Even the best-maintained blowers wear down. Timely overhauls prevent catastrophic failure, extend equipment life, and restore blower performance to “like new” condition—often at half the replacement cost.

WASTEWATER CASE STUDIES AND WHITEPAPERS

  • Small Community Leads Central Florida In Potable Water Reuse Implementation

    Altamonte Springs’ implemented a pilot program called the pureALTA project with two primary goals – to serve as platform for future potable water reuse efforts; and to educate the 45,000 residents about the benefits of potable water reuse.

  • Time-Based Treatment Is A Game Changer For Activated Sludge, Granular Sludge, And Densified Sludge

    Time-based batch processing allows WWTPs to gain the benefits of new suspended growth technologies in a much smaller footprint.

  • Article: A Battle Cry For The Nutrient Warriors

    In July 2009, a group of more than 70 leading nutrient removal experts gathered at the Blue Plains Advanced Wastewater Treatment Plant in Washington, DC. The Water Environment Research Foundation (WERF) brought the group together for a workshop to assess the status of our battle to keep excessive nutrient levels from claiming the health of our natural water resources. This gathering of "nutrient warriors" couldn't have come at a better time. Landmark nutrient management activities are already underway.

  • The Cost Of High Solids In Your Wastewater Treatment Plant

    Conventional activated sludge wastewater treatment plants (WWTP) operate with solids (mixed liquor suspended solids ­– MLSS) concentrations ranging from approximately 1500 to 5000 mg/L. In membrane bioreactors (MBRs), typical MLSS concentrations are even higher (10,000 to 12,000 mg/L). 

  • Retrofitting Water Systems With The Best Meters For The Job

    Although not every water, wastewater, or industrial design engineer or operations manager is familiar with the advantages of the V-Cone differential-pressure (DP) meter design, they are certainly familiar with the problems it can solve. Here is a step-by-step description of how V-Cone meters with + 0.5 percent accuracy offer better alternatives in applications currently being failed by other metering technologies.

  • A New Era In Blower Control Efficiency

    A common misconception among wastewater plant managers is that pressure-based blower controls remain an industry “best practice” for aeration. The problem is this approach was developed during an age when most blowers were constant speed machines with outputs that could only be governed by the manipulation of inlet valve position or header pressure. Newer self-tuning, airflow-based control systems save energy, improve effluent, and reduce greenhouse gas emissions.

  • Accurate Measurement Of Sewage Flow Made Possible By Clamp-On Technology

    Read about how Welsh Water sought innovative solutions, exploring clamp-on technology for accurate sewage flow measurement.

  • Case Study: Prosonic S Provides Reliable Control Of Filtration For Raw Sewage Water

    In the inlet of the plant, the raw sewage water is filtered through 3 automated systems. The filtration systems are equipped with an endless mesh, which captures the solid materials. By Endress+Hauser, Inc.

  • Springdale, Arkansas, Wastewater Treatment Plant Operators Call Headworks Screens 'Bulletproof'

    The Poultry Capital of the World is a city in northwest Arkansas in the heart of the Ozark Mountain range. Springdale, Arkansas, the fourth largest city in the state, is the headquarters for Tyson Food Corporation, the world's largest meat-producing company. The city was founded in the mid-1800s and has been a hub for agriculture and industry in the region since then. In addition, the region is home to outdoors activities like fishing, hunting, camping, boating, etc., and the natural, outdoors life is enjoyed by many residents as well as visitors to the area.

  • Xylem Pairs Godwin And Flygt Pumps To Assist With Emergency Tunnel Project

    The city of Atlanta faced a critical problem in 2013 when the city’s Nancy Creek Tunnel failed due to years of sediment buildup.

WASTEWATER APPLICATION NOTES

  • Monitoring IWW Effluents With FP 360 sc Oil-In-Water Sensor

    This application note explores a test which demonstrated significant improvements in Oil-in-Water monitoring of industrial wastewater in comparison to the weekly grab sample analysis method.

  • Sink Or Swim: A Comparison Of Submersible And Surface Mixers For Anoxic And Anaerobic Tank Mixing

    With increasing requirements for enhanced nutrient removal, many wastewater plants are adding anoxic and/or anaerobic tanks in their secondary treatment systems. There are multiple options for enhanced nutrient removal including, but not limited to, the A2O (Anaerobic, Anoxic, Aerobic) process, the UCT or MUCT (Modified University of Cape Town) process and the Bardenpho process.

  • Pile Cloth Media Filtration For Clean Utilities

    Cooling towers and boilers consume the most fresh water in the industry, with industrial process waters carrying the balance. Power plants and refineries use more water volume for the cooling process than any other area of the facility. Mining and food and beverage industries consume higher volumes for their processes. Clean water may come from a range of sources, including clarified surface waters, groundwater or properly treated wastewater (reuse) sources.

  • Improved Efficiencies In TOC Wastewater Analysis For Standard Method 5310B And EPA Method 415 Total organic carbon (TOC) measurement is of vital importance to the operation of water treatment due to organic compounds comprising a large group of water pollutants. TOC has been around for many years, and although it is a relatively simple analysis in theory, operational efficiency is paramount.
  • Optimizing Brine Flow In A Geothermal Power Plant

    Different flow meter technologies were used in this geothermal power plant to monitor and measure brine. However, these traditional technologies failed. That’s where Panametrics PT900 Portable Ultrasonic Flowmeter was able to help.

  • Scrubber Application

    This customer supplies district heating and electricity for the region of Sønderborg. For one of their waste applications a MAG meter failed within 6 months, and was successfully replaced with a Panametrics Aquatrans AT600.

  • Magnetic Flow Meters Improve Recycling Of Gas Well-Produced Water

    As old gas & oil fields play out, newer methods must be used to extract resources from areas where they are locked in layers of shale. One current technique is known as “fraccing,” in which high pressure water is pumped into the well shaft to “fracture” the rock layers, allowing more natural gas to escape and be collected. However, this technique poses a number of environmental problems, including contamination of water with hydrocarbons, solid particulates, and scale producing ions — making it unsuitable for reuse.

  • Ultrasonic Flow Meters Improve Biogas Measurements

    As interest in biogas grows, more attention is being paid to measuring biogas flow, which has long been a problem area in process measuring technology.

  • Analyzing Total Organic Carbon In Sea Water

    The analysis of Total Organic Carbon (TOC) in seawater can be both challenging and expensive. The concentration of organic carbon in seawater is of considerable interest. The effect this matrix can have on TOC analyzers can lead to rapid consumable turnover, costly maintenance and repairs.

  • A Non-Intrusive Solution For Measuring Wastewater Flow In A WWTP's Iron Pipes

    A municipal association needed to understand if wastewater was being equally distributed across two cast iron pipes within its wastewater treatment plant. Learn how clamp-on ultrasonic measurement helped successfully measure the flow.
