolved air flotation (DAF) process mixes a clarified stream from the outlet of the unit with air at 3–9 bar, to produce a supersaturated (compared with saturation at atmospheric pressure) solution of air in water.
