Drinking Water Treatment Insights

  1. Can Innovation Be Achieved With A Tried-And-True Disinfection Technology?

    Since chlorine technology was first used to disinfect drinking water in Jersey City, NJ, in 1908, most waterborne diseases have been eliminated in the U.S. Chlorine is still the most common disinfectant for drinking water and wastewater. Chlorine is also used for disinfection and as a biocide in numerous industries.

  2. How To Combat Coal Ash In Power Plant Wastewater Streams

    Unbeknownst to many, coal ash is one of the most prolific industrial wastes affecting wastewater quality in the country, with more than 100 hundred million tons produced each year. And treating for the byproduct is paramount, with health concerns and stringent regulations in place governing its removal.

  3. How To Know It’s Time To Replace Your RO Membrane

    Reverse osmosis, or RO, is one of the finest technologies to purify water containing high total dissolved solids (TDS) levels of more than 500 ppm. Reverse osmosis plant exporters explain the technology as a separation technology where dissolved and invisible impurities in water are separated with the help of semi-permeable membrane or RO membrane that works under high pressure.

  4. Can This 'Supermolecule' Solve The PPCP Problem?

    Research from the UK has identified a “supermolecule” capable of seeking out and eliminating trace pharmaceuticals that contaminate water supplies.

  5. 4 Steps For Controlling Water Loss At Small Utilities

    The bigger water utilities have the resources, but small utilities face many of the same problems — namely failing pipeline infrastructure and water loss. So what are the solutions and best practices within small utilities’ grasp? One small utility shared its successful approach to controlling water loss as guidance for those with similar struggles.

  6. Process Water: Building A Better System

    With factors such as scarcity, aging infrastructure, and water quality driving the price of municipal water higher, businesses are increasingly considering other means of securing supply. This article examines the trend toward alternatively procured process water and its impact on municipal and commercial interests.

  7. Flow Measurement Management Enables Total Visibility Of Water Use

    Advancements in submetering and cloud-based data analytics help reduce consumption, lower costs, and improve operational efficiency.

  8. Need More Water? Think Ozone-BAC For 'One Water' Resolution

    If you thought reverse osmosis was the one and only choice for potable water reuse, think again. Ozonation followed by biological activated carbon (ozone-BAC) is more suited to inland communities and may be better at removing chemicals of emerging concern (CECs).

  9. How To Weigh Your Options For Arsenic Removal

    Arsenic is among the most well-known, and most feared, drinking water contaminants. Finding its way into water supplies through natural and man-made avenues, the carcinogen poses particular obstacles to those operations responsible for treating it. To get a grasp on those obstacles and the technologies that can best overcome them, Water Online spoke with De Nora Water Technologies.

  10. Why The Future Of Smart Meters Is Now

    The utility of the future will become an integral part of “smart cities.” These forward-thinking cities and utilities will have a complete sense of operations and millions of points of data streaming in at all times, allowing them to operate more efficiently and effectively. One component of the advanced water utility is already in the hands of many: smart meters.
