Laboratory analytical results remain very promising. We have filtered BOD values of 3 mg/l, the absence of fats and pathogenic bacteria, and high concentrations of chlorophyll "a" product of Spirulina that grows naturally in our treatment bowls. It is worth noting the importance of the cultivation of microalgae in ecosystems since they act as biological filters capturing CO2 emissions into the atmosphere. In this way, we contribute to the mitigation of emissions of this greenhouse gas.
