Microbial indicators of soil health as tools for ecological risk assessment of a metal contaminated site in Brazil
(2012)
Microbial and biochemical indicators of soil health were used to assess the ecological conditions and biological activity of soils contaminated with metals at a lead smelter plant and surrounding area in northeast Brazil. ...
Nitrifying niche differentiation in biofilms from full-scale chloraminated drinking water distribution system
(Pergamon-Elsevier Science Ltd, 2020-06-01)
Tropical conditions favor the auto-decomposition of monochloramine (MCA) leading to disinfectant decay and free ammonia in drinking water distribution systems (DWDS); thus, they promote the growth of nitrifiers and the ...
Avaliação de sistema de lodo ativado híbrido empregado no póstratamento de reator UASB em região de clima quente
(BrasilUFRNPROGRAMA DE PÓS-GRADUAÇÃO EM ENGENHARIA SANITÁRIA E AMBIENTAL, 2019-04-16)
One of the most widely used technologies for the biological treatment of domestic and industrial
wastewater is the activated sludge process (LA), due mainly to high effluent quality and reduced
area requirements. Among ...
Maize-Brachiaria intercropping: A strategy to supply recycled N to maize and reduce soil N2O emissions?
(2021-10-01)
Nitrogen use in agriculture directly impacts food security, global warming, and environmental degradation. Forage grasses intercropped with maize produce feed for animals and or mulch for no-till systems. Forage grasses ...
Tratamento de lixiviado de aterro sanitário utilizando contactor biológico rotatório visando a remoção de nitrogênio amoniacal
(Universidade do Vale do Rio dos Sinos, 2013-12-20)
This research proposes the use of a rotating biological contactor (CBR) with 4 stages in the treatment of landfill leachate seeking the removal of organic matter and ammonia nitrogen. To help nitrification of ammonium ...
