  • Magnetic Water Conditioner

    I am sure you have heard about hard water before, and also know that hard water is bad for our health. If you check the kettle for boiling water, you will see limescale which will affect the efficiency of energy. There are several solutions for water softening, especially to lower the calcium and magnesium in water. 1. The easiest way is just to boil the water, the calcium hydroxide and magnesium ...

  • Effect of water quality of antibiotics by RO/NF

    This study addresses the possibility for nanofiltration (NF) and reverse osmosis (RO) membrane processes to serve as an alternative to remove low levels of selected antibiotics from wastewaters and surface waters given changing water conditions such as pH and presence of natural organic matter (NOM).  Preliminary experimental results obtained with a dead-end filtration apparatus suggest that ...

  • Bacterial deposition in unsaturated porous media as related to surface properties

    Transport of Escherichia coli, Pseudomonas fluorescens and Bacillus subtilis in silica sand under water-unsaturated conditions was investigated using column experiments. It was hypothesised that bacterial deposition was due to their interactions within the pore environment, which was a function of their surface physicochemical properties as well as pore water chemistry. Surface thermodynamic ...

  • Local self-governance, ethnic division in slums and preference for water supply institutions in Kolkata, India

    This paper investigates the preferences for institutional mechanisms for improved water supply services across different ethnic communities in slums of Kolkata. The Muslim community prefers privatization of water supply as against paid public supply. The backward caste community prefers both paid public delivery and privatization. Residents of non-notified (NN) slums prefer paid public ...

  • Total Dynamics of Quartz–Water System at Ambient Conditions

    New data on the dissolution and growth of quartz in acid, nearly neutral and slightly alkaline solutions at ambient conditions are presented. During batch dissolutions, aqueous Si-concentrations increased nonlinearly towards limit values. During parallel growth experiments, however, the high Si-concentrations corresponding to 13-fold supersaturation with respect to quartz did not decreased. To ...

  • Evaluation of temperature impacts on drinking water treatment efficacy of magnetic ion exchange and enhanced coagulation

    Magnetic ion exchange (MIEX®) is an emerging technology for disinfection by-product (DBP) precursor removal in the drinking water industry. Although recent research has demonstrated that this technology is capable of achieving excellent natural organic matter (NOM) removal, there is paucity of published research showing the efficacy of ion exchange (IX) technology in cold water ...

  • Study on the joint probability distribution of irrigation water volume and irrigation water efficiency

    Using the copula method, the joint probability distribution of irrigation water volume and efficiency is constructed, and their joint return period is also described to reveal the encounter probability of irrigation water volume and efficiency. Furthermore, the conditional probability of irrigation water efficiency with different water volumes is built to show the quantitative effects of flow on ...

  • World Water Day

    Today is World Water Day. An annual event which is focused on raising awareness around universal clean, fresh water issues and sustainable water solutions. This year marks the 23rd World Water Day since the first recorded event in 1993. It was proposed in the 1992 United Nations Conference on Environment and Development and has become a popular event around the world, particularly in highlighting ...

  • Partial nitrification in MBBRs for mainstream deammonification with thin biofilms and alternating feed supply

    A new principle for mainstream nitrogen removal through nitritation followed by anammox was studied in a two-stage moving bed biofilm reactor (MBBR) configuration. The first stage was optimized for nitritation by using thin biofilms and a feed alternating between synthetic mainstream wastewater at 15°C and, for shorter periods, synthetic reject water at 30 °C. The exposure of the biofilm to ...

  • Calcium removal by softening of water affects biofilm formation on PVC, glass and membrane surfaces

    Literature data on the effect of calcium on biofilm structures induced a preliminary study. The effect of calcium removal by water softening (<1.0 mg Ca2+.L−1) under real-world drinking water conditions on biofilm formation was studied in a pilot plant with reverse osmosis (RO) membranes and in a laboratory-scale biofilm production unit (BPU) with plasticized polyvinyl chloride ...

  • Arctic Polar Research - A Global Responsibility

    Due to climate change and geopolitical trends, the Polar Regions (particularly the Arctic) are increasingly becoming the focus of scientific, political, and economic interests. Much of the global climate is driven by forces that originate in the Arctic. The Arctic sea ice is receding faster than climate models have predicted, and the movement of freshwater into and around the Arctic plays an ...

  • Examination of a coupled supply- and demand-induced stress function for root water uptake modeling

    Vegetation water use is closely related to its biophysical functioning and is often under stress from various environmental factors. However, commonly used root water uptake models only consider the stress from root zone moisture availability. There is a need to incorporate the stress from both the above-ground factors and root zone water condition. In this study, a newly developed coupled ...
