Wastewater Treatment Insights

  1. How To Use ATP And DNA In A Wastewater Nitrification Monitoring Plan

    Ammonia removal is a key metric for assessing wastewater treatment facility performance. This is because ammonia contributes to aquatic life toxicity. Furthermore, nitrogen, along with phosphorus, is a driver of receiving water eutrophication. Eutrophication, which simply is an over-enrichment of nutrients, can be detrimental to environmental and public health. It can result in harmful algae blooms, dissolved oxygen depletion, fish kills, and other damaging impacts.

  2. 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.

  3. Analyzing Water Quality Parameters When Choosing AOP Systems For Water Treatment

    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.

  4. Moving Forward On Desalination

  5. Learn How De Nora’s Acquisition Of MIOX Is Making An Impact

    In February 2019, De Nora announced the acquisition of MIOX® Corporation, an Albuquerque-based  electrochemical expert. Five months later, Bryan Brownlie, Managing Director – De Nora Water Technologies Texas LLC, answers some of the key questions we have been asked about the rationale for the acquisition and the changes that have happened since.

  6. 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.

  7. What Is The Best Key Performance Indicator To Evaluate The Efficiency Of Your AOP System?

    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.

  8. Defining High Quality Biosolids: Exploring Options To Create A Market For Biosolid Products

    Water resource recovery facilities (WRRFs) are already aware of the idea that biosolids can be a valuable commodity. Consequently, there is opportunity to grow this market. The use of biosolids can create products that have value and generate a customer demand that ultimately leads to an economic incentive for WRRFs. There are several factors that contribute to the success of biosolid products, like the quality of biosolids and information available about how and where to use high quality biosolids.

  9. 4 Misconceptions Of AOP For Wastewater Treatment

    Advanced oxidation is a rather complex wastewater treatment process. The general concept of how the process works can be difficult to grasp at first, and the number of possible oxidation methods can seem daunting. Therefore, you turn to the internet for information, and try to analyze together all the information you find using various online resources. However, everything doesn’t always fit right, and you come up with ideas that may not be quite true.

  10. Combining Biosolids Waste Streams? Not So Fast…

    The idea of combining two systems into one sounds like a common-sense solution to simplifying operations.  Wastewater treatment plant operators have been experimenting with this concept by combining waste activated sludge with primary and septage waste streams with the goal of lowering system complexity.  The reality of these efforts is proving, in many cases, to be problematic.
