Sludge treatment − dissolved air flotation thickening
How DAF works. Dissolved air flotation (DAF) provides thickening of sludges (i.e. thickens the sludge) by encouraging the solids to float to the surface, rather than allowing them to sink as in gravity thickening.. DAF is applied to increase the sludge solids concentration when these solids are neutrally buoyant (i.e. neither sink nor float) and so cannot be readily removed …

What is sludge thickener scraper?
A sludge thickener scraper is a mechanical tool used in wastewater treatment facilities to remove solid sludge from settling tanks. As water and waste enter the tank, solids settle at the bottom, forming a layer of sludge that needs to be removed regularly.

Clarifier Designs & Services
Spiral Scraper Spiral scraper type clarifiers utilize long–sweeping, curved scraper blades to move solids across a basin floor. They are similar to scraper–type clarifiers in that they drag settled solids to the collection area, however, they can more quickly remove these solids and thus maintain lower sludge blankets in some applications.
