Abstract

Microalgas, tratamiento, aguas residuales, curtiembre Abstract The wastewater from the tanning industry has high concentrations of heavy metals, especially chromium (Cr), as well as other components such as Nitrites, Nitrates, Phosphates, and sulfates, which, if not treated prior to discharge, can seriously alter the quality of surface water bodies. [...]an alternative treatment to these industrial effluents has been proposed in various investigations. Scenedesmus sp, Spirulina sp, Chlorella sp, Tetraselmis sp, and Pseudochlorella sp., Important for their high efficiency in removing Chromium, and others polluting elements; where, the genus Scenedesmus and Spirulina demonstrated an efficiency greater than 85% of Cr removal, followed by Chlorella and Pseudochlorella (> 60%). In the removal of nitrates and nitrites, the genus Scenedesmus, showed better levels of removal (90%), followed by Chlorella and Pseudochlorella (65%). Regarding the removal of Phostates and Sulfates, the genera Chlorella and Pseudochlorella were the type of algae that showed a removal level of 100%, followed by Tetraselmis, Scenedesmus and Tetraselmis (> 95%).
