What is it about?
The reduced dissemination of research carried out in Brazilian post-graduation studies (master's and doctorate levels) dealing with the use of constructed wetlands in wastewater treatment can be suggested as one of the causes of the limited use of this technology outside academic studies. The present paper aimed to synthesize information from research at the post-graduation level in Brazil on the use of constructed wetlands in wastewater treatment. Data from 253 dissertations and thesis (over 30 years) were collected throughout the Brazilian territory. Thus, some conclusions could be found, such as the observation that academic institutions in the south-southeast region were responsible for most of the production on that subject in the country. The plant species of the genus Typha spp and the gravel composed the vegetation and support media most used in those studies, respectively. The types of polluted water most adopted by those researchers were sewage from the university campus and urban sewage. The terminologies most used to indicate this wastewater treatment process was “wetlands construídas” and “alagados construídos” respectively. These treatment systems operated predominantly at the secondary and tertiary levels, evaluating mainly the removal of organic matter and nutrients from the studied waters.

Why is it important?
The reduced dissemination of data and information obtained in Brazilian postgraduate research results in the retention and low dissemination of knowledge related to the technology of constructed wetlands, which causes the reduction of their use beyond the reach of institutions of teaching and research. Many of the master's or doctoral research do not culminate in publications in journals or scientific events, which further limits the dissemination of the knowledge generated in these studies. In this context, the present work aimed to collect information about research of wetlands built for wastewater treatment in graduate school (dissertations master's and doctoral theses) in Brazil.
Perspectives
This paper has the power to conduct future research on constructed wetlands in Brazil in items not yet researched. As an expected final result, this paper can contribute to the improvement of constructed wetlands projects and to the dissemination in Brazil of this type of simple and low-cost treatment.
