The present document shows the growth of microalgae in a controlled environment of commercial fertilizers for their possible incorporation in a wastewater treatment plant. It shows the growth of two strains of microalgae evaluated with two fertilizers for plants to assess which microalgae adapted best to the stablished condition. The strain of microalgae from the lake, which was identified morphologically as a mixture that contained mainly Nannochloropsis, performed best. The algae growth was evaluated between 5 and 10 days, depending on the assessed experimental stage. During this period the turbidity, the absorbance and the total suspended solids were measured, showing exponential growth. A correlation was made with the data between turbidity vs TSS to estimate future TSS values based on turbidity measurements. Finally, it was evaluated the performance of the isolated microalgae strain to wastewater from a local WWTP, before and after the secondary treatment, and after the treatment with added fertilizer. The highest removal percentage was obtained with the post-treatment wastewater.
