Wetland projects developed in Brazil
The first studies with constructed wetlands undertaken in Brazil were the result of observations made from the Amazon flood plains. The first attempt to use this capacity to change the quality of the water, in the sense ...
Treatment efficiency of effluent prawn culture by wetland with floating aquatic macrophytes arranged in series
(Int Inst Ecology, 2014-11-01)
The efficiency of a series of wetland colonized with Eichhornia crassipes and Salvinia molesta to treat the effluent of a giant river prawn (Macrobrachium rosenbergii) broodstock pond was evaluated in this study. The ...
Constructed wetland-microbial fuel cells for sustainable greywater treatment
(MDPI AG, 2018)
Greywater reuse through decentralized and low-cost treatment systems emerges as an opportunity to tackle the existing demand for water. In recent years, constructed wetlands (CW) systems and microbial fuel cells (MFCs) ...
Use of the HDS system (hydric depuration with soils) associated to other constructed wetlands techniques for public water supply
Two projects of water treatment for public water supply were developed and operated by using combined systems of constructed wetlands. One of the projects was carried out in the town of Analandia, Sao Paulo, Brazil and ...
Análise de econometria de dois sistemas naturais de tratamento de água residuária na suinocultura
The aim of this work was to develop a detailed econometric analysis to compare a constructed wetland system - combined model, and a waste stabilization pond system - facultative pond, as a function of six different sizes ...
Determinação do coeficiente de decaimento bacteriano em wetland - alagado construído
(Universidade Federal do Rio Grande do NorteBRUFRNPrograma de Pós-graduação em Engenharia SanitáriaSaneamento Ambiental; Meio Ambiente; Recursos Hídricos e Hidráulica, 2011-09-22)
Wetlands systems are considered nowadays as a treatment method that uses simple, easy operation and low cost technology, which has been used in various parts of the world and also in Brazil. Used alone or as a complement ...
