  • Aerating recycled water on mushroom composting sites affects its chemical analysis and the characteristics of odor emissions

    Recycled water (RW) containing compost leachate can be a potent source of foul odor on mushroom composting sites. Samples of RW were repeatedly collected from storage tanks and pits of 14 mushroom composting sites in England and Ireland. Relationships between the effects of submerged aeration of the RW, the chemical and microbial characteristics of the RW, and the odors emitted were investigated. ...

  • PHASUITE: AN AUTOMATED HAZOP ANALYSIS TOOL FOR CHEMICAL PROCESSES

    INTRODUCTION Safety is an important issue in process design and operation in chemical industry. It is even more critical for modern chemical manufacturing processes, which are either operated under extreme conditions to achieve maximum economic profit, or are highly flexible, such as the specialty chemical or pharmaceutical processes. The importance of safety analysis in process operation is ...

  • Site Vulnerability Assessments for Facilities That Use, Store, or Transport Chemicals

    In response to pressing issues facing the new Department of Homeland Security, over 15,000 chemical and industrial plants may have to evaluate their vulnerability to terrorist attack and improve countermeasures at their facilities. Federal lawmakers are considering two bills requiring facilities to submit site security plans: the Chemical Security Act (Senate Bill S. 157, reintroduced in January, ...

  • Analysis of DNAPL Source-Depletion Costs at 36 Field Sites

    A recent U.S. Environmental Protection Agency (US EPA) expert panel on dense nonaqueous phase liquid (DNAPL) remediation concluded that uncertainty in the costs and benefit of applying source-depletion technologies (i.e., active remediation in source zones) is one key factor that discourages widespread use of these technologies at DNAPL sites (Kavanaugh et al., 2003). To reduce this uncertainty, ...

  • Analysis of physico-chemical and bacteriological quality of drinking water in Mafikeng, South Africa

    Mafikeng, the capital of the North West Province, receives water from two sources, namely the Molopo eye and the Modimola dam. Once treated, the potable water is mixed and supplied to the city via distribution systems. This study was designed to assess the quality of drinking water in Mafikeng and also to determine whether the water from the two sources has an impact on the mixed water ...

  • Spolchemie site remediation and NanoRem field site application

    Site Remediation The Spolchemie site was chosen as one of the NanoRem case study sites, to test two types of nanoparticles (NPs) (zerovalent iron - nZVI and iron oxide NPs) for in situ remediation of BTEX (Benzene, Toluene, Ethylbenzene, and Xylenes) contamination. Nanoremediation was seen as an opportunity to enhance the in situ biodegradation of the BTEX contaminants and to reduce the ...

  • On-site regeneration of transformer oil

    Regeneration of transformer oil at the transformer’s location is an important preventive measure of transformer servicing.   Transformer life time is, in essence, the life time of its insulation system. The most widely used insulation is liquid insulation (transformer oils) and solid insulation (paper, i.e. cellulose insulation). The oil provides for at ...

  • Counting the costs of chemical incidents

    The consequences of a lack of control when using chemical substances in the workplace are well known and apparent.  Any health and safety expert can tell you of at least one major accident whereby poor chemical management policies and procedures have lead to disaster.  Examples include Bhopal, Grangemouth, Flixborough, Seveso and more recently, Buncefield.  Major accidents like ...

  • Parting the Chemical curtain with GreenWERCS

    In May, with very little fanfare, Walmart introduced an extraordinary new tool known as GreenWERCS. GreenWERCS assesses the composition of chemical intensive products -- which is just about any non-food item on a Walmart shelf that you can pour, squeeze, dab or otherwise apply to your body or use in or around your home or car. GreenWERCS analyzes the composition of individual products from ...

  • Further analysis and PMF application to the chemical composition data of IPCAJ's Kashima SPM study

    The Industrial Pollution Control Association of Japan (IPCAJ) has conducted an air quality study. A brief summary has already appeared in previous papers. This set of data was not sufficiently analysed. This study attempts to examine the performance of the Positive Matrix Factorisation (PMF), a recently introduced technique in this field, on this multiple-site Kashima data set. The source ...
