DheyTécnica’s Dissolved Air Float (DAF), was designed to carry out the removal of suspended solids, oils and fats present in effluents, through a physical chemical process, or only physical.
Microbubble generation system through multiphase pump and saturator, microbubble distribution system by dispersers installed in the lower part of the flotation tank.
Main Applications:
DheyTécnica Flotation System Efficiencies:
| PARAMETERS | PHYSICAL/CHEMICAL OPERATION | PHYSICAL OPERATION |
| DBO | 85 – 92% | 40 – 60% |
| DQO | 75 – 80% | 60 – 50% |
| O&G | 95 – 98% | 40 – 70% |
| Suspended solids | Higher than 95% | 40 – 65% |
| Nitrogen | Higher than 50% | 20 – 30% |
Small installation areas, due to high operating rates
Low power consumption
High efficiency in the removal of loads, due to the ideal incorporation rate and distribution of microbubbles and hydraulic detention time appropriate to each application
Lower consumption of chemical products when compared to the conventional system
Lower sludge volume generation due to system densification efficiency and high performance in the removal of organic load, oils, greases and suspended solids
Homogenized
Effluent
Clarified liquid for subsequent
routing to the secondary system.
Densified residue for later separation
in the Decanter or Centrifugal Tridecanter
