Flotation

Dissolved air flotation is one of the most effective physicochemical methods for treating industrial wastewater. The process involves saturating water with fine air bubbles, which carry contaminants to the surface in the form of foam that can be mechanically removed.

This method enables efficient removal of suspended solids, fats, oils, and petroleum-based substances, significantly reducing BOD and COD levels.

Flotation technology greatly reduces the load on the biological treatment stage or – if no such stage exists – allows for compliance with maximum allowable concentrations (MAC) for wastewater discharged to the sewage system.
