Proposta de reuso da água utilizada no pré-preparo de hortifrutigranjeiros e na higienização de pratos e talheres em um restaurante universitário no Estado do Rio de Janeiro
Abstract
Objective: The aim of the present study was to propose the reuse of water in a university restaurant in the state of Rio de Janeiro, as well as measures to reduce consumption. Methods: A form was applied to quantify water consumption during the pre-preparation of fresh produce and the sanitization of dishes and flatware, within a period of 9 and 13 days, respectively. Later, the volume of potable water used daily was estimated in liters. Results: The estimated volume of water used per day was 2.400 liters for pre-preparation of fresh produce and 478 liters of water per day for sanitization of dishes and flatware. Thus, a total volume of 2.878 liters of water per day for non-potable reuse was estimated, such as, for example, for the sanitization of the dining hall floor of the restaurant. In addition, the quantification of water points for possible installation of faucet aerators was made aiming to reduce consumption. Next, a project of the storage container for the reuse of water was developed. Conclusion: It may be concluded that the importance of the proposal is related to the significant quantity of daily wasted water that could be reused and thus, contribute to environmental preservation and decrease the water expenses of the university restaurant.
