  • Controlling Bacteria In a Clean Room Environment

    Maintaining the integrity of a cleanroom is a constant battle. The first step to deciding which method, or combination of methods, to employ is to identify the prime sources of contamination. There are three prime sources of contamination through which the integrity of a cleanroom might be breached. First, there is the human element. While many processes might be automated, many situations remain ...

  • Effects of UV Ozone for air room and deep cleaning disinfection purposes Version:1.0

    According to the EPA and American Medical Association (AMA), studies indicate that indoor levels of many pollutants may be 25 times and occasionally more than 200 times higher than outdoor levels. While older buildings present the issue of a large buildup of contaminants over time, today’s buildings are built so air tight that the health risks may be even greater. According to the EPA, ...

  • Clean goes green

    Her daughter's eyes were pink and puffy. The child's nose was scratchy and runny. Nancy Figueroa of Jamaica Plain did everything she could to make her daughter well: She bought one medicine after another; did more wash than a 24-hour laundromat; gave to charity her daughter's stuffed animals that might be carrying dust, including the little monkey that young Katherine clung to for comfort. Still ...

  • Indestructible Pumps for Clean Water

    Sulzer pumps are used in the production of drinking water in many cities around the world. The special qualities that these pumps possess can be seen at the Zurich Municipal Water Utility. There, the operators have to cope with rising land and energy prices and a challenging topography. A small water flea plays a major role in Zurich. It swims around in a container of drinking water with some of ...

  • Cleaning & maintenance magazine

    An analysis of the lighting industry shows a trend away from incandescent bulbs to fluorescent bulbs. Incandescent bulbs use more energy and are more costly and less effective than fluorescent bulbs in the amount of artificial light they produce, as fluorescents produce more lumens than incandescents. Using fluorescent bulbs, however, is not entirely without risk because they contain mercury, a ...


  • The natural way to clean wastewater

    John Todd founded Ocean Arks International in the 1980s, where he started to experiment with processes that mimic natural ways to purify wastewater. He built a greenhouse and ran sewage through a series of tanks, with plants suspended in the flowing waters, and constructed marshes made of sand and gravel. No chemicals were added, but plenty of aquatic creatures from snails to small fish were ...

  • Control of Aerosol Contaminants in Indoor Air: Combining the Particle Concentration Reduction with Microbial Inactivation

    ABSTRACT An indoor air purification technique, which combines unipolar ion emission and photocatalytic oxidation (promoted by a specially designed RCI cell), was investigated in two test chambers, 2.75 m3 and 24.3 m3, using nonbiological and biological challenge aerosols. The reduction in particle concentration was measured size selectively in realtime, and the Air Cleaning Factor and the Clean ...

  • Case study - Safety, Protection against corrosion and cabinet pressurisation in refineries

    The environment in a refinery is highly corrosive. This makes it necessary to deploy control systems not only to protect staff but also to protect the equipment controlling the processes, in order to ensure their reliability. Bioconservacion has equipment that is specially designed for the safety of staff, and for protecting against corrosion in control rooms and cabinet pressurisation equipment. ...

    Most work place accidents could be prevented with proper working gas detection equipment. Gas detection is a critical component for safety programs for any environment; it should be given the highest priority and attention to detail to avoid any accidents and unnecessary work place injuries or deaths. Here are some suggestions on how to keep your work environment safe: 1.   Read the gas ...

  • Biological water treatment effective in Saddle Lake

    Three transparent pipes connected to a network of hoses and gauges stretch from the floor to the 14-foot ceiling in a back room of the Saddle Lake water treatment plant. Water burbles through the pipes, mixing with a material that looks like black sand. The particles are actually expanded clay aggregates that provide the surface needed for water-cleaning bacteria to live on. The bacteria remove ...

  • Efficient Operation of Lighting, Hot Water and Air Conditioning: Hotel Inter Continental Sydney

    To improve its environmental performance and save nearly $300,000 per year, the Hotel Inter Continental Sydney changed some practices that seemed insignificant in themselves but which collectively, wasted massive resources. The changes cost around $275,000 and no adverse affect on guest amenity. They included lowering the power of lights that were too bright, lowering the temperature of ...

  • Case study - Organic particulate filtration

    Overview A food products company that mixes various types of waxes and other components to make the base for chewing gums was faced with the issue of cleaning up a slightly odorous, visible emission being exhausted from two of their process lines. The components of the emission were hot particles of chewing gum and some volatile organic compounds (VOC's). The particles would quickly clog ...

  • Case study - ETO sterilizer abatement
