Dissolved Air Flotation


Dissolved Air Flotation (DAF) System

Our Dissolved Air Flotation (DAF) system is a highly efficient pre-treatment step for the separation of suspended solids and oil and grease contaminants from wastewater. The compact LESI DAF system boasts high removal rates, 99.9% runtime and a robust design. The compact DAF can either be integrated in a complete solution or offered as a single product for your wastewater treatment.

The Science Behind the Dissolved Air Flotation (DAF) System

LESI Dissolved Air Flotation (DAF) System forces oil particles to coalesce then float to the surface where they are skimmed and remediated. Use of the LESI DAF increases particle separation for more effective removal rates.


Proven Non-Plugging Technology

The DAF’s proprietary hydrocarbon removal system and polishing filter increases contaminant removal rates by capturing oils, VOCs and sludges without clogging the system.

Low Maintenance

The DAF is designed with minimal moving parts for fewer breakdowns.

Compact Footprint

The LESI DAF has a minimal footprint.
