Flotation is the most effective method of removing contaminants such as fats, suspensions, and petroleum substances.
Flotation is the most effective method of removing contaminants such as fats, suspensions, oil-derived substances and other undissolved substances found in industrial wastewater. The separation of these contaminants takes place in chemical processes using coagulants and flocculants (polymers). After separation, separation takes place using a water-air mixture in the flotation chamber. The resulting sludge is discharged outside the system and possibly dewatered before being disposed of, e.g. in a biogas plant.
