Flotation devices are designed to remove grease, oil and fine suspended solids from wastewater. They work by saturating the water with small air bubbles, which lift the contaminants to the surface, where they form foam. This foam is collected by scrapers for further removal.
Flotation devices effectively purify water in food, oil refineries, industrial and municipal wastewater treatment plants. This technology can remove small fractions of fat, oil, glue and other floating contaminants, improving the quality of the purified water.
