Separation characteristics in dissolved air flotation - pilot and full-scale demonstration

Cimbritz, Michael LU and Jönsson, Lennart LU (2003) In Water Science and Technology 48(3). p.89-96
Abstract
This study presents practical implications for particle separation in Dissolved Air Flotation (DAF). The objectives were to localise where particles are separated from the water phase and to determine what particles, in terms of size, are removed by the DAF-process. Both pilot- and full-scale plants were investigated. Particle sizes were analysed with a light-blocking particle counter and an optical borescope was used for visualisation of particle-bubble aggregates. It was found that particles are preferably separated upstream in the process, i.e. close to the contact zone. Furthermore, separation efficiency for particles increased with increasing particle size.
