  • Simultaneous removal of aqueous Zn2+, Cu2+, Cd2+, and Pb2+ by zeolites synthesized from low-calcium and high-calcium fly ash

    In this study, zeolites were synthesized from low-calcium (LCZ) and high-calcium (HCZ) fly ash, respectively. Subsequently, the zeolites were tested for their removal effectiveness for four aqueous cations, namely, Zn2+, Cu2+, Cd2+, and Pb2+, as a function of contact time, pH value, adsorbent dosage, and initial concentration of heavy metals. Both zeolites were ...

  • Vattenfall`s Cogeneration Power Plant Reuter West - Case Study

    The cogeneration power plant “Reuter West” was erected as a base load power plant in the vicinity of the existing “Reuter” plant. The two hard coal fired 300 MW units D and E were commissioned in 1987 and 1989. Today the cogeneration units supplying electricity and thermal energy are operated by Vattenfall Europe GmbH. The heart of each power plant is the boiler where the ...

  • Spatial differences in trace element bioaccumulation in turtles exposed to a partially remediated coal fly‐ash spill

    Large‐scale releases of environmental contaminants from industrial facilities can cause considerable damage to surrounding ecosystems and require remediation. The expense and/or undesirable environmental side effects of physical removal may constrain remediation efforts. In 2008, approximately 4.1 million cubic meters of fly‐ash were released into the Emory River at a coal burning power plant ...

  • Biodegradability and methane production from secondary paper and pulp sludge: effect of fly ash and modeling

    The effect of fly ash on biodegradability and methane production from secondary paper and pulp sludge, including its modeling, was evaluated. Three tests with fly ash concentrations of 0, 10 and 20 mg/L were evaluated at 32 °C. Methane production was modeled using the modified Gompertz equation. The results show that the doses used produce a statistically significant increase of ...
