Incremento de la productividad del proceso de tratamiento de lixiviados del relleno sanitario del Distrito Metropolitano de Quito mediante metodología DMAMC

Abstract

The main objective of the present work is to increase the productivity of the leachate treatment process with the physical treatment plant of Quito´s Landfill, using the DMAIC methodology (define-measure-analyze-improve-control). In the Define phase, the requirements and important characteristics for the client were identified, the reprocessed volume was analyzed, the Pareto chart and the project framework were made. In the Measure phase, random samples, control charts and process capacity analysis were carried out for different parameters. Also, the study of repeatability and reproducibility was performed. In the Analyze phase, hypothesis tests were realized. In the Improvement phase, a cost analysis and design of experiments DOE were implemented. In the Control phase, the process management and the response plan to be implemented when a discrepancy occurs in the treatment process were executed. Finally, cost analysis was accomplish considering the leachate treatment system with the physical treatment plant, the improvement of the treatment system, the control implemented in the leachate laboratory and the administrative costs. The productivity of the leachate system was calculated.
