  • A global clean fossil scenario

    In this article, a so-called Clean Fossil Scenario (CFS) [1], valid for the year 2050, based on a bottom-up demand analysis, is described. It is proposed to mitigate the rise of atmospheric CO2 concentrations by disposing of the CO2 in deep sea and in other reservoirs to limit its liberation to the air. The scenario is clean, because emissions to the environment are reduced drastically compared ...

  • 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 ...

  • Cleaning & maintenance management

    Mercury is a known neurotoxin that is extremely toxic even in small amounts. It directly affects the central nervous and renal systems, causing developmental delays, motor and brain problems like those associated with autism. Mercury’s hidden danger also lies in when at room temperature and exposed, it vaporizes readily. Once it has become an aerosol, it is absorbed into the lungs and ...

  • 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 ...

  • Radioactive Clean-up

    Radioactive, nuclear, or radiation clean-up is considered the most dangerous, difficult, and costly remediation activity after a nuclear disaster or accident.  The contamination may be found in the air, water, and soil, as wells as equipment and buildings (USEPA, 2010).Radioactive material, unlike most matter, is inherently unstable. Over time, the nuclei of radioactive atoms emit what's ...

  • Are Probiotics The Future Of Cleaning?

    Given the choice between a cleaner that reduces germs by 86% and one that all but eliminates them at 99.9%, which one would you choose? If you’re like most people, the answer appears simple – get rid of as many germs as possible. But those nearly 100% effective cleaners aren’t necessarily the best choice. Why? Because they kill all germs, good and bad. Probiotics are ...

    A petroleum plant in Western China needed to remove oil from their wastewater. The user was using a Dissolved Air Flotation (DAF) system; only capable of treating 39,600 US gph ...


  • Korea : Olympic sized clean up

    AIRE-O2® aerators breathed fresh life into the Suyong River and Pusan Harbor Yacht basin, reversing the damage of years of heavy industrial pollution in its upper reaches. Korean officials chose the AIRE-O2® system to improve water quality for the 1988 Olympic Yacht Races due to the aerator’s capabilty to aerate and mix the brackish waters of this vast project. Within days of AIRE-O2® operation, ...

  • Influence of permeation on air/water cleaning of spiral wound membrane NF/RO elements

    To improve hydraulic conditions, periodic air/water cleaning (AWC) is applied to a nanofiltration (NF) spiral wound membrane (SWM) element under permeation conditions to control biofouling and particulate fouling. A pilot study was carried out for 212 days with a vertically positioned SWM element fed by tap water enriched with a biodegradable compound (60 μg acetate-C l−1). Operational parameters ...

  • The tailoring of greenhouse gases to the clean air act – challenges for PSD and title v permitting ahead?

    In anticipation of the promulgation of Clean Air Act (CAA) regulations to control greenhouse gas (GHG) emissions, EPA published the proposed PSD and Title V GHG Tailoring Rule. The proposed GHG Tailoring Rule was published in the Federal Register on October 27, 2009 and has a 60-day public comment period; thus comments are due by December 28, 2009. The proposed GHG Tailoring Rule attempts to ...

  • 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, ...

  • Improving the cleaning cycle in baghouse collectors

    ABSTRACT: Background The reverse pulse jet baghouse has been around for over 45 years and the cleaning cycle has not changed very much since that time. The cleaning cycle is the most important part of the dust collector because it controls efficiency and media life. In a generic baghouse, the cleaning system is comprised of a blowpipe that is located typically approximately three inches above ...
