| Summary: | The discharge of municipal wastewater into local water bodies is one of the main causes of eutrophication. As a tertiary treatment for this problem, a culture of Chlorella sp. (recognized for its ability to remove phosphates and nitrates in wastewater) was used in a vertical system of photobioreactors with a bubble column at a pilot scale. An experimental factorial design was carried out, with three experimental phases, was used municipal wastewater from the WWTP “El Pueblo”. Initially, the inoculum size was determined at which the highest removal of NO3- and PO43- is obtained, was resulted as optimal cell density 3.6x106 cel/mL. The second phase allowed quantifying the concentration of phosphates and nitrates removed from wastewater evaluated according with the growth of the strain used, the experiment yielded removals greater than 95% in nitrate concentrations and 65.5% for phosphates. In the third phase, the inoculum size determined in first phase, was taken to a photobioreactor system evaluating its operating parameters regarding the nutrient removal capacity of the strain. With the results obtained, it was concluded that the proposed system is a viable alternative for the treatment of wastewater with different nutrient loads. |
