Sludge treatment − dissolved air flotation… | Sludge Processing
The DAF process works by dissolving air under pressure in water to achieve saturation concentrations. When the pressure is released, air is precipitated as small bubbles which rise through the vessel. The bubbles come into contact with the sludge particles, sweeping them up to the surface where they form a scum.
Flotation

Mechanical Dewatering
Loading is stopped during resting. Dewatered sludge after 10 years' operation could reach an approximate height of 1.2–5 m, with a dry solids content of 40–50% w/w or higher, depending on the climatic conditions. Following emptying, the beds are re-established. Dewatered sludge is either spread on land or disposed in landfills.
Water Handbook
Sludge Drying Beds. Sludge drying beds consist of a layer of sand over a gravel bed. Underdrains spaced throughout the system collect the filtrate, which usually is returned to the wastewater plant. Water is drained from the sludge cake by gravity through the sand and gravel bed. This process is complete within the first 2 days.
SELECTION OF MECHANICAL FLOTATION EQUIPMENT
Mechanical flotation cells can be broken down into two broad categories based on how air is introduced to the cell. In a self aspirated flotation cell air is introduced to the slurry, the vacuum created by the rotorusing . In a forced air flotation cell air is generated external to the cell by a low pressure blower,, and pumped down the
