Therefor :
Ld = √2 × í µí± í µí±
The teriary treatment calculation results are listed in the table 23(Chapter 3).
6.5.4. Storage basin
For the reuse of treated water, we propose a rectangular open-air storage basin with
a volume of : 300m
3 .
Sizing the storage basin
Calculation of storage basin surface area (SS)
We have :
í µí±º í µí±º =
í µí±½ í µí±º
í µí±¯
With :
SS: surface area of storage basin.
H: Height of storage basin (we propose that: H = 1.5 m).
VS: storage basin volume (We propose that : VS= 300m
3 ).
Calculation of the lenght (LS) and the width (WS) of the
storage basin
We propose that the lenght of the storage basin: LS= 16m.
Therefor:
WS =
í µí±º í µí±º
í µí° í µí±º
The storage basin calculation results are listed in the table 24 (Chapter 3).
6.5.4. Microalgal biomass treatment unit
After a wastewater treatment cycle, the microalgae biomass used during the
secondary treatment will be harvested and sent to a unit to follow a processing chain in order
to extract and concentrate the valuable compouunds for various applications, this unit is
called: microalgal biomass treatment unit. We propose a surface area of 130m
2 .
The processing steps at this unit and the machines used are summarized in the table
25( Chapter 3).
