  • Rhode Island Wastewater Plants Key To Water Quality Reversal

    Despite evidence that often points to the contrary, many bodies of water around the country stand as prime examples of how environmental quality can be improved with the proper will and effort. Take, for instance, Narragansett Bay, located on the north side of the Rhode Island Sound. Located near some of America’s oldest settlements, the bay has ...

  • Do You Need a Microfiltration or Ultrafiltration Membrane System for Your Plant?

    Determining whether or not an industrial plant needs a microfiltration (MF) and/or ultrafiltration (UF) membrane system isn’t always as straightforward as it seems. While these systems are not essential for every industrial process, when thoughtfully implemented within an intake, process, or waste stream, they can go a long way in improving a facility’s efficiency and/or cutting ...

  • Frequency pressure regulation in water supply systems

    In water supply systems, pressure management in most cases is proven to be the most cost-effective activity related to water loss control. As an advanced method of pressure control, it is possible to use variable frequency drives for centrifugal pump control. Pressure regulation can be performed with constant pressure or with proportional pressure control. The application of proportional ...

  • A look at some contaminants regulated in drinking water

    The U.S. Environmental Protection Agency regulates just over 90 contaminants in public drinking water systems. They include manmade chemicals as well as naturally occurring contaminants from rocks and soil. A look at some of the contaminants that fall under federal or state regulations: ARSENIC: Enters drinking water through eroding natural deposits in the ground or mining and other ...

  • Reducing the Economic Friction of Regulation

    Last month, we looked at two distinctly different bioenergy business models that are merging. Energy profit centers and waste cost-recovery facilities are learning the benefits of each other's business model. The resulting projects generate maximum revenue with lower production costs. The same kind of business model duality occurs in biomass energy regulation. There are more than two kinds of ...

  • Decoupling dependence on natural water: reflexivity in the regulation and allocation of water in Israel

    Since 1999, Israel has secured a decoupling between the total water supplied and water derived from the natural environment through surface and groundwater. Between 2007 and 2010, this decoupling enabled a cut of over 20% in natural water use, while maintaining overall supply volumes despite drought. By 2009–2010, natural water supply had been reduced to the levels of the early ...

  • Gray Water Characteristics and Implications on Regulations for Sustainable Water Reuse

    Different types of gray water in terms of origin (from bathing, kitchen and laundry activities) and in terms of type of source (medium and low-income residential housing and a hotel) have been studied in Gaborone, Botswana during 2004, with respect to BOD5, TSS, TP, pH, fecal coliforms and conductivity. Results show an expected high variability. No statistically significant difference was ...

  • Nutrient Regulation on Streams: The Macrophyte Quandary

    ABSTRACTSince promulgation of the Clean Water Act in the 1970s and implementation of technology-based treatment requirements, such as secondary treatment for publicly owned treatment works, the nation’s water quality has improved dramatically. Current water quality concerns are no longer attributed to excessive loads of carbonaceous and nitrogenous biochemical oxygen demand. Rather, the largely ...

  • Opinion: Environmental regulation in the 21st century

    INTRODUCTION I start with a statement of the obvious. The aim of environmental regulation is to produce measurable improvements in the environment. But how much environmental regulation expresses the desired environmental outcome? How much, on the other hand, sets out the regulatory process? Not enough of the former, too much of the latter. That unremarkable statement of aim is at the ...
