  • Wastewater sterilization (purification): completely new method “vortex layer machine”

    The purification and safe disposal (neutralization) of industrial waste water effluents represent a very important ecological problem. The principal problem or requirement involves reducing the concentration of harmful impurities to concentration levels below their maximum allowable concentration limits. In fulfilling this requirement the amount of fresh water consumption needed to maintain the ...

  • Overview of seawater desalination status and challenges

    Introduction World oceans contain over 97.2% of the planet’s water resources. Because of the high salinity of ocean water and the significant costs associated with seawater desalination most of the global water supply has traditionally come from fresh water sources – groundwater aquifers, rivers and lakes. Today, however, changing climate patterns combined with population ...

  • Performance-Based Measurement Systems

    Many of the Environmental Protection Agency's (EPA's) methods used to monitor air, water and soil for environmental contaminants prescribe step-by-step details on how the chemical analysis must be conducted and prohibit any deviations or variations. The EPA has recognized that monitoring equipment and technology have improved tremendously over the last few years; that environmental media do not ...

  • Soil Moisture Applications and Practices Using the HydraProbe Soil Moisture Sensor

    Over the past ten years, environmental monitoring has become increasingly important. Environmental factors such as climate change, dwindling water resources, and threatened habitats are driving the need to monitor the environment and implement better policies to protect it. Many natural processes in the environment are driven by or in some ways related soil hydrological processes. Monitoring soil ...

  • Operator Strategies : Sorting Out the Plastic

    BETTER BUGS Ideas and products in the Better Bugs category attempt to affect the biological components and biochemistry of processes by altering the mix of microorganisms or enzymes present. After all, biology is the foundation of many, if not most, organics recycling systems. Pyrophiles: The first example of Better Bugs involves pyrophilic organisms, bugs that can take the heat. This example is ...

  • Recycling at Special Events.Where Crowds Gather, Recyclables are Sure to Follow

     Special events pose a challenge to recyclers because the waste stream often contains large amounts of single-use products and food discards, and multiple vendors often serve participants. While the type of materials generated varies by event size, venue, and theme, quantities can be substantial. For example, the 30,000 patrons at the Davis, California 1999 Whole Earth Festival produced more ...

  • Enhancements in Meteorological and Hydrological Models Using Soil Moisture Data

    It has long been known that there is a strong relationship between soil water content and the health and yield of crops. But only in the past few decades has science quantified the specifics of these relationships. This research has expanded to develop a relationship between soil moisture levels and the impact on meteorological and hydrological models and forecasts. ...

  • Sick-building syndrome and building-related illness

    Significant health problems linked to very poor indoor air qualityIndoor Air Quality (IAQ) deals with the content of interior air that could affect health and comfort of building occupants. The IAQ may be compromised by microbial contaminants (mold, bacteria), chemicals (such as carbon monoxide, radon), allergens, or any mass or energy stressor are more prevalent than anyone could have predicted. ...

  • ASHRAE Standard 188P: Prevention of Legionellosis Associated with Building Water Systems

    For Presentation at the AWT 2011 Convention and Exposition  The American Society of Heating, Refrigerating and Air-conditioning Engineers (ASHRAE) has developed a proposed Standard Practice that specifies what is required to prevent legionellosis associated with building water systems. Standard 188P is a “Practices” standard – not a “Design” or ...

  • Diversion Deposits, Grants Giving a Boost to C&D Diversion

    Waste characterization studies show a fairly high percentage of potentially recyclable construction and demolition materials going into the landfill. An innovative program in California taps into public sector incentives and private sector investments. Part II IN 1998, the city of San Jose, California conducted a waste composition study to determine what materials were still going into ...
