Dissolved Air Flotation Specification


Enviro Concepts Dissolved Air Flotation (DAF) are compact, low maintenance DAF units are engineered to remove a wide range of solids and hydrocarbons.


Enviro Concepts DAF systems are engineered to efficiently remove suspended solids, fats and oils, BOD, COD and heavy metals from a wide variety of water and wastewater sources. These units are pre-engineered, pre-assembled and factory tested minimising site installation and start-up time. Simple connections and easy to set up controls make these units ready for quick on-line service.

The DAF unit emits minute air bubbles which bind with the oils and fats, precipitated metals and suspended solids increasing their ascending ability. This results in a floating sludge layer that can easily be removed by a mechanical scraper.
