Descarte da água de rejeito gerada pela osmose reversa em uma clínica de hemodiálise no município de Salvador-Ba

Abstract

The main treatment for Chronic Kidney Disease in Brazil is hemodialysis, for which it is necessary to use purified water, patients undergoing hemodialysis are submitted to weekly treatment of 3 sessions with an average duration of four hours, and for each session a volume of approximately 120 liters of water is required. In obtaining treated water using reverse osmosis equipment, on average 1/3 of the water entering the system is discarded as saline (waste water). The reuse of the concentrate generated by reverse osmosis treatment in the dialysis clinics can favor a significant financial saving, however, more relevant than the financial economy, can represent the economy in the spending of the natural resources. In view of this, this work seeks to study the volume and fate given to waste water - also called concentrate, generated during the treatment of water for hemodialysis by reverse osmosis, in a dialysis center within a hospital institution in the city of Salvador- BA. The present study is a descriptive case study, with a quantitative approach of an applied nature, of the non-participating observational type, with the purpose of describing and characterizing the information collected regarding the number of dialyzed patients in a clinic, assessing the volume of waste water is produced by each treatment and describes the technique used to discard this water. After investigating and counting the total volume of reject water generated by Reverse Osmosis, it was identified that there is no reuse of waste water, the final product of the reverse osmosis process of the clinic in question, as a product of the work, given one of the objectives of the study was elaborated a proposal in the format of a Technical Note directed to DIVISA (Division of Sanitary Surveillance), the Technical Note proposed as a result of this work aims to bring light and awareness about the need to reuse wastewater in clinics.
