The objective of the study was to evaluate the efficiency of a laundry wastewater treatment system at the laboratory level, where an organic polymer was used as a coagulant-floculant that manages to decrease pH, COD, TSS and temperature concentrations, to the extent that they meet the Maximum Allowable Values (VMAs). To do this, the laundry wastewater was first characterized for 8 hours. Then the test was carried out in test tubes, with 10ml of waste water, to choose the best polymer. Four were used (Chitosan, Tanfloc, Flopam and Moringa) and, they were evaluated at three pH levels (6, 8 and 10 approx.), seven turbidity levels (189 to 500 NTU), in 10 seconds of mixing and necessary settling time. Tanfloc was chosen among the four, as it was needed at a lower dosis (from 8mg/L to 160mg/L), achieved greater removal (turbidity up to 98% and pH within the limits) and better sedimentation speed (5 minutes). The second test was in bottles, where they were put in five bottles, 1 liter of waste water and the necessary Tanfloc. The mixing time (bubble from 30s to 150s) and settling time (20min to 60min) was analyzed. The reduction results were: COD (63.3%), TSS (85.88%); in 120 seconds of mixing and at least 20 minutes for sedimentation. The third step was to design and build a laundry wastewater treatment system at the laboratory level. To do this it was divided into three zones: Equalization, Coagulation-Flocculation and Sedimentation. The last step was to evaluate this treatment system. Reduction results were: COD (60.76% to 85.6%), TSS (82.54% to 96.44%) pH (4.8% to 18.8%). The conclusion is that the treated water coming out of the treatment system complies with the VMAs except Temperature.
