    8/25/2017

    You might say that there’s a lot wrong with the water industry — problems including infrastructure, financing, and scarcity — but there’s also a lot going right. In this Q&A, Water Environment Federation (WEF) President Rick Warner is a source of insight and optimism.

  2. Need More Water? Think Ozone-BAC For 'One Water' Resolution
    8/25/2017

    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).

  3. Expertise And Innovation Help Large Water Intake And Treatment Processes Run Smoothly

    8/7/2017

    Aeration is a critical part of the wastewater treatment process and one of its biggest energy consumers. As such, there is no reason why aeration should be left behind as plant processes and technologies become more advanced.

  8. It’s Time For Industrial Treatment To Find A Phosphorus Alternative
    8/7/2017

    Amid growing concerns around algal bloom, industrial operations are under pressure to stop using phosphorus-based water treatment technology. But transition to an alternative can be daunting.

  9. Why India Needs More Wastewater Treatment Plants
    8/3/2017

    As India hurtles towards a more developed economy, one of the casualties has been the deteriorating state of our environment. Rapid industrialization has, unfortunately, hiked up the number of pollutants in our surroundings. One of these pollutants is wastewater. Management of wastewater through wastewater treatment plants in India has become an imperative of our cities today.
