The present study aimed to evaluate the mucilage extracted from the cladodes of yellow pitahaya (Cereus triangularis haw) as a natural flocculant in the treatment of wastewater from car washing, the type of methodology that was implemented was experimental, where data were collected in the field and in the laboratory, the pitahaya mucilage was obtained after going through a cleaning of the cladodes, debarking, crushed and macerated. The tests were carried out in the Chemistry laboratory of the Pontificia Universidad Católica del Ecuador Sede Ibarra, for which residual water from a car washing machine was used. The comparative tests developed at the beginning between different doses of mucilage and wastewater, define the process and the applicable doses of pitahaya mucilage, resulting in a volumetric ratio of Mucilage - Water. The tests carried out using the Jarras method, which demonstrated the efficiency of pitahaya mucilage in the process of removing suspended particles from wastewater, indicated that the reduce (94%) turbidity, (69%) total dissolved solids and the (93%) of color, these values were compared with a commercial flocculant (FLOC). Based on the results obtained, it can be concluded that the fresh mucilage of pitahaya cladodes significantly affects the removal of suspended particles and the flocculant can be used as a vision of a sustainable alternative. |
