Reutilização de água residual no processo de gestão de lava jato: um estudo multicaso

Abstract

Introduction: Efficient and effective management by means of alternatives of reuse of water in lava jets besides being part of a promising environmental management is also a factor of competitiveness through the economy in the account of monthly water consumption. Planetary water resources are of concern to scientists, environmentalists and rulers as environmental pollution and devastation begin to undergo contingent, unforeseen and more intense behavior and mechanisms based on data known and recorded over a century. Increasingly the media are reporting on regions suffering from water scarcity. The consumption of drinking water or treated in lava jets is a variable that characterizes the need to better understand and use this important and vital natural resource. Objective: general: to examine the environmental issue related to the importance of water for human existence and the way water is managed in car wash stations. Specific: to analyze the value of water use in a rational way, to reduce its waste and to minimize the generation of effluents; to verify the environmental problems related to the process of water use, its treatment and reuse in car wash stations (jet washes); to evaluate environmentally more efficient and effective alternatives for the reuse of water in car wash services; to carry out a diagnosis of the water consumption in the car wash stations located in the housing complexes: Santos Dumont, Hiléia I and Hiléia II. Methodology: Inductive and observational research was carried out in three (3) sets located in the Center-West Zone of Manaus: Santos Dumont Complex, Hiléia I Complex, and Hiléia II Complex. Results: Lava jets 1 and 5 were almost at the same level of consumption; the same was true for car wash stations 2 and 3. PLA 3 spent more water than PLA 1 because of the difference in task execution method. Wash stations 1 and 2 use a bucket with shampoo, water and sponge, in the third procedure. After this procedure the rinse is done. In PLA 1, the two processes are performed concomitantly (shampoo and rinse). In the survey carried out in the 5 washes, there was not only a huge waste of water during the services, but also the bleeding of huge amounts of detergents, greases and oils. Final considerations: In the companies visited, it was verified that there is no work management, there is no technical guidance regarding the material used, nor sensitivity to environmental issues. This fact generates waste. Therefore, there is a lack of sensitivity and respect for the environment, since there are methods and tools available in the market for politically and environmentally correct business attitudes in this market, such as the implementation of the environmental management tool called 3R's and the gravimetric separator.
