  • Combining Decentralized And Centralized Wastewater Treatment Strategies To Solve Community Challenges
    Combining Decentralized And Centralized Wastewater Treatment Strategies To Solve Community Challenges

    To sustain the environment and smart community growth while protecting public health, engineers, municipal health officials, and regulators need innovative wastewater treatment solutions. The latest evolution of decentralized systems can efficiently handle residential and commercial daily flows and are a cost-effective alternative to the large, centralized wastewater treatment plants of the past. 

  • Increased Biogas Yields With Biological Hydrolysis
    Increased Biogas Yields With Biological Hydrolysis

    Municipal wastewater operations require significant energy to operate, but the biogas produced solely through anerobic digestion of sludge isn’t typically enough to offset the electricity and heat load demand at plants. Advanced anaerobic digestion technology, however, can change the equation so wastewater treatment plants can get closer to energy neutrality and in some cases even generate an excess.

  • Confronting The Campus Steam Conundrum
    Confronting The Campus Steam Conundrum

    Residents of an Iowa town were told not to drink their tap water this month when dangerous levels of manganese were found in the supply. And most concerning may be the fact that nobody seems sure how long the contamination has been affecting residents.

  • A Fresh Case For Investing In MBR To Improve Capacity And Effluent Quality

    The membrane bioreactor industry has matured past the point of being an experiment or a niche technology. Advancements, as well as more recent adoptions by high-profile users, are providing wastewater treatment plant operators with more incentive and a better business case to retrofit their systems.

  • Conducting Accurate Conductivity Measurement In Industrial Applications

    While some water quality parameters may get more attention in industrial settings, few are more critical than conductivity. Understanding conductivity monitoring for industrial applications — where it is needed, how it works, and how to leverage the appropriate instruments and standards in order to pinpoint it — will unlock huge gains in efficiency, effectiveness, and regulatory compliance.

  • How To Be More Industrious About Water-Quality Measurement

    Precise water quality is critical for municipal water treatment operations, but many industrial applications have even more rigorous requirements, regulations, and guidelines to follow. The energy, pharmaceutical, food processing, and other industrial fields require exact water quality in order to function efficiently.

  • WWTP Wanted: Total Package, Self-Starter, Willing To Relocate

    When it comes to providing wastewater treatment plant (WWTP) solutions for isolated, low-volume applications, it is true that good things can indeed come in small packages.

  • Keeping A Lid On It: Identifying And Intercepting Potential Cooling Water System Upsets

    A wide range of industrial operations rely on cooling systems to function. And, in turn, these systems require cooling water to function. So, it stands to reason that a wide range of water treatment issues need to be considered and addressed so that cooling water system upsets are avoided and everything continues to run as it should. Oftentimes, an efficient industrial operation depends on efficient monitoring and treatment of cooling water.

  • Enhancing WWTP Nutrient Removal, Without Overblown Costs

    For those who appreciate the old maxim about catching more flies with honey, the logic of creating a more favorable biological environment for better biological nutrient removal (BNR) makes perfect sense. Worldwide implementations of flat-sheet membrane aerated biofilm reactor (MABR) technology are doing exactly that — in less space, with less energy, and with lower operating expenditure (OPEX) for aeration and chemical treatment. Here’s how:

  • Relieving The Pressure Of Monitoring Peak Boiler Water Efficiency

    Industrial operations across the gamut leverage boiler water, the liquid that passes through a boiler and is converted into steam, thus powering operations around the world. But not all of them do as much as they could to ensure peak boiler water efficiency. Through the proper treatment considerations and quality measurement knowledge, every industrial player can make the most of this central process.

  • Pushing Water Reuse To The Extremes

    Large-scale water-reuse treatment plants have had sustainable impact in populated areas where the volume of water to be treated and reused in a concentrated area makes them practical. Today, the flat-sheet membrane aerated biofilm reactor (MABR) technology that is delivering high-quality wastewater treatment to remote locations is poised to realize the promise of sustainable water reuse in those same locations.

  • MABR: Familiar WWTP Principles, Better Results

    Wastewater treatment plant (WWTP) designers and decision-makers tasked with finding more cost-effective performance for challenging applications want new options.

  • Oxidation And AOP: The Last Lines Of Defense Against Harmful Algal Blooms

    Secondary metabolites of algae — including algal toxins and taste and odor compounds triggered by a harmful algal bloom — can find their way into source water, creating the risk that they will ultimately reach the water treatment plant to cause water-quality problems. Here is a checklist of considerations for mitigating those effects through cost-effective oxidation, or combined oxidization processes, across a variety of source water conditions.

  • Dissolved Air Flotation: Elevating The Efficiency Of Algae Removal

    Understanding the nature of harmful algal bloom causes, effects, and remediation strategies is key to choosing optimal water treatment plant technologies for improved resilience against this emerging threat to water quality. Whole-cell removal of algae via dissolved air flotation technology helps in maximizing physical removal of intact algal cells and biomass and reducing disinfection byproduct potential.

  • How Harmful Algal Blooms Can Affect Your Water Treatment Plant

    Headlines in 2018 were dominated by the red tide along Florida’s Gulf Coast, which persisted for months, causing human respiratory illnesses, the deaths of dozens of Florida’s beloved dolphins and manatees, and hundreds of millions of dollars in lost tourism revenue and cleanup costs. Here are insights on how to forestall becoming the next city to make national headlines related to harmful algal blooms.

  • Harmful Algal Bloom Threats To Potable Water: Establishing Resilience

    Changing climate and other environmental conditions are intensifying the frequency and severity of harmful algal blooms (HABs).
