General conclusion
At the end of this work, I would like to remind that my study falls within the general
framework of sustainable development and environmental protection. We
Microalgae are photosynthetic micro-organisms with a wide morphological diversity and
interesting biochemical characteristics, giving them a variety of scientific and industrial
applications in various fields: the production of high-value-added molecules used in
pharmaceuticals and cosmetics, human and animal nutrition, renewable energy production and
wastewater treatment.
In order to demonstrate the role of microalgae in wastewater treatment, We suggest
to apply this microorganismes to the design of the future wastewater treatment plant of the
municipality of Taoura, as this project aims to design a microalgae treatment plant, given that
the water discharged is biodegradable This choice of variants has been made with a view to
horizon 2050.
Based on our calculations made in this thesis, we can conclude that the proposed treatment
method is a promising and feasible one, and that the land reserved for the wastewater treatment
plant has the required characteristics, with sufficient surface area to accommodate the various
structures of which it is composed for the requested horizon (2050). However this methode can
be inhibited in winter due to changes in several parameters such as the drop in temperature,
therefor i suggest the use of greenhouses to be able to control the growth parametrers of
microalgae.
The valorization of the microalgae biomass produced and the reuse of purified water
are the two other perspectives from which the region's farmers could benefit.
However, despite its advantages, wastewater treatment using microalgae also presents
challenges and limitations. Large-scale implementation of this technology requires significant
investment in terms of infrastructure, equipment and technical knowledge. Further research
and development efforts are needed to overcome technical, economic and regulatory obstacles
and enable more widespread adoption of this technology.
