  • How to use Electrocoagulation for Effective removal of Phosphorus in Wastewater

    In this article, we will be discussing phosphorus, the effects of elevated phosphorus levels on an ecosystem, and how innovative electrocoagulation technology can be sustainably used for effective removal of phosphorus in wastewater & water sources. What is Phosphorus? Phosphorus is one of the most common nutrients on the planet. It is formed naturally in nature, and ...

  • What Is Denitrification?

      In Fluence’s membrane aerated biofilm reactor (MABR) technology, simultaneous biological nitrification-denitrification takes place within a single tank due to a bacterial biofilm that forms on its aeration membrane. Nitrates, which are vital to the growth of plants, must be removed during the wastewater treatment process Nitrogen, the most prevalent element in Earth’s ...

  • Kerrville, Texas - Case Study

    BioCOPE, Inc. first added 30 gallons per day (gpd) of ERI to the Jefferson lift station to control grease, odor and corrosion at the Quinlan lift station. Two weeks later, a second pump was installed, and the daily treatment rate was reduced to a combined rate of 25 gpd. One pump operates continuously for 24 hours per day, while the second pump operates 13 hours per day. This allows the highest ...

  • Optimizing air flows to aeration basins – Case Study

    As a result of clean energy mandates and the rising cost of energy, wastewater treatment facilities around the country are retrofitting their instrumentation to run highly efficient, cost-effective, clean facilities. To reduce emissions and produce clean energy, solid wastes are often digested in large digester tanks to reduce the volume of waste (sludge) and produce more biogas, which is then ...

  • Wastewater Treatment: Out with Conventional, in with Sustainable Wastewater Treatment

    The question?Water is one of the world’s most vital resources. It is critical to the survival of every living creature on the planet. The average human can only go a few days without consuming water in some capacity. Health experts stress drinking fluids throughout the day to remain properly hydrated. However, in some parts of the world, water is hard to obtain. Either there are no sources ...

  • Algal blooms in drinking water reservoirs

    Frequent outbreaks of algal blooms are degrading water in drinking water reservoirs worldwide, making the water unusable. Algal blooms can sometimes be so massive that they are visible from outer space. Rising temperatures, prolonged water stagnation, extreme weather and increased runoff of nutrients from urban and agricultural lands are all compounding the algae problem. Especially in the ...

  • Background & Challenges, Citronelle, Alabama Case Study

    The town of Citronelle, Alabama consists of approximately 5000 people located about an hour from the Gulf Coast within the boundaries of Mobile County. Geographically unique, Citronelle is built atop a giant salt-cored dome that is still rising steadily, within the eastern Interior Salt Basin in southwest Alabama. With over 2400 kms (1500 miles) of inland waterways, Alabama has one of the highest ...
