Enhancement of microbubble generation in a pressurized dissolution process by packing the nozzle with porous ceramics
The pressurized dissolution method is often used for microbubble generation. However, the main disadvantage of this method is that a large amount of energy (more than 0.3 MPa) is required to generate many microbubbles, each of which have a diameter of several dozen μm. To overcome this problem, we investigated the effectiveness of porous ceramic when used as the packing material in the ...

The development and application of centrifugal flotation systems in wastewater treatment
Flotation as a wastewater treatment technique is designed to remove all particles generally encountered as very fine emulsions, suspended solids, and colloids from wastewater. Historically, Dissolved Air Flotation (DAF) has been used to achieve this removal. More recently, other flotation techniques such as induced air, electro, cavitational, and Centrifugal Flotation Systems (CFS) have been ...

Two- and three-phase simulations of an ill-functioning dissolved-air flotation tank
Computational Fluid Dynamics (CFD) simulations were employed to examine the performance of a large-scale Dissolved-Air Flotation (DAF) tank. The tank was ill-functioning as it was operated with bubbles larger than designed for. Different multiphase models, turbulence models and boundary conditions for the free surface of the tank were tested in 2D simulations. The simulation results were assessed ...

One-step analysis of bubble-particle capture interaction in dissolved-air flotation
The capture of particles by air microbubbles in dissolved air flotation has been analysed using a one-step (holistic) approach, which numerically solved the motion equation (with the inclusion of microhydrodynamic resistance functions and surface forces) for both the bubble-particle collision and attachment interactions. Model predictions with the inclusion of non-DLVO attractive surface force ...

The design and operation of conventional and novel flotation systems on a number of impounded water types
This paper describes the design of conventional Dissolved Air Flotation (DAF) systems, and the novel Counter Current Dissolved Air Flotation Filtration (COCODAFF®) process. The operation and performance of these plants on a variety of water types in the United Kingdom and South Africa is also described. The advantages of flotation processes for the treatment of impounded waters either high in ...

Dissolved Air Flotation
Dissolved air flotation (DAF), which is mainly used in wastewater treatment system, is a reliable and proven process for purification. DAF is used for the easy separation of suspended matters in liquids. The DAF system works by saturating the process water with air under high pressure which is then released to normal pressure and piped into the wastewater tank. The micro bubbles generated during ...

Two-phase simulations of an off-nominally operating dissolved-air flotation tank
The flow patterns of the contaminated water and the air bubbles inside a large-scale Dissolved Air Flotation (DAF) tank were examined using CFD modelling. The DAF tank was operating off-nominally in the sense that it was supplied with bubbles larger than originally designed for. Attention was drawn to the location for air injection and the effect of having more than one-size bubbles in the tank, ...
