  • Hierarchical prediction of industrial water demand based on refined Laspeyres decomposition analysis

    A recent study decomposed the changes in industrial water use into three hierarchies (output, technology, and structure) using a refined Laspeyres decomposition model, and found monotonous and exclusive trends in the output and technology hierarchies. Based on that research, this study proposes a hierarchical prediction approach to forecast future industrial water demand. Three water demand ...

  • Permeation testing of PET bottles in the production of mineral water - Case Study

    S.Pellegrino mineral water is recognized globally as one of the leading mineral waters on the market. Flowing from a thermal springs in the heart of the Orobic Alps, its properties were known and appreciated since the thirteenth century. In the late nineteenth century it reached peak popularity. In response to the growing demand for entire cases of water from the springs in 1899 the modern ...

  • Confirming Natural Attenuation Processes at a Coastal Site - Case Study

    Past waste disposal practices at a California coastal site resulted in a groundwater plume containing CVOCs (mainly chlorinated ethenes [CEs] and 1,1-dichloroethane) migrating offshore towards a marine harbor. CVOCs are present in the sediment porewater adjacent to the shoreline, but concentrations decreased significantly between 2000 and 2015, and NA in the marine sediments was suspected. To ...

  • Mobility up the sanitation ladder following community-led total sanitation in rural Zambia

    Scaling the sanitation ladder decreases exposure to various illnesses including diarrheal disease, soil-transmitted helminths and trachoma. In rural Zambia, community-led total sanitation (CLTS) has been deployed to help Zambians scale the sanitation ladder. Analysis of monthly routine surveillance data of village-level sanitation coverage of 13,688 villages shows that villages moved up the ...

  • Get more out of Water Resources Engineering Models

    The effort required to develop water resources engineering models can be significant. But once developed, in many instances the models are only evaluated for a limited, or a single set of conditions. The results and predictions obtained from these evaluations are the ones used in design, presented in reports and conveyed to decision makers and the public. This approach might serve ...

  • Real time data improves winter service in Amsterdam

    In the course of the last winter, the city of Amsterdam tested the mobile road weather sensor MARWIS on a patrol vehicle. They installed the sensor in front of the vehicle shortening the distance between the Bluetooth transmitter and the receiver. Most of the users install the sensor at the back of their car or at the side of their truck, but in this test, the ...

  • Assessing the abatement potential and cost of Chinese industrial water pollutants

    Water pollution is becoming an increasing threat to China's sustainable development. To respond to this challenge, China has pledged to cut emissions of two major water pollutants, chemical oxygen demand (COD) and ammonia nitrogen (NH4), and has disaggregated the national target among provinces. However, the abatement potential and costs have not been thoroughly assessed. This paper aims to ...

  • Systematic risk management approach of household drinking water from the source to point of use

    The water safety plan (WSP) approach is being widely adopted as a systematic approach to improving the safety of drinking water. However, to date, the approach has not been widely used for improving the safety of drinking water in those settings where people have to collect water away from their home. Most rural areas in South Africa still consume unsafe water despite WSP implementation and ...
