The development and application of the hybrid centrifugal - dissolved air flotation system for wastewater treatment
Abstract Solid/liquid separations are integral part of any wastewater treatment system. Particles heavier than water are commonly separated in sedimentation clarifiers. On the other hand, particles with densities lower than that of water are most often separated with flotation systems. This manuscript describes the development of hybrid centrifugal - dissolved air flotation system. The system was ...

Simple protocols for assessing dissolved air flotation systems: quantification of released air, bubble density and cloud patterns
Dissolved air flotation (DAF) systems are useful for many water treatment applications. Optimizing a DAF system can be very difficult and complicated due to a multitude of variables that contribute to effective separation. Pressure, temperature, retention time and air mixing affect the ability of the saturator to increase air solubility, while baffle heights, flow rates and recycle ratios ...

Flotation Without Dissolved Air: Charged microbubbles for enhanced removal of suspended solids in wastewater applications.
For over a century, various forms of Dissolved Air Flotation (DAF) systems have been employed for the removal of suspended solids, and fats, oils, and grease from wastewater. The amount of air that can be dissolved in DAF systems is limited by the laws of physics and is usually less than 2 – 4% air by volume. The recirculated “whitewater” is drawn and created from underflow of ...

Dissolved air flotation (DAF) for biomass recovery from algal ponds
This work evaluated the performance of a dissolved air flotation (DAF) system for biomass recovery from the effluent of algal ponds used for sewage treatment in Northeast Brazil. Two different coagulants and effluent samples were tested following a random-factor experimental design (34–1–4 factors and 3 levels), in triplicate. Factor analysis showed that coagulant dose was the most important ...
