How UF Membrane Fiber Strength Impacts Reuse Success
How UF Membrane Fiber Strength Impacts Reuse Success

Advanced technology and more widespread acceptance are driving a growing number of municipalities to adopt the practice of wastewater reuse. Ultrafiltration (UF) has been proven a key in this process, but operators have struggled to keep up with repairs or having to replace older hollow-fiber membranes. Recent advancements in manufacturing have produced more durable membranes that accomplish the task at a lower cost based on the total lifecycle.

  • Total Kjeldahl Nitrogen: Simplified With s-TKN™
    Total Kjeldahl Nitrogen: Simplified With s-TKN™

    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.

  • Membrane Degassing and Debubbling of High Viscous Fluids with 3M™ Liqui-Cel™ Membrane Contactors
    Membrane Degassing and Debubbling of High Viscous Fluids with 3M™ Liqui-Cel™ Membrane Contactors

    Increased gas content often leads to problems with bubble formation in highly viscous fluids. 3M™ Liqui-Cel™ Membrane Contactors can provide a simple, compact, and efficient in-line solution for removing bubbles from viscous liquids before they create problems in a process operation.

  • Primary Wastewater Treatment: Influent Monitoring
    Primary Wastewater Treatment: Influent Monitoring

    The raw sewage entering a wastewater treatment plant comes from a variety of sources. In addition to effluent from domestic users, effluent from industrial users and storm water run off can be present.

  • Mapping And Identifying The Source Of Water Quality Issues
    Mapping And Identifying The Source Of Water Quality Issues

    A Southern U.S. municipality experiencing taste and odor issues in a certain neighborhood was also having difficulty maintaining chlorine residual levels in the area. Biological growth was suspected, however, water leaving the treatment plant met and exceeded all water quality requirements. After several investigations, the source of contamination in the distribution system could still not be identified.

  • Harmonics Reduction Methods
    Harmonics Reduction Methods

    There are several basic methods for reducing harmonic voltage and current distortion from nonlinear distribution loads such as adjustable frequency drives (AFDs). Following is a description of each method, along with each method’s advantages and disadvantages.

  • The Importance Of Measuring Total Organic Carbon
    The Importance Of Measuring Total Organic Carbon

    Organic carbon compounds vary greatly. In fact, one of the first lessons in most introductory Organic Chemistry courses explains that the number of possible carbon compounds is virtually infinite due to carbon’s ability to form long, chain-like molecules. While chromatographic methods like gas chromatography (GC) or high-performance liquid chromatography (HPLC) are able to make quantitative determinations for specific compounds, the user must first know which specific compounds to look for.

  • Application Note: Simultaneous Determination Of Total Bound Nitrogen (TNb) And Total Organic Carbon (TOC) In Aqueous Samples Total bound nitrogen (TNb) consists of dissolved ammonia, nitrates, nitrites, amines, and other organic nitrogen-containing compounds. TNb measurements represent an alternative to Total Kjeldahl Nitrogen (TKN) analysis for rapid screening of industrial wastewater, drinking water,agricultural run-off, and surface waters.

  • 4 Misconceptions Of AOP For Wastewater Treatment
    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.

  • Combining Biosolids Waste Streams?  Not So Fast…
    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.

  • Sludge Thickeners: The Good, The Bad, And The Smelly
    Sludge Thickeners: The Good, The Bad, And The Smelly

    Management of wastewater sludge is a core responsibility of treatment plant operators. With this responsibility comes common challenges that must be overcome.  These include controlling odors so as to have a minimal impact on the surrounding community and minimizing hauling costs for its disposal.  Getting a handle on both of these responsibilities and more can be much easier with the proper sludge-thickening equipment.

  • Calibrating Success: Improved Tools To Maintain Flowmeter Accuracy
    Calibrating Success: Improved Tools To Maintain Flowmeter Accuracy

    Water utilities with highly successful monitoring programs tend to share a common trait: they have a well-defined plan for calibration that emphasizes frequency and tracking. However, when done properly, this process is time-consuming and often leads to unnecessary labor and downtime. The good news is that advanced metering technology is available for plants to get a better handle on the instrument’s performance with significantly less effort.

  • Sludge Sampling For Polymer Selection – Critical For Project Success
    Sludge Sampling For Polymer Selection – Critical For Project Success

    Polymers — the chemicals used in wastewater to thicken sludges and facilitate the removal of water — are critical to the operational efficiency of sludge-thickening equipment.  Unfortunately, it’s common practice at treatment facilities to order and install equipment before even considering what the ideal polymer might be for the sludge produced at the specific plant. This flawed process is time consuming, disruptive to plant operations, and can become very costly.

  • How To Boost Wastewater Treatment Capacity Within An Existing Footprint
    How To Boost Wastewater Treatment Capacity Within An Existing Footprint

    Municipalities can find themselves in a real bind when wastewater treatment operations are strained by population growth. That’s because facilities are either landlocked and can’t expand at their current location, or the prospect of building an addition isn’t in the budget. When the bottleneck is at the digesters — the tanks where microorganisms break down waste — there are some common-sense strategies treatment plants can employ to address those growing pains.
