Product Description

One step solution from design, produce, installation, commissioning.
Dissolved air flotation (DAF) is one of the most important and effective process in the treatment of all types of water -industrial and urban wastewater treatment, water processing and water reuse of processes.



1.Dissolved air flotation is based on a Physics-chemical process which separates solid-liquid particles by the addition of very small air bubbles.These bubbles stick on solid particles and give them a high rate of ascent.Once in the surface, the solids and sludge are pulled mechanically to the hopper.
2.Finally, in the surface of the flotation unit a scraper system pulls the generated sludge to the hopper for collecting it and the clarified water is discharged in a spillway on the opposite side.
3.In the meanwhile, heavier particles that could not reach a lower density than water are kept in the sedimentation chamber to be recirculated at the beginning of the water treatment line to receive the appropriate treatment.

Dissolved air flotation gives a rate of ascent 5 times higher than settling speed in a conventional settling tank, thereby saving time and space.

It can be installed in different points of water treatment line due to multiple design possibilities of dissolved air flotation units.
1.In several occasions, dissolved air flotation system is installed at the beginning of the water treatment process, immediately after the pretreatment to remove fat and grease.,,.
2.It also can be implanted at the inlet of biological treatment for reducing pollutant load.In other many times it is placed at the final of water treatment line to clarify water before being discharged.
3.In desalination -in which the development of fiber glass is starting to consolidate as construction material- it  works to protect the membranes from the presence of algae in the water too.
4.Furthermore it can be installed at the top of the sludge treatment line as sludge thickener to reduce the volume.
