Avaliação econômica da aplicação da técnica de osmose reversa para reúso da purga de torres de resfriamento

Abstract

Currently, the environmental concern related to the uncontrolled consumption of fresh water, a finite natural resource, has led many industries to search for innovations and alternatives aimed at sustainability and maximum operational efficiency. In some places, the concentration of fresh water is low, which entails the need to resort to different processes to increase access to this natural resource. Based on this, an evaluation plan was prepared for the reuse project of blowdown water from cooling towers in industries, with a tool for manipulating process data and costs associated with the operation of the plant, specifically to verify the feasibility of implementation of reverse osmosis equipment. This method of water desalination is common in beverage industries, in places that are scarce and where it is necessary to collect sea water to make it drinkable. This project may help to reduce dependence on such a limited resource, being able to provide mechanisms for economic evaluation and reduction of fresh water. Furthermore, with the elaboration of an instructive booklet, it is believed that different industrial poles that use cooling towers can use the developed tools to increase water reuse resources and meet some of the sustainable development objectives proposed by the Nations United.
