Biorremediación de agua residual de la industria textil por medio de chlorella vulgaris

The textile industry often utilizes dyes containing pollutants that cause irreparable damage to the environment and may have adverse effects onhuman health when discharged into water sources or soils. Therefore, it is essential to explore environmentally friendly alternatives, such asthe latest technologies involving microalgae. In this study, microalgae technology, specifically Chlorella vulgaris was utilized at a laboratory scalefor the bioremediation of wastewater from the textile industry. The culture conditions included a pH range of 7-8, a temperature between 17 °C and 20 °Cwith constant agitation, and a supply of red LED light. In the bioremediation process, three samples were used, each with its respective replicates, atconcentrations of 50%, 25%, and 12.5% by volume of wastewater, with an initial volume of 200 mL of microalgae for each. Results indicated bioremediation percentages exceeding 95%. Notably, it was observed that lower wastewater percentages correlated with higher bioremediation percentages. This observation suggests a potential relationship between concentration and efficacy. Considering the promising results, we propose a basic design for scaling up this process to an industrial level. This involves identifying the most suitable equipment and conducting corresponding calculations to optimize the efficiency of the bioremediation process.
