  • 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 ...

  • How to Deal with Arsenic in Drinking Water

    Thanks to recent developments in technology, daily drinking water undergoes a rigorous treatment process for water to be consumable. This is because most ground and natural river waters have a chemical in them called arsenic. Arsenic is a metallic chemical element that is found commonly among rocks and sulfur in the Earth’s crust. Arsenic is known for getting into your drinking water from ...

  • An approach for determining the most critical among a suite of chemical contaminants at a drinking water intake

    An integrated approach for the identification and assessment of the most critical chemical contaminant(s) at a drinking water intake has been developed. It involves the determination of a threshold or critical raw water concentration (CRWC) for target contaminants using the observed overall removal efficiency of a specific water treatment plant (WTP) and regulated drinking water concentrations ...

  • How Arsenic Is Removed from Drinking Water

    Drinking water is a vital and life-giving resource. Clean and filtered drinking water keeps you healthy and safe from harmful chemicals that can immediately harm you or slowly damage your body. That is why arsenic removal from drinking water should be handled by professionals, and it should be done to all possible sources of water that supply homes and businesses. Those who are dedicated to ...

  • Genotoxicity and effects of nanosilver contamination in drinking water disinfection

    This study was conducted to examine the genotoxicity and the influence of silver nanoparticles (AgNPs) contamination when drinking water is exposed to five different disinfection treatments: chlorine, chlorine dioxide, ozone, ozone/chlorine and ozone/chlorine dioxide. Experiments were conducted with water samples of different chemical composition, from three water supply systems in Croatia. ...

  • Tracking disinfection by-products and arsenic removal during various drinking water treatment trains

    In the central Banat region (Northern Serbia), groundwater is used as a drinking water source. Raw water originates from a 40–80 m and 100–150 m deep layer. It contains a high amount of natural organic matter (DOC = 9.17±0.87 mg C/L) with a trihalomethanes formation potential of 448±88.2 μg/L and a haloacetic acid formation potential of 174±68.9 μg/L. A high amount of arsenic (86.0±3.4 μg/L) is ...

  • Guide to Removing Arsenic from Drinking Water

    It’s said that the human body is made up of almost 60 percent water. Is the water you’re putting into your body pure? Many people are unaware of the chemicals and compounds that are seeping into their drinking water and wreaking havoc on their internal systems. Arsenic, for example, can be found in many different areas. In the Northeast especially, well water is more likely to be ...

  • Treatment plant protected by effluent monitor at major drinks factory

    The installation of a BioTector continuous TOC (Total Organic Carbon) monitor to police the front end of Cobevco’s wastewater treatment plant has enabled tight control of the treatment process. Delivering results 20 times faster than laboratory techniques, the monitor at the Elton facility in Cheshire provides advance notice of organic overload so that the plant is able to instantly divert ...


  • 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.

  • Changes of NOM fractions during conventional drinking water treatment process in Riga, Latvia

    In Latvia, as in other countries of the Boreal region, raw water sources contain elevated concentration of natural organic matter (NOM). Originally the conventional water treatment plants (WTP) were mainly designed for removal of turbidity hence the optimization of water treatment processes for more effective removal of NOM is often needed nowadays. In this paper a rapid fractionation (RF) ...
