This research sought to determine the ideal percentage of soaking water from the tannery industry as a nutrient source for the microalgae Chlorella sp.; evaluating the effect of the initial concentration of 15, 30, 45, 60 and 75% of soaking water in contact with the microalgae in a first phase and a new evaluation with 30, 45 and 60% of soaking water using the adapted microalgae from the first phase into the second. Cell density over time was determined by cell counting in a neubauer chamber until reaching the stationary phase in all samples. The results show that the microalgae adapted to the effluent used present growth kinetics more similar to that of microalgae grown in a conventional medium. In the same way, it was determined that a better cell growth was obtained with a 30% concentration of soaking water. It is concluded that the use of soaking water is an efficient way to cultivate microalgae, thus helping to reduce pollution from tannery effluents.
