  • Surface Water Monitoring - Case Study

    Safe operation of a Water Treatment Plant (WTP) requires careful monitoring of the water supply influent to the plant, as a guard for any substances entering the treatment works that could negatively impact treated water quality in the distribution system. One aspect of water quality that has recently garnered more attention from authorities and utilities is Natural Organic Matter (NOM), which ...

  • Time of use tariffs: implications for water efficiency

    Water utilities undertake long term planning for water source security, often with forecast cycles of 20–30 years. Whilst this planning is generally involved with investigations of source water abstraction security and the need to build dams or to increase the recharge rate of groundwater aquifers, planning for water efficiency gains occurs at annual intervals. Most water utilities in Australia ...

  • Looking for efficiency through integrated water management between agriculture and urban uses

    Many urban water systems must cope with water scarcity and climate change and additionally they must be able to fulfil the objectives of environmental protection, efficiency and sustainability. At the end they must provide the expected level of service now and in the future horizons. Some new comprehensive approaches are assessing the total water footprint in a territory using the concept of ...

  • Efficient water utilities: use of performance indicator system and data envelopment analysis

    A number of international initiatives have been undertaken in recent years to develop benchmarking frameworks. Performance indicator system and data envelopment analysis are the two most widely used methods for performance assessment as is evident from the established literature on benchmarking. This paper demonstrates two benchmarking approaches using these two methods for the selected 12 ...

  • Development of efficient characterization parameters for activated carbon used in drinking water treatment

    In many drinking water treatment facilities with an activated carbon (AC) purification step, polar and hydrophilic molecules are substances of concern. Many of the current test methods for AC do not really reflect AC's adsorption capacity for these substances. To develop a fast and economically reasonable parameter that characterizes AC's ability to remove these compounds, three ...

  • Efficient Waste Water Treatment

    Clean drinking water is an essential need of mankind. Often surface water like rivers or lakes is used as drinking water source. To prevent these resources from pollution the effective treatment of waste water is a must. For example in China 75% of discharged waste water is coming from pulp and paper, textile and dyeing industries. To run a waste water treatment plant in the most efficient way ...

  • The spatial and temporal variation of water use efficiency in the Huai River Basin using a comprehensive indicator

    A comprehensive indicator of water use efficiency (WUE) to promote coordinated development between socio-economic and environmental systems was developed. A comprehensive consideration of the social, economic and environmental benefits of water was made in the evaluation index system of WUE and the projection pursuit model combined with chaotic particle swarm optimization was adopted to ...

  • Maximum Efficiency for...Saving Water

    In an attempt to protect our ecological surroundings and minimize the negative effects of industrial processes, it is necessary to purify and recover the waters used during washing operations of sand washing, quarrying and recycling operations. The first step is to recover 100% of the waters used and to eliminate the concentration of sludge, thus Baioni's solutions aim at offering a full sludge ...

  • Smart metering use cases to increase water and energy efficiency in water supply systems

    Efficient water and energy use in water distribution systems is being limited by the lack of sufficient data about water and related energy consumption. Therefore, it is crucial to provide updated and continuous feedback information to water users. This paper describes relevant use cases to improve efficient water use and related energy consumption by water utilities and consumers through the ...

  • Investment efficiency in the Italian water service industry: a benchmarking study using data envelopment analysis (DEA)

    The paper presents a benchmarking study of the Italian water service industry using data envelopment analysis. Sample investigated in the study includes 38 optimal territorial areas (ATOs), where the ATO is a well circumscribed geographical area where the provision of integrated water services is considered efficient. Results of DEA implementation show that the average pure technical and scale ...

  • Water-use efficiency is negatively correlated with leaf epidermal conductance in cotton (Gossypium spp.)

    Water-use efficiency (WUE) may be a useful trait for improving productivity of cotton (Gossypium spp.) under certain water-limited conditions, but it is difficult to measure in the field or in large controlled-environment screening studies. Recently, an easily measured trait, the epidermal conductance of dark-adapted leaves (gdark), was shown to be predictive of whole-plant WUE in soybean ...
