Methodology

Introduction:
The treatment of wastewater is a major challenge in the field of sanitation, involving the
use of facilities known as wastewater treatment plants.
The introduction of microalgae in wastewater treatment opens the door to an innovative and
ecological approach to water purification. By combining the power of microalgae
photosynthesis with their ability to absorb nutrients and reduce pollution, this method offers a
promising solution to the growing challenges of wastewater management. This introduction
will explore the fundamentals of designing a wastewater treatment plant using microalgae,
highlighting the key stages and the resulting ecological benefits. The first step in sizing such a
plant is to choose the right location.
1. Presentation of the study area
The study area is located in the far north-east of algeria, on the Algerian-tunisian border.
it lies 140 km south-east of the city of annaba and 200 km east of constantine. The souk ahras
region lies in a transition zone between the tellian atlas and the saharan atlas. After a visit to the
Souk-Ahras state, I found a suitable site for a microalgae wastewater treatment plant in the
municipality of Taoura, that belongs to the southern souk-ahras mountains. Wastewater from
this municipality is currently discharged into water bodies without any prior treatment. This
practice is detrimental not only to public health and the surrounding environment, but also to
the region's water reserves. The construction of a wastewater treatment plant for this
agglomeration will not only protect the environment, but also will provide additional quantities
of quality water for irrigation.
The choice of site for the future Taoura WWTP is based on a compromise between the
following objectives and constraints:
Best environmental protection.
Possibility of reusing effluent for irrigation.
Budgetary constraints, especially in terms of investment and operation.
Non-flood zone.
Surface area.
Distance from town.
Prior to any hydraulic project, a site survey is necessary to understand the physical
characteristics of the site and the factors that can influence the design and success of a project.
