  • Shining a light on sludge

    HACH LANGE's Solitax turbidity/ suspended solids sensor has been integrated into a tanker reception system to enable the measurement of solids concentration in wastewater movements to and from treatment plants and in trade waste applications for monitoring strengths of imported wastes. JR Pridham Services Ltd (JRP) developed the system to provide visibility of both quantitative and qualitative ...


  • Much light, little heat efficiency

    Energy efficiency in the US is much light and little heat – literally.  Government policy pays a great deal of attention to saving electricity, but focuses little on the thermal energy we waste.  “Policy is electricity-centric in the US. Unless you are making kilowatts, the most efficient investments are off the radar,” said Rob Thornton, president of the ...

  • Material selection for a constructed wetroof receiving pre-treated high strength domestic wastewater

    A constructed wetroof (CWR) is defined in this study as the combination of a green roof and a constructed wetland: a shallow wastewater treatment system placed on the roof of a building. The foremost challenge of such CWRs, and the main aim of this investigation, is the selection of an appropriate matrix capable of assuring the required hydraulic retention time, the long-term stability and the ...

  • A Regulatory Perspective on Maintenance of Disinfection Systems

    ABSTRACTThe Clean Water Act contains requirements to set water quality standards for all contaminants, including bacterial contaminants, in surface waters. Wastewater treatment cannot be expected to remove all of the bacterial contaminants, and as a result, many organisms remain in the waste stream. Therefore, disinfection of treated wastewaters is designed to reduce bacterial numbers to a safe ...

  • Total Energy Management System: Ayers Rock Resort

    Ayers Rock Resort operates in the semi-arid conditions of the Central Australian desert. Since electricity is a major component of running costs, the Resort has installed a computer based preventative maintenance monitoring system, which links all facilities at the Resort and enables tracking of energy costs by process and item of equipment. A monthly energy audit process, together with the newly ...

  • Use of CFD Modelling to Optimise the Design of Upper-room UVGI Disinfection Systems for Ventilated Rooms

    AbstractThe installation of upper-room ultraviolet germicidal irradiation (UVGI) devices in ventilated rooms has the potential to reduce transmission of infections by an airborne route. However, the performance of such devices is dependant on several factors including the location of the lamp and the ventilation airflow in the room. This study uses a CFD model to evaluate the performance of UVGI ...

  • Voices from India on renewable energy sources

    As we all know that all natural resources on this earth are exhaustible sooner than later.  At the current rate in growth of Energy Demand of the world, Fossil Fuels would last in the following order: Oil is expected to last only 45 years, Gas 70 years and Coal 250 years from now.  The good quality coal of low ash content, however, may last only for another 70 to 100 years. Once these ...


  • Go Solar Successfully With These Tips

    Installing solar systems in residential areas on a domestic level is a common sight nowadays. All solar power generation units basically work by converting sunlight in to electricity using photovoltaic cells. Over time, there have been considerable leaps in the technology levels of this invention. This environment free power source with minimal maintenance or everyday cost is now being rapidly ...

  • Solar Energy Costs and the Struggle for Grid Parity

    The price of manufacturing solar panels has dropped significantly in the past decade, and installation has risen as dramatically as prices have fallen. Yet the cost of solar energy varies from state to state and country to country, why? Even though solar panels are cheap to manufacture, the cost of financing, installing and maintaining a system add to the overall price of the product. ...
