Fig. 1 shows RTD data from forced-airflotation cellsof (a) 100 m 3 and (b) 300 m 3, with effective residence times of 4.7 and 4.4 min, respectively (Yianatos et al., 2015). Fig. 1a shows a larger concentration in the first seconds.This was modelled as a by-pass flow representing the tracer short-circuit to thecelltailings, estimated from the (1 - α) parameter; the rest of the curve was ...
Get PriceJan 01, 2019· In the collision and adhesion phases of foamflotation, particles and bubbles are close to each other, driven by hydrodynamics, as illustrated in Fig. 2 using microalgalcellsas an example. When thecellencounters a rising bubble and traverses the different zones around the bubble [], the liquid films around thecellsand bubbles are compressed, thinned and ruptured, and thecellbecomes ...
