Abstract(s)
As águas oleosas contaminadas são uma fonte
de poluição gerada por várias indústrias. São
constituídas por uma fase aquosa e uma oleosa,
contendo ainda outros poluentes provenientes
tanto dos processos produtivos, como
naturalmente associados aos óleos constituintes.
Esses efluentes têm um elevado impacto sobre
a qualidade dos recursos hídricos, da vida
aquática, do ar, do solo e da saúde humana. É
por isso essencial o seu devido tratamento. Os
estudos de investigação focam-se normalmente
na recuperação da fase aquosa, embora a fase
oleosa possua, não raras vezes, um elevado valor
acrescentado que justifica o seu tratamento e
recuperação. Os tratamentos tradicionais, como
os processos físico-químicos ou biológicos, são
normalmente ineficientes para o seu tratamento.
Os processos avançados de oxidação (Advanced
Oxidation Processes, AOPs) são uma alternativa
viável para o tratamento adequado de águas
e eliminar poluentes das fases orgânicas de
interesse com o objetivo da sua recuperação.
Contaminated oily wastewaters are a source of pollution generated by different industries. They consist of an aqueous and an oily phase, containing several other pollutants, whether they come from the production processes or are naturally associated with the constituent oils. These wastewaters have a high impact on the quality of water resources, aquatic life, air, soil, and human health. Therefore, their proper treatment is essential. Research studies are typically focused on recovering the aqueous phase, although the oil phase often has a high added value that justifies its treatment and recovery. Traditional treatments, such as physical-chemical processes or biological, are usually inefficient in their treatment. Advanced Oxidation Processes (AOPs) appear as an alternative capable of adequately treating water and eliminating pollutants from organic phases of interest to recover them.
