  • A two-step approach for copper and nickel extracting and recovering by emulsion liquid membrane

    The recycling of copper and nickel from metallurgical wastewater using emulsion liquid membrane (ELM) was studied. P507 (2-ethylhexyl phosphonic acid-2-ethylhexyl ester) and TBP (tributyl phosphate) were used as carriers for the extraction of copper and nickel by ELMs, respectively. The influence of four emulsion composition variables, namely, the internal phase volume fraction (ϕ), surfactant ...

  • Case study - Supplemental aeration nearly eliminates filamentous sludge bulking

    The Dubai Investments Park Wastewater Treatment plant in the United Arab Emirates faced challenges in their oxidation ditch due to filamentous sludge bulking, resulting in poor sludge settling in the secondary clarifier. Supplemental aeration was needed to eliminate the filamentous sludge bulking. Challenge: The oxidation ditch is treating an ...

  • Valorization of Romanian silver fir tree bark (Abies alba Mill.) wastes as low-cost sorbent of Cu(II) ions from polluted waters

    Considering recycling as the first option in the hierarchy of sustainable waste management, and also the demand for efficient processes for wastewater treatment with reduced costs, the potential applicability of Romanian Abies alba bark, the main waste from the industrial processing of the wood of mature silver fir trees, as sorbent for Cu(II) has been studied in batch conditions. It was ...

  • Hexavalent chromium removal by using synthesis of polyaniline and polyvinyl alcohol

    Over the past few years, heavy metals have been proved to be one of the most important contaminants in industrial wastewater. Chromium is one of these heavy metals, which is being utilized in several industries such as textile, finishing and leather industries. Since hexavalent chromium is highly toxic to human health, removal of it from the wastewater is essential for human safety. One of the ...
