Large-scale productions of microalgae are limited by contamination and strain compatibility issues. The effectiveness of large-scale systems is directly related to the type of wastewater used. Technical challenges exist in scaling up microalgal production from controlled laboratory conditions to industrial environments.

Further research is needed to scale up microalgal production and address contamination and strain compatibility issues. The potential of microalgae for nutrient recycling, wastewater valorization, and carbon sequestration should be explored further. The use of microalgae in combination with other sustainable practices should be investigated.
