This is the internal process of our 500-ton-per-day Dissolved Air Flotation (DAF) unit, specifically designed for high-fat petroleum wastewater.
Specialized chemicals are dosed to break the stable oil emulsion. This causes dispersed oil droplets and suspended solids to coalesce into larger, separable clusters called “flocs.” Heart of the process: Supersaturated water is released, creating a dense cloud of micro-bubbles.
These bubbles act as targeted carriers, adhering to the flocs The bubble-floc aggregates become lighter than water and float upward en masse, creating a distinct sludge layer on the surface. It’s a rapid, efficient, and visible “snow-globe” effect.
A slow-moving scraper skims the concentrated sludge from the surface. What remains is clarified water, free from the vast majority of fats, oils, and suspended solids, ready for the next stage of treatment.
The entire process is a perfect combination of physical and chemical principles—efficient, stable, and clearly observable.
