Kanel Jeffrey Scott, Guelcher Scott Arthur: Method for cross flow microfiltration of microalgae in the absence of flocculating agents. Eastman Chemical Company, sMARTIN Charles R, July 2, 1998: WO/1998/028403

A process for dewatering the alga $i(Dunaliella salina) in brine is disclosed for the recovery of mixed carotenoids. The algal cells are ruptured. The brine is pumped in the absence of any added flocculating agents across a microporous filtration membrane having an absolute rating of about 10 micron ...

Guelcher Scott Arthur, Kanel Jeffrey Scott: Method for deep bed filtration of microalgae. Eastman Chemical Company, MARTIN Charles R, July 2, 1998: WO/1998/028404

A method for deep bed filtration of microalgae in aqueous suspension for the purpose of dewatering the algae is disclosed. The cells are ruptured prior to filtration. The aqueous suspension is then contacted with the deep bed filtration media and collected in the media. The algae may be recovered fr ...

Kanel Jeffrey Scott, Guelcher Scott Arthur: Method for rupturing microalgae cells. Eastman Chemical Company, sMARTIN Charles R, July 2, 1998: WO/1998/028407

A method for rupturing microalgae in an aqueous suspension is disclosed. In one embodiment the aqueous suspension is passed through a constriction into a liquid phase at a pressure sufficient to rupture the cells by circulating the aqueous suspension through a constriction in a pump loop at a pressu ...

Guelcher Scott Arthur, Kanel Jeffrey Scott: Method for dewatering microalgae with a bubble column. Eastman Chemical Company, sMARTIN Charles R, July 2, 1998: WO/1998/028081

A process for dewatering an aqueous suspension of microalgae is disclosed in which the aqueous suspension of the algae is introduced into a bubble column or a modified bubble column for generating a froth of bubbles and adsorbed algal cells that can be separated from the aqueous suspension. In one a ...

Kanel Jeffrey Scott, Guelcher Scott Arthur: Flotation separation methods and systems for dewatering suspensions of microalgae and extracting components therefrom. Eastman Chemical Company, MARTIN Charles R, July 2, 1998: WO/1998/028082

A process and system are disclosed for recovering mixed carotenoids from the alga $i(Dunaliella salina). The harvested cells are ruptured, typically by circulating the algal suspension at high pressure through a pump loop. The cells can then be dewatered by absorptive bubble separation techniques, i ...

Guelcher Scott Arthur, Kanel Jeffrey Scott: Methods for dewatering microalgae with a jameson flotation cell. Eastman Chemical Company, MARTIN Charles R, July 2, 1998: WO/1998/028083

Methods are disclosed for dewatering an aqueous suspension of microalgae, especially $i(Dunaliella salina), with a Jameson cell. The algal cells are ruptured sufficiently to promote froth flotation of the cells from the suspension. The algal suspension is introduced into the top of the Jameson cell ...
