RESUMO:

The water crisis is now a real problem reaching millions of people and has placed water as the center of great discussions and conflicts around the world and, it is well known the growing concern for the preservation of this resource that is essential for the emergence of life and especially maintenance of her. A United Nations (UN) report published in march 2015 states that if nothing is done, the world's water reserves can be reduced by 40 percent by 2030 as a result of the urgent need to improve the management of this resource to ensure supply to the world's population. In hemodialysis, water plays a key role because it is through the reverse osmosis treatment process that the degree of purity required for dialysis is achieved, however, this process wastes a lot of water, generating unnecessary expenses and damages to the environment. This study is a descriptive research of a quantitative approach whose main objective was to verify the viability of the reuse of the water rejected by the reverse osmosis treatment process in the hemodialysis sector of the Onofre Lopes-Natal-RN University Hospital and for that purpose It is necessary to measure the amount of water discarded in a period of 30 days and to perform the physical-chemical and microbiological analysis of this water to confirm the practicability of the reuse. It was verified that the average of the discarded waste volume was 910, 4 liters per day and the results of the analyzes of the water, from the microbiological point of view as well as physico-chemical, were satisfactory for classification of the water in several procedures of reuse, meeting perfectly the four classes suggested by NBR 13969/97. The results of the study will certainly be useful to assist hospital management with regard to the sustainable use of water resources, as well as their better reutilization and will also serve as a stimulus and database for future research.
