  • Vitrified galvanic Waste chemical stability
    Journal of the European Ceramic Society, 2007
    Co-Authors: A.c. De Silva, Sonia Regina Homem Mello-castanho
    Abstract:

    Chemical stability evaluation is the main parameter to harmful Industrial Waste Treatment process for legal ratification process. The inertization by glassing is an interesting technological option for the Treatment of galvanic solid environment harmful Wastes mainly due to the possibility to avoid its heavy metals content toxic action. In this study a vitrification process for galvanic Waste incorporation with good chemical stability was presented. Glasses with up to 40 wt.% of galvanic solid Waste by modifications in the basic composition of soda-lime glasses were prepared. After fusing at temperatures up to 1300 ??C the glasses were characterized by FT-IR, XRF and XRD methods. The chemical stability was evaluated by hydrolytic, alkaline and acid attacks assays. Glasses with homogeneous and high chemical stability were obtained. ?? 2006 Elsevier Ltd. All rights reserved.

  • Hexahydro-1,3,5-trinitro-1,3,5-triazine (RDX) reduction by granular zero-valent iron in continuous flow reactor
    Environmental Science and Pollution Research, 2018
    Co-Authors: Amalia Terracciano, Jie Ge, Agamemnon Koutsospyros, Benjamin Smolinski, Xiaoguang Meng, Per Arienti
    Abstract:

    Wastewater streams containing hexahydro-1,3,5-trinitro-1,3,5-triazine (RDX) are subject to regulatory discharge regulations that require processing through Industrial Waste Treatment. Thus, the development of easy-to-apply technologies for the Treatment of RDX-laden Wastewater streams is imperative. In the present study, the reduction of RDX by granular zero valent iron (GZVI) in batch and column experiments was investigated. Preliminary batch tests conducted under both oxic and anoxic conditions showed that after 3.0 h of reaction with GZVI, RDX was mainly converted to formaldehyde (CH2O), nitrate (NO3−), and ammonium (NH4+). Column filtration tests showed that preTreatment of the GZVI media with acid wash and low influent pH (4.0 ± 0.1) achieved 99% removal of RDX up to 5000 bed volume. BOD tests carried out on the post-Treatment streams showed increased biodegradability of the treated Wastewater, leading to a lower environmental impact for the final Waste.

  • Application of Biotechnology for Industrial Waste Treatment
    ChemInform, 2006
    Co-Authors: Volodymyr Ivanov, Yung-tse Hung
    Abstract:

    Environmental biotechnology concerns the science and practical knowledge relating to the use of microorganisms and their products. Biotechnology combines fundamental knowledge in microbiology, biochemistry, genetics, and molecular biology, and engineering knowledge of the specific processes and equipment. The main applications of biotechnology in Industrial hazardous Waste Treatment are: prevention of environmental pollution through Waste Treatment, remediation of polluted environments, and biomonitoring of environment and Treatment processes. The common biotechnological process in the Treatment of hazardous Waste is the biotransformation or biodegradation of hazardous substances by microbial communities. Bioagents for hazardous Waste Treatment are biotechnological agents that can be applied to hazardous Waste Treatment including bacteria, fungi, algae, and protozoa. Bacteria are microorganisms with prokaryotic cells and typically range from 1 to 5 mm in size. Bacteria are most active in the biodegradation of organic matter and are used in the Wastewater Treatment and solid Waste or soil bioremediation. Fungi are eukaryotic microorganisms that assimilate organic substances and typically range from 5 to 20 mm in size. Fungi are important degraders of biopolymers and are used in solid Waste Treatment, especially in composting, or in soil bioremediation for the biodegradation of hazardous organic substances. Fungal biomass is also used as an adsorbent of heavy metals or radionuclides. Algae are saprophytic eukaryotic microorganisms that assimilate light energy. Algal cells typically range from 5 to 20 mm in size. Algae are used in environmental biotechnology for the removal of organic matter in Waste lagoons. Protozoa are unicellular animals that absorb organic food and digest it intracellularly. Typical cell size is from 10 to 50 mm. Protozoa play an important role in the Treatment of Industrial hazardous solid, liquid, and gas Wastes by grazing on bacterial cells, thus maintaining adequate bacterial biomass levels in the Treatment systems and helping to reduce cell concentrations in the Waste effluents. Microbial aggregates used in hazardous Waste Treatment. Microorganisms are key biotechnology agents because of their diverse biodegradation and biotransformation abilities and their small size. They have high ratios of biomass surface to biomass volume, which ensure
