Métodos e técnicas de tratamento de águas de abastecimento para consumo humano: uma visão prospectiva

Abstract

The treatment of supply water is intended to make the water drinkable by correcting some characteristics that may make it outside the established standards for consumption. Faced with the need for this treatment, the development of improved and innovative techniques arises to supply the water supply in the face of the necessary parameters. In order to define a water treatment technology to be implemented, aspects of the water to be treated must be analyzed, complying with the quality criteria defined by national and international standards, in addition to the costs involved and the reliability of the method. Thus, scientific and technological prospection emerges as research tools aiming to compare information and analyze the proposals already used, which can be used to study new technologies for the treatment of water supply, intending to find strategies and new alternatives, with the intention of promoting the efficient use of water in different environments. Based on this, a scientific prospection of the theme was carried out, aiming to identify the titles related to the treatment of water supply in the Scopus bases (Elsevier) and in the Digital Library of Theses and Dissertations (BDTD), after the research, the bibliometry was presented according to with the year, institutions, document type and geographic regions. In this way, the technological prospection was also carried out at the National Institute of Industrial Property - INPI, addressing the most relevant technologies to the subject, found in the bibliographic prospection, and through the technological portfolio produced, a ranking of these technologies was made according to grades granted through to the content presented on the patents in each filing.
