Aerators for algae cultivation : Characteristics 1I read two very important blogs in oilgae site.They are about Aerators.One is about Characteristics of major Aerators.The article concludes as "The aeration rate must be carefully balanced to achieve good mixing, liquid circulation and mass transfer while avoiding shear stress to the algal cells grown in a photobioreactor. Aeration must ensure the oxygen generated by photo-synthesis is removed; otherwise, it can inhibit cell growth. Thus, the above details about the design and operation of aerator systems stress the crucial role of aeration in algal cultivation using photobioreactor. "The url for that article is http://www.oilgae.com/blog/2010/09/characteristics-of-major-aerators.html
The second article is about What is aeration in a Photobioreactor
Aeration of cultures serves to keep algae in suspension, to supply the carbon needed for plant growth and pH control, and to strip O2 from the culture media, preventing supersaturation.The url ishttp://www.oilgae.com/blog/2010/09/aeration-in-a-photobioreactor.html
May be you would like to read the second one first and vice versa.
