Generally, within routine flotation operation, samples are obtained on a shift basis and take a number of hours to process. On-line instruments are used to measure grade, however, these instruments are relatively expensive to maintain and may have low sample frequencies. Therefore, the response time to deviations from the target grade is …
Air-particle or air-bitumen attachment is an essential step for a successful flotation and is strongly dependent on the chemistry of a flotation system. In a broader sense, induction time is defined as the minimum times required for film thinning, film rupture and three-phase contact line expansion.
Dissolved Air Flotation (DAF) has received more attention recently as separation technique in both drinking water as well as wastewater treatment.
