Introduction Dissolved Air Flotation (DAF) is frequently the unit process of choice when dealing with low-density solids, algae, or fats, oils, and grease (FOG)—contaminants that defy gravity settling. However, a surprising number of DAF installations fail to meet performance guarantees not because the tank is the wrong size, but because the whitewater system is improperly […]

Partial Flow Dissolved Air Flotation (DAF) systems are a type of water treatment process that excels in the removal of suspended solids, oils, and greases from industrial wastewater. This method of treatment is designed to operate with a portion of the total flow, treating and recycling a percentage of the processed water. By introducing air […]

Packed column DAF, or Dissolved Air Flotation, is an innovative water treatment technology that efficiently separates contaminants from water. DAF systems are particularly effective for the removal of solids, oils, and greases that are lighter than water and thus can be floated to the surface with the aid of fine air bubbles. Packed column DAF […]

Recycle flow dissolved air flotation (DAF) is a water treatment process that leverages the power of microscopic air bubbles to separate and remove small suspended solids, grease, or oils from wastewater. Utilizing a pressurized stream of air, tiny bubbles attach to the particles, causing them to float to the surface, where they form a layer […]
