Flotation in a novel oscillatory baffled column

Liquid culture of microalgae in a photobioreactor (PBR) based on oscillatory baffled reactor (OBR) technology – A feasibility study

“…This result is not surprising given previous studies that demonstrate OBR technology for use as a flotation device (Anderson et al, 2009) and the design of foam flotation systems (Coward et al, 2013).…”

Biological processing in oscillatory baffled reactors: operation, advantages and potential

“…Generates increased particle flotation [33,34] increased mass transfer uniform bubble size and increased gas hold up produce enhanced mass transfer rates sixfold and 75% increases for oxygen transfer (k L a) into water and yeast culture, respectively [28,35] compact reactor design the ability to generate long residence times, under plug flow, with reduced reactor lengths allows compact designs up to a 600-fold decrease in reactor length compared with conventional tubular reactors [36] linear scale-up maintaining St, Re o and Re n allows mixing intensity and flow conditions to be predicted in large volume OBRs using data from laboratory-scale experiments laboratory-scale experiments can be scaled up by increasing OBR diameter or length while maintaining predictability [29,37,38] rsfs.royalsocietypublishing.org Interface Focus 3: 20120036…”

“…Typical chemical processes can take anywhere from fractions of a second to many hours in a conventional reactor. The process advantages of OBRs have been investigated and described for a range of applications including biofuel production [55,56], flotation [34], butylation of phenylacetonitrile [57], oil droplet breakage [58][59][60], photo-oxidation [61,62], polymerization [63] and extensive work on crystallization [64 -71]. However, this review aims to target bioprocesses; so chemical reactions will not be discussed in any further detail.…”

Review of Reducing Entrainment of High Ash Fine Slime to Concentrate in Flotation Process

“…FJG-S8 oscillating flotation machine used in Xuzhou Jiahe coal preparation plant showed that the ash content of concentrate reduced by 1.42% compared with of mechanical agitation type flotation machine before the transformation under the feed with 39.18% ash content and 68.13% content of -0.045 mm size fraction [24]. Oscillatory baffled column (OBC) was developed by assembling vibration force field to flotation column [25]. Even distribution of pulp flow field in column and strengthening of effective particle-bubble contacting reduced the entrainment of fine gangue to concentration.…”
