  • 9 Things Your Respiratory Protection Program Must Include

    Many think that getting a respirator fit test is all that is needed.  Unfortunately, it’s much more than that. The OSHA Respiratory Protection Standard 29 CFR 1910.134 has many requirements in addition to respirator fit testing. If respirators are worn by any employees, companies must have a written Respiratory Protection Program. The one exceptionis if the only respirators in use are ...

  • Protect Your Respiratory System

    The air around you keeps you alive. But in certain circumstances, it can cause you serious injury, illness or death. To stay alive and healthy, you need air which is clean, free of toxic gases and other contaminants, and contains the right amount of oxygen. Most of the time, the air around you at home, on the street and at work fills the bill. But under certain circumstances, the air contains ...

  • Cardiff WWTW aeration optimisation through scientific control

    Aeration optimisation of a 16 basin SBR plant running in ICEAS (Intermittent Cycle Extended Aeration System) mode was under taken by changing the operating parameters from the traditional design of dissolved oxygen (DO) control to a scientific approach using respirometry. Measuring the critical oxygen point for carbonaceous and nitrification bacteria and combining this with in-situ Oxygen Uptake ...

  • Bioventing

    Introduction Bioventing is a promising new technology that stimulates the natural in situ biodegradation of any aerobically degradable compounds in soil by providing oxygen to existing soil microorganisms. In contrast to soil vapor vacuum extraction, bioventing uses low air flow rates to provide only enough oxygen to sustain microbial activity. Oxygen is most commonly supplied through direct air ...

  • BM Respirometry Study Toxicity & Biodegradability of a Refinery polymer stream, when treated in the activated sludge process of the plant - Case Study

    This “batch system” respirometer consists of: a single thermostatically controlled vessel, divided into two interconnected compartments with closed recirculation loop between the two. A constant air flow is supplied via a ceramic diffuser in the conditioning compartment, and a combined oxygen/temperature sensor in the reaction compartment controls the DO and temperature. Both ...

  • Workers` silica exposure at Fracking sites far exceeds OSHA Limit, NIOSH study finds

    The concentration of silica in the air workers breathe exceeded occupational health criteria at all 11 hydraulic fracturing sites tested by the National Institute for Occupational Safety and Health, the American Industrial Hygiene Association announced July 31. Researchers measured the silica levels of more than 100 personal breathing zone samples at fracking sites in five states, finding levels ...

  • Effect of high solids concentration on hydrodynamics and mass transfer of a three-phase airlift reactor for marine sediment bioremediation

    The more restrictive limits for environmental pollution control imposed nowadays require the development of new biological technologies. Multiphase reactors including slurry reactors have become reactors of choice for chemical and biochemical applications. In the present work, three-phase airlift reactors are proposed as an alternative to mechanically stirred systems and slurry bubble columns for ...

  • The In Situ Bioremediation/Groundwater Remediation Process

    In-situ groundwater bioremediation is a technology that encourages growth and reproduction of indigenous microorganisms to enhance biodegradation of organic constituents in the saturated zone. In-situ groundwater bioremediation can effectively degrade organic constituents which are dissolved in groundwater and adsorbed onto the aquifer matrix. The Adventus In Situ Bioremediation/Groundwater ...


  • Loading of an Anaerobic Packed Bed for Treatment of a High Strength Gray Water

    ABSTRACTIn preparation of long-duration manned space flight, biological treatment systems have been evaluated for mission specific waste streams consisting of a high-strength gray water. The purpose of the work was to determine the appropriateness of using nitrification and denitrification to treat the urine-humidity condensate waste stream and to determine the optimal loading rate for the bench ...

  • CO2 Enrichment in Horticulture... A `Good Life´ for all?

    If you’ve ever watched that classic 1970s TV series, ‘The Good Life’, you might have some idea of the work involved in attaining self-sufficiency. As funny and light-hearted as it was, ‘The Good Life’ offered many insights into the unenviable lot of the vegetable gardener. To its credit, the programme was also ...

  • Combining HVME and Enhanced Bioremediation for Gasoline Contamination in Groundwater

    A leaking underground storage tank at a commercial petroleum retail site located in Haskell, Texas resulted in soil and groundwater petroleum hydrocarbon contamination. This contamination, including benzene, toluene, ethylbenzene, and total xylenes (BTEX) and total petroleum hydrocarbons (TPH) migrated down-gradient below a road and neighboring property. Access below the adjacent roadway was ...

  • Fires at Composting Facilities: Causes and Conditions

    The subject of fires at composting facilities is a bad news/good news situation. The bad news is that fires are more common than we realize. Ask a group of facility operators if they have had to deal with a fire, and the majority will quietly admit they have. The good news is that we don’t realize that fires are fairly common at composting facilities. Most are neither frequent nor destructive ...
