The systematic classification of spirulina has been studied by several authors. Gardner (1917),
suggested the name Arthrospira for forms with visibly partitioned walls, and Spirulina for forms
with invisible partitions. Subsequently, Berguey (1994) classified them as follows:
Order : Nostocales
Family : Oscillatoriaceae
Genus : Spirulina
Specie : Spirulina platensis (Berguey, 1994).
The optimal conditions for growing Spirulina platensis are summarized in the following figure:
Figure 23: Spirulina platensis cultivation parameters (Razzak et al., 2017).
Mass load (Cm)
We have: 0,1 < Mc<0,5 Kg BOD5/Kg.VSS.d
The mass loading or loading factor expresses the ratio between the mass of pollutant
substrate and BOD5 entering daily and the mass of microalgae contained in the reactors.
It is expressed in KG/BOD5/ KG of dry matter per day.
The plant calculation will be based on the following Mc value:
We assume a mass loading: Cm = 0.3 Kg BOD5/ Kg VSS.d.
