  • How Installing Arsenic Drinking Water Treatment Can Save Your Life

    Arsenic is an element so associated with its toxicity and harmful effects on the human body that the word itself is often used for any kind of general poison. While the exact ways that exposure to the metalloid attacks various organs and systems is still not fully understood, studies throughout the scientific community are continually determining that ingesting arsenic through drinking water can ...

  • The Benefits of Biological Treatment for Drinking Water

    The biological treatment of drinking water is undertaken using both organic and inorganic contaminants, and can be used to treat groundwater and surface water. These contaminants, contrary to what the name implies, are applied to strip away the factors that make the water unsafe for drinking until it is potable—meaning drinkable. If you would like to learn more about the benefits of ...

  • Algae control in drinking water treatment - case study

    For the Ministry of Agriculture in Cyprus, LG Sound b.v installed 33 LG Sonic, ultrasonic devices in the Limassol water treatment plant, to prevent bad odour and taste to the water caused by geosmins in the water. The earthy taste problem persisted during summer of 2010 and various physical, chemical and biological tests were done in order to check the process efficiency, which showed problems ...

  • Drinking Water Aesthetics Improve with Ozone Treatment

    High quality water sources for municipal use are dwindling, forcing utilities to seek alternate water sources. Many times, aesthetics are the only problem preventing the use of these alternate water sources for potable purposes. Although typically used as a disinfectant, ozone offers municipal water purveyors the benefits of being the strongest commercially available oxidizing agent (Table 1). ...

  • Evaluation of chitosan as a natural coagulant for drinking water treatment

    Chitosan, a natural biopolymer, was evaluated for its ability to be used as a coagulant to treat water for potable use both in isolation and in combination with other water treatment technologies, specifically ion-exchange and activated carbon. Chitosan was found to be very effective for particle removal at doses far below those required for equivalent turbidity removal by inorganic coagulants. ...

  • A critical evaluation of two point-of-use water treatment technologies: can they provide water that meets WHO drinking water guidelines?

    Point-of-use (POU) technologies have been proposed as solutions for meeting the Millennium Development Goal (MDG) for safe water. They reduce the risk of contamination between the water source and the home, by providing treatment at the household level. This study examined two POU technologies commonly used around the world: BioSand and ceramic filters. While the health benefits in terms of ...

  • Solutions for Safe Drinking Water Through Biological Water Treatments

    Most people across the U.S. expect to turn on their faucets and have immediate access to clean drinking water. The truth is, it wasn’t until 1974 that Congress passed the Safe Water Drinking Act with the goal of regulating the nation’s public water supply. Over the years, the SWDA has been amended to include water sources as well, such as rivers, lakes, springs and groundwater wells ...

  • Water Treatment Plant (Drinking Water) Indian Oil Corporation Limited, India

    W.O.G Groups responded to the challenge of providing safe drinking water to the Indian Oil Corporation Limited township by undertaking a Drinking Water Treatment Plant of Capacity 5.76 MLD, including 1 year O&M. CHALLENGE: The raw water is to be treated for the removal of Manganese, iron, turbidity, suspended solids, colour, organic matter and pH The design of ...

  • Making your drinking water safe with biological water treatment

    As society becomes more environmentally conscious, it is important that your community is provided with its natural necessities in an eco-friendly manner. One of these natural necessities includes adequate drinking water. Many companies use chemical treatment methods to help cleanse and purify water resources, but such methods are often at the expense of your local environment. Some water ...

  • Natural Disaster Recovery & Drinking Water

    Clean water is one of the fundamental pillars of modern civilization, and a major priority for local and municipal government.  When disaster – hurricanes, tornadoes, earthquakes – strikes, one of the first priorities is to rehabilitate water treatment and distribution systems.  Water main and pipe breaks, pressure loss, and backflow can all act to introduce external ...

  • Technology development trajectory for drinking water treatment: a comparative study between South Korea, Thailand, and Lao PDR

    This paper reports on a study to compare the technological trajectory of drinking water treatment for the past 30 years, from the 1980s to the 2010s, in South Korea, Thailand, and Lao PDR. There are significant differences in water treatment technology in the three countries, resulting from factors such as national regulations, economic conditions, and water policies. These act either as ...

  • A novel technology to improve drinking water quality using natural treatment methods in rural Tanzania

    It is estimated that one billion people worldwide do not have access to treated drinking water. This paper reports on an investigation into the potential of indigenous or natural water treatment methods as alternatives to conventional chemical water treatment methods. The seeds of five natural plant species—Vigna unguiculata, Phaseolus mungo, Glycine max, Pisum sativam, and Arachis hypogea—were ...

  • Biological ammonia removal field studies for drinking water treatment

    In order to study the applicability of biological ammonia removal from drinking water, field experiments with 10 L/h flow rate were carried out at a case-study area, where raw water contained arsenic, iron, manganese, dissolved gases (methane, aggressive carbon dioxide) and ammonia.
