Thriving in salty environments: aspergillus niger's halotolerance and BTEX biod...
Rodrigues, Kelly; Salgado, Ricardo; Galhanas, Dina; Bermudez, Victoria Maura S.; Silva, Glória Maria Marinho; Mata, Ana Maria Álvares Tavares daBenzene, toluene, ethylbenzene, and xylene (BTEX) can be found in marine and estuarine waters due to accidental spills of oil and derivatives, as well as in production water and effluents discharged from petrochemical plants. Addressing the bioremediation of these compounds in saline environments and effluents with elevated salinity levels is imperative. In this study, the halotolerance of Aspergillus niger was...
Wastewater matrix effect on disinfection with lp/uv and mp/uv radiation
Salgado, Ricardo; Hipólito, Cláudia; Galhanas, Dina; Epifâneo, Lisete; Noronha, João PauloThe disinfection of the wastewater effluents is important to reduce the pathogenic microorganism impact in the environment. UV radiation is one of the technologies used for this purposed. The wastewater characteristics, such as dissolved organic compounds or the presence of suspended solids can affect the efficiency of the faecal coliform bacteria removal in the disinfection process by ultraviolet (UV) radiatio...
Photolysis, ozonation and chlorination of flame retardants in water treatment
Salgado, Ricardo; Chanfana, Cátia; Martins, Susana; Galhanas, Dina; Epifâneo, Lisete; Noronha, João PauloFlame retardants (FR) are added to different materials to reduce the risk of fire. They save lives, prevent injuries and property losses, and protect the environment by helping to prevent fires. In Western Europe, the average annual growth rate for 2007–2012 for all flame retardant chemicals is expected to be just over 3% in volume terms. The benefits of flame retardants must necessarily be balanced with the ri...
