PHOTOBIOREACTORS

PHOTOBIOREACTORS



Algae can be harvested using a device called photobioreactors, this is also known as a PBR.  The PBD is  a self contained system with a controllable environment.

 It allows the  the supply of light, nutrients, carbon dioxide, air, and temperature can be regulated. Using a PBR ncan prevent or at least minimise contamination (from other algae species and bugs), and allows easier cultivation of one algae strain. It also offers better control over a range of other growing conditions.


  In addititon to this a, closed system such as the PBR reduces evaporative water losses, and has lower carbon dioxide losses which all-in-all means higher cell concentrations. In other words there are more grams of algae produced per litre of water.
