The results allow us to identify the 4% NaCl concentration as the best for the preparation of the coagulant from LL, given that with this concentration the highest turbidity removal of 81.3% was achieved using a dose of 4.5 mL/L. Figure 1b shows that the concentration of NaCl does not have a significant effect on the pH of the water, as occurs in experiments carried out with natural coagulants by Carrizales Condori & Enríquez Nateros (2019).	cache/cet-15450.pdf	txt/cet-15450.txt
