  • 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 ...

  • Sustainable wastewater separation treatment systems coupled with nutrient and water reducing greywater reuse technologies

    Nationally and internationally, pressure is increasing to introduce nutrient reducing, water conserving and recycling measures for sustainable residential and small community water/wastewater systems. Reports of inadequate water quality and quantity are being reported daily. Over the past thirty years the federal government and State of Alaska have invested over 4 billion dollars installing piped ...


  • Reactive and real power compensation with DSTATCOM and BESS for mitigation of flicker

    Voltage flicker, a phenomenon of annoying light intensity fluctuation, caused by rapid change in industrial and domestic load such as electric arc furnaces (EAF), rolling mills, welding equipments and pumps operating periodically, has been a major concern for supply utilities, electricity regulatory agencies and costumers. The FACTS devices like SVC's, STATCOM and custom power devices like ...

  • 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 ...


  • Climatic Catastrophes And The Role Of Solar Power

    The world is witnessing a drastic negative change in the climate of all regions owing to the rapid increase in the burning of fossil fuels as well as utilization of other non-renewable sources for energy production. These worst fears of increasing natural disasters, extreme weather and melting of Earth’s icecaps were confirmed by the recent release of IPCC’s climate assessment report. ...
