Neutralizing Dissolved Solids Aeration Concerns
Neutralizing Dissolved Solids Aeration Concerns

The presence of dissolved solids presents both physical and financial challenges for aeration diffusers in any wastewater treatment operation and can be particularly problematic in high-concentration industrial and food-processing applications. Here are some warning signs, insights, and solutions for coping with conditions that can lead to excessive dissolved solids accumulation.

  • Case Study: The Power To Make A Change For The Better
    Case Study: The Power To Make A Change For The Better There’s no arguing the fact that the Power Generating industry is a 24/7 business. And although an industrial pump may be a small piece of the overall operational picture, a failed pump can cause more than a few problems - even if a backup is at hand. Paired with the decrease in manpower that most plants have suffered throughout the last several years, the overall goal of maximizing effectiveness of even the best plants is jeopardized today.

  • Dissolved Oxygen Measurement
    Dissolved Oxygen Measurement

    One of the most important measurements in the determination of the health of a body of water is its dissolved oxygen content. The quantity of dissolved oxygen in water is normally expressed in parts per million (ppm) by weight and is due to the solubility of oxygen from the atmosphere around us.

    The Dallas County Water and Sewer Authority (DCWSA) in Selma, Alabama recently found itself in a tough spot: under the scrutiny of the Alabama Department of Environmental Management (ADEM). The wastewater treatment system needed better means for control. Ammonia, TSS, cBOD, and TKN readings were out of compliance. Then they discovered a new testing method known as simplified-TKN (s-TKN), and with it, better process control to achieve regulatory compliance.

  • 4 Benefits Of Utilizing Reverse Osmosis Wastewater Treatment For Reuse
    4 Benefits Of Utilizing Reverse Osmosis Wastewater Treatment For Reuse

    When a municipality or business wants to reuse their wastewater, some applications require more treatment than others due to the quality of the wastewater. Many standard wastewater treatment systems consist of pretreatment, primary treatment, and secondary treatment stages. By the end of the secondary stage, a majority of the pollutants, solids, organics, inorganics, and metals have been removed or reduced. This is where reverse osmosis wastewater treatment can be utilized in a third stage process.

    In water and wastewater treatment, chemistry is king. Treatment options are evaluated depending on the quality of water to be treated and the treatment application. Treatment systems including AOP systems, are designed to specifically target certain contaminants and remove or reduce them from the water. This takes places through the power of chemical reactions. Even biological treatments involve chemistry at their core.

  • Global Perspective On Water In The Circular Economy
    Global Perspective On Water In The Circular Economy

    Isn’t it ironic that our beautiful blue planet, covered 70 percent with water, is struggling to meet citizens’ water needs? Yes, and the reasons are obvious. Out of the Earth’s total water, less than 3 percent is available as freshwater, and a portion of it is actually accessible. Uneven distribution of fresh waterbodies and population across the globe further skew water supply and demand ratios. Also, climate change, deforestation, desertification, droughts, floods, and depletion of natural waterbodies resulting from anthropogenic and natural activities add to these miseries.

    You’ve decided on a wastewater treatment system integrating an AOP system process. Well, now you’re going to need a way to evaluate your system’s performance. While it may seem to run perfectly fine, it’s difficult to really gauge how efficiently the process is running at a glance, especially an advanced oxidation process as it is typically focused on removing micropollutants from a water source.
