  • Barium Sulfate: A Protocol for Determining Higher Site-Specific Barium Cleanup Levels

    Abstract Although different barium compounds are known to exhibit vastly different toxicities, cleanup standards for barium in soil or sediment at environmental corrective action sites are typically based on total barium concentration without regard for the specific barium compounds present. However, the Texas Commission on Environmental Quality (TCEQ) has recently agreed that the insoluble ...


  • New laser-based dust emission monitoring system

    Abstract A new generation of continuous particulate matter concentration monitoring instruments is presented, covering a measuring range of 0 to 1000 mg/m3. The laser-based scattered light instrument gives an improved stability as well as excellent resolution in the low range. This enables high concentration measurement as well as especially low emission monitoring down to 0.01 mg/m3 with a ...

  • Valve actuation and control in the modern refinery

    Introduction The Reliance refinery at Jamnagar in India is one of the largest single refinery sites in the world and virtually all of its valves are motorised with Rotork actuators. Almost 3000 Rotork IQ intelligent valve actuators were installed during the construction of the original refinery, tank farm and power station in the late 1990s, together with a Rotork Pakscan 2E two-wire ...

  • Erosion and Sediment Control: Navigating NPDES Regulations, the SWPPP, and Techniques for Compliance

    Erosion and Sedimentation: Why Are They a Problem? The US Environmental Protection Agency lists sediment as the single most common pollutant in rivers, streams, lakes, and reservoirs. With all the potentially harmful chemicals and substances in the world, it seems odd to many people that sediment—dirt, essentially—is singled out as the major culprit. Yet these particles of ...

  • Insitu mixing of dry and slurried reagents in soil and sludge using shallow soil mixing

    Introduction Recent implementation for the Federal Hazardous Waste Land Disposal Restrictions (LDR) to RCRA and USEPA's willingness to approve on-site treatment and/or containment has allowed in situ treatment methods to become viable options in site remediation. Shallow Soil Mixing (SSM) is one of several in situ mixing techniques now commercially available for use in on-site treatment of ...

  • Prevent hospital acquired infections during construction projects

    The issue of hospital acquired infections is a serious problem. According to several sources, three to four million hospital-acquired infections occur annually, with up to 80,000 fatalities. The costs of these infections are estimated to be between $4 billion and $5 billion per year (Air-Treatment Systems for Controlling Hospital acquired Infections, HPAC Engineering, April 2, 2008).Healthcare ...

  • Incineration

    Introduction: High temperatures, 870 to 1,200 °C (1,400 to 2,200 °F), are used to volatilize and combust (in the presence of oxygen) halogenated and other refractory organics in hazardous wastes. Often auxiliary fuels are employed to initiate and sustain combustion. The destruction and removal efficiency (DRE) for properly operated incinerators exceeds the 99.99% requirement for hazardous waste ...

  • How well does my filter work?

    Contamination control is the key to a cost-effective maintenance operation for hydraulic or engine systems. You depend on your filters, whether hydraulic, lube or fuel, to keep your fluids clean, to keep maintenance costs down, and to ensure reliable operation. At some point, you probably will ask yourself whether or not your filters are really working and doing what they were designed to do. ...

  • Thermal Power - Rehabilitation of Existing Plants Industry - Pollution Prevention Guidelines

    Introduction Pollution Prevention Guidelines to provide technical advice and guidance to staff and consultants involved in pollution-related projects. The guidelines represent state-of-the-art thinking on how to reduce pollution emissions from the production process. In many cases, the guidelines provide numerical targets for reducing pollution, as well as maximum ...

  • Superfund Remediation: The Key to Land Reuse Case Study

    The technology is ready and, with state and federal tax credits waiting, the economics look better than ever: New Jersey, one of the first states to be industrialized, finds itself plagued with the contaminated aftermath of pre-EPA industries: soil contamination. From superfund sites to the gas station whose underground storage tank has been oozing for the last 20 years, every ...

  • Hired metals analyser ensures remediation success

    Cognition Land and Water Ltd, a UK based remediation specialist, has hired a portable XRF metals analyser to improve the speed of remediation work at a project in London’s Kentish Town. The project had a major impact on local residents so timescales were extremely tight but Cognition’s Charlie Jarvis says “It would not have been possible to meet the deadline without the use of ...

  • A Citizen`s Guide to Bioremediation

    What is bioremediation? Bioremediation is a treatment process that uses naturally occurring microorganisms (yeast, fungi, or bacteria) to break down, or degrade, hazardous substances into less toxic or nontoxic substances. Microorganisms, just like humans, eat and digest organic substances for nutrients and energy. In chemical terms, 'organic' compounds are those that contain carbon and hydrogen ...

  • ACS installation at Glowood 100,000ton/y pellet plant achieves 12mg/Nm3 - Case Study

    With increasingly tougher restrictions on industrial air emissions, pellet manufacturers are looking to "future-proof" particulate matter (PM) compliance, cost effectively. One Portuguese producer, Glowood Indústria S.A., has recently installed a brand new type of mechanical cyclone. The most recent results show a remarkable reduction of its PM emissions, from 700mg/Nm3 to under ...

  • Asbestos in Buildings: Practical Guidelines for Building Owners

    Practical guidelines for building owners Overview Friable asbestos-containing materials are present in many public and commercial buildings, schools and factories built before the mid-70's. Regulations in Ontario and some other provinces require building owners and property managers to put in place asbestos control programs, once they are aware of the presence of friable asbestos-containing ...


  • Sources of PCDDs/PCDFs In Cement Kiln Emissions

    Abstract This paper presents data on the source of PCDDs/PCDFs in cement plant stack emissions, demonstrating that these emissions are not necessarily all created by the process. The data potentially demonstrates that some of the PCDDs/PCDFs in the emissions are pre-existing dioxins and furans that are vaporized out of the kiln raw feed. This calls into question the assumption that PCDD/PCDF ...


  • Contribution of natural sources to air pollution levels in the EU - a technical basis for the development of guidance for the Member States

    Exceedences of air quality limit values represent breaches of Community law which can have significant legal consequences for the Member States. For some existing limit values, such as those in directive 1999/30/EC (1st Daughter Directive), an exceedence which is caused by particular natural sources can be ignored for the purposes of ensuring compliance with Community law. For example, Article ...
