  • Microbiological quality of ice and ice machines used in food establishments

    The ice used in the food industry has to be safe and the water used in ice production should have the quality of drinking water. The consumption of contaminated ice directly or indirectly may be a vehicle for transmission of pathogenic bacteria to humans producing outbreaks of gastrointestinal diseases. The objective of this study was to monitor the microbiological quality of ice, the water ...

  • Control Algae and Improve the Water Quality in Waste Stabilization Ponds

    Due to population growth, accelerated urbanisation and economic development, the quantity of waste water generated is increasing globally. Mainly in low-income areas, a large proportion of the waste water is discharged directly in the environment. When the waste water is treated, the treatment plants may not remove certain pollutants that can have a negative impact on the people and ecosystem. ...

  • Rotating belt sieves for primary treatment, chemically enhanced primary treatment and secondary solids separation

    Fine mesh rotating belt sieves (RBS) offer a very compact solution for removal of particles from wastewater. This paper shows examples from pilot-scale testing of primary treatment, chemically enhanced primary treatment (CEPT) and secondary solids separation of biofilm solids from moving bed biofilm reactors (MBBRs). Primary treatment using a 350 microns belt showed more than 40% removal of ...

  • Predicting water filter and bottled water use in Appalachia: a community-scale case study

    A questionnaire survey was conducted in order to assess residents’ perceptions of water quality for drinking and recreational purposes in a mid-sized city in northcentral West Virginia. Two logistic regression analyses were conducted in order to investigate the factors that influence bottle use and filter use. Results show that 37% of respondents primarily use bottled water and that 58% use a ...

  • Water Security – A Growing Issue with No Easy Fixes

    The issue of water security – access to enough quality water to make it possible to live safely – is a growing concern for many, just ask the communities of Flint and Corpus Christie. The problem is exacerbated when communities and companies come face-to-face over access to water supplies. Wouldn’t the nice idea be to share?  That’s met with disagreements as ...

  • A practical low-cost model for prediction of the groundwater quality using artificial neural networks

    The quality monitoring of water wells is always a costly and time-consuming process. To avoid the unnecessary cost and time of future sampling, applying some powerful and well known prediction models can be a suitable alternative. In this research, the groundwater quality of Amol-Babol aquifer was predicted using the artificial neural network (ANN) model with a data set from 1987 to 2010. ...

  • Case study - Water quality in the Mississippi Basin

    A resilient method for monitoring water quality and nitrate levels in the harsh aquatic environment of the Mississippi River, in section 16, was required by the University of Iowa -IIHR. The monitoring of continually accurate water quality data was important for analysis, in conjunction with the diurnal mussel study of the University of Iowa. Monitoring water over extended periods of time in ...

  • Case study - Water quality monitoring and weather data at Pampulha Lake-Brasil

    In 2010, OTT Hydromet's partner in Brasil,  Hexis began working with CETEC. This resulted in the installation of a buoy, equipped with an automatic profiling system, in early 2013. The project’s objective is the continuous monitoring of the lake’s water quality, with focus on improving this by the 2014 World Cup Games.  Adcon, Lufft and OTT technologies (Hydrolab DS5X ...

  • Changes in the water quantity and quality of the Euphrates river are associated with natural aspects of the landscape

    It has been argued that dam construction and irrigation projects in Turkey and Syria would diminish the flow of the Euphrates River and increase salinity levels. However, previous studies have not systematically defined the baseline changes in the quantity and quality of the river water. In this study, we associate variations in flow quantity and quality of water with natural aspects. We ...

  • Water quality and antifungal susceptibility of opportunistic yeast pathogens from rivers

    Yeasts from water sources have been associated with diseases ranging from superficial mucosal infections to life threatening diseases. The aim of this study was to determine the water quality as well as diversity and antifungal susceptibility of yeasts from two rivers. Yeast levels and physico-chemical parameter data were analyzed by principal component analysis to determine correlations ...

  • Assessment of groundwater quality and health risk in drinking water basin using GIS

    Eğirdir Lake basin was selected as the study area because the lake is the second largest freshwater lake in Turkey and groundwater in the basin is used as drinking water. In the present study, 29 groundwater samples were collected and analyzed for physico-chemical parameters to determine the hydrochemical characteristics, groundwater quality, and human health risk in the study area. The ...

  • Lake hydrology, water quality and ecology impacts of altered river–lake interactions: advances in research on the middle Yangtze river

    Water and mass exchange between rivers and lakes are key processes that maintain the health of the ecology of river–lake systems. Alteration to river–lake interactions have great impacts on water and mass balances. Naturally connected to the middle Yangtze River are the Poyang Lake and Dongting Lake, which are the largest and the second largest freshwater lakes in China. The operation of the ...
