Proposta de dimensionamento e implantação de wetlands construídos em sistema individual de tratamento de esgoto sanitário
(Universidade Tecnológica Federal do ParanáCuritibaBrasilDepartamento Acadêmico de Química e BiologiaTecnologia em Processos AmbientaisUTFPR, 2015-07-03)
The situation in Brazil, regarding to pollution of rivers and public fountainheads, offers the population poor sanitation conditions. This is common in rural areas or those in urban sprawl where there is still no distribution ...
Application of double filtration with granular activated carbon for Atrazine reduction on water treatment processes
(Universidad Nacional de Colombia - Sede Medellín - Facultad de Minas, 2018-04-01)
Atrazine is one of the most often used herbicides in the world. It reaches the surface water body by runoff, direct application or airborne dispersal. Conventional water treatment methods do not efficiently remove these ...
Synthesis and characterization of adsorbents for the elimination of nitrates and bromates from water aiming to develop a continuous oxyanion water elimination system
(IWA Publishing, 2021-05-01)
It is known that the excess of oxyanions such as NO 3 and BrO 3 in drinking water affects its quality. In this work, three adsorbents (montmorillonite (Mt), silica (Si), and diatomaceous earth) loaded with hexadecyl- (H) ...
