A DEWATS (decentralized wastewater treatment system) is an alternative for expanding sanitation. In Brazil, DEWATS is acknowledged by law and is part of the National Sanitation Plan strategy for achieving the treatment of 85.6% of all the generated wastewater by 2033, improving the current treatment index of 49%. This review's aim is to identify DEWATS studies in Brazil and to verify their potential for narrowing the national wastewater treatment deficit. Hence, aspects such as cost, maintenance, and efficiency were assessed. The archival research method (ARM) was used to identify papers published in the last 20 years through the scientific databases of Scopus, Science Direct, and Web of Science. Data regarding the general characteristics of each study were collected and compared to Brazilian environmental regulation and sanitation status. The results showed the evaluation of different technologies as DEWATS, highlighting their flexibility and potential use in 79% of Brazilian counties. However, although 81% of the studies conducted performance analysis, none covered the main parameters required by Brazilian law. Although legal gaps for DEWATS improvement and consolidation have been identified and the interest in studying DEWATS has been increasing in the last five years, many barriers to their widespread use remain.
A Engenharia Ambiental, ainda recente quanto a alunos egressos, está segmentada em formações específicas com ênfases em Sanitária, Energias Renováveis e Urbana. Este artigo tem por objetivo apresentar o conteúdo do Ensino de Química na Engenharia Ambiental e Sanitária do Centro Universitário Senac, o qual potencializa os conhecimentos prévios das disciplinas do núcleo específico do curso. A metodologia adotada foi a qualitativa de estudo de caso e teve, a priori, um levantamento do estado da arte de quantidade de instituições que oferecem esses cursos.
