Aplicação da metodologia PDCA para redução de custos com produtos químicos em uma estação de tratamento de efluentes industriais alimentícios

Abstract

Wastewater treatment in industries is crucial not just thinking about sustainability, but also to meet legal requirements. Due to the large water consumption in production processes, industrial wastewater treatment plants usually have considerable proportions and consequently high costs of operation. An appropriate management in a treatment plant makes that resources are efficiently used, on the other hand if the expenses are not monitored difficulties may occur with the available budget. In a scenario variable costs, it is proposed the application of the PDCA methodology to perform cost management with chemicals in a wastewater treatment plant from slaughterhouses of chicken, pigs and dairying. The planning stage of PDCA was drafted considering data from the cost of the chemicals used in this season between January to June 2018. It was used quality tools to identify and prioritize the issues and causes, as well as propose solutions to reduce the cost of these inputs. The actions were carried out from July to September of the same year and in October was carried out the verification of the results. With the check it was found that the result of the actions proposed in the planning stage of this PDCA were not effective to reduce costs with chemicals. Being proposed in the last step of PDCA alternatives to redo the cycle whereas aspects that had not been previously observed in the planning or that occurred following the execution of this.
