**2. Experimental**

The experimental protocol was proposed in three stages derived from taking a sample of the residual water generated in a fish packing company. In the first stage, the quality of the wastewater from the fish packing process was evaluated through

measurements of chemical oxygen demand (COD), total organic carbon (TOC), total nitrogen (TN), total phosphorus (TP), etc. In addition, the biodegradability of the contaminants contained in water was evaluated by means of a solid model. In the second stage, the coagulation-flocculation windows (ζ vs. pH) were determined and in the third part, the factors of pH, ζ and polyelectrolyte concentration were correlated in order to evaluate the organic matter separation process in the wastewater of the fish packing plant measuring turbidity, COD (Horiba Coda-500-A), COT (Hatch colorimetric measurement), TN (Hatch colorimetric measurement) and TP (NMX-AA-029-SCFI-2010).
