  • Potential impacts of on-site greywater reuse in landscape irrigation

    This study investigated the effects of irrigation with different types of waters on soil, plants, and public health. The test plant was ryegrass grown in 12 planters filled with sandy loam soil and irrigated with three types of waters (4 planters for each type): freshwater, raw domestic light greywater (GW), and treated domestic light GW. The sodium adsorption ratio (SAR), EC, pH and alkalinity ...

  • Analysis of water pricing in Ireland and recommendations towards a more efficient water sector

    Within Ireland, both the public water supply and group water scheme (GWS) sectors are crucial entities in the provision of water supply to individuals. In this study, variances in water charges and operation are assessed via an in-depth survey of 104 GWSs in order to establish the range in both domestic and commercial charges, and also to establish the factors influencing these charges within ...

  • Fate of effluent organic matter during soil aquifer treatment: biodegradability, chlorine reactivity and genotoxicity

    Hydrophobic acid (HPO-A) and transphilic acid (TPI-A) fractions of dissolved organic matter (DOM) were isolated from a domestic secondary wastewater effluent that was polished via soil aquifer treatment (SAT). Fractions were isolated using XAD resin adsorption chromatography from samples obtained along the vadose zone flowpath at a full-scale basin recharge facility in Tucson, Arizona. Changes in ...

  • 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 ...

  • 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 ...


  • Quantification and characterization of greywater from schools

    Survey of schools of different education levels (primary, intermediate and secondary) in Kuwait showed an average greywater generation rate of 7.3 L/p/d and varied in the range of 2.9–16 l/p/d, reflecting the school level of education (i.e. student age). The highest rates were observed for primary schools while the lowest rates were observed in secondary schools where students are more mature ...
