WASTEWATER CASE STUDIES AND WHITEPAPERS

  • Wastewater Pond Uses Floating Wetlands For Nutrient Removal
    Wastewater Pond Uses Floating Wetlands For Nutrient Removal

    A series of artificial floating wetlands, each planted with 70 individual plant plugs, is introduced to a Louisiana correctional facility's oxidation pond to remove nutrients causing discharge compliance issues. The wetland treatment technology is designed around the same principles as a naturally occurring wetland, however by expanding the available underwater surface area, it encourages greater microbial growth spurring on enhanced nutrient removal.

  • The Important Role Of Ultrasonic Flowmeters In Biogas Production
    The Important Role Of Ultrasonic Flowmeters In Biogas Production

    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. By Dick Laan, Ultrasonic Flow Product Manager, and Rick Lowrie, Water & Wastewater Industry Manager, KROHNE, Inc.

  • Case Study: Pumping Up Safety, Efficiency, And A Smarter Design
    Case Study: Pumping Up Safety, Efficiency, And A Smarter Design When Progress Energy learned about the opportunity to install new, more efficient and easier-to-maintain pump technology for less than they could rebuild their current pumps, the decision was simple. By The Gorman-Rupp Company
  • Fairbanks Nijhuis Protecting New Orleans

    Originally constructed from the 1920s to 1949, the Gulf Intracoastal Waterway (GIWW) is one of America’s most remarkable transportation arteries. The New Orleans District U.S. Army Corps of Engineers operates and maintains the GIWW in Louisiana, and maintains its six locks for both navigation and agricultural purposes.

    Water Utility Turns To State-Of-The-Art UV Technology To Help Address Drought

    The 2013 year was the driest in recorded history with many areas of the San Joaquin Valley reporting groundwater levels more than 100 feet below previous historical lows. 

  • Mahr® Bar Screens Replace Two-Stage Screening System
    Mahr® Bar Screens Replace Two-Stage Screening System

    In 2004, the Department for Regional Development announced plans to upgrade the Limavady Wastewater Treatment Works, which was part of a 28 million dollar capital works program in Northern Ireland.

  • Case Study: Water Reuse In Florida, USA The US wastewater minimization market is highly affected by a few key drivers: pollution prevention, water recycling, and water reuse. These drivers have been brought about by water shortages, increasing population, and more stringent environmental regulations -- all of which increase the cost of clean water and lead to the reduction, and the need for more efficient use, of water supplies.
  • WWTP Overcomes Odor Issue
    WWTP Overcomes Odor Issue

    The City of Crystal Lake is located about 45 miles northwest of Chicago with a population of nearly 45,000 people. Like many wastewater treatment plants, urban sprawl and suburban development puts the Crystal Lake Wastewater Treatment Plant near a host of commercial and residential neighbors, including a high school immediately west of the plant. Plant managers were very forward thinking, and wanted to be good neighbors to those occupying the surrounding area. They wanted to take steps to reduce — and hopefully eliminate completely — any odor issues from the plant.

  • Revolutionary Wastewater Disinfection In Land Of 'Plain' Living A local wastewater treatment plant in Pennsylvania Dutch Country has employed a revolutionary technology: the first ever microwave-powered ultraviolet disinfection system used by a sequencing batch reactor (SBR) treatment plant.

  • On-Line Phosphorous Measurement Takes The Guesswork Out Of Alum Treatment
    On-Line Phosphorous Measurement Takes The Guesswork Out Of Alum Treatment

    Phosphorous promotes eutrophication in surface waters and helps create conditions for algal blooming and oxygen depletion. Some phosphorous removal can occur naturally in a conventional biological wastewater treatment facility, but the result is not reliably compliant with increasingly strict limits on permissible phosphate levels in effluent discharged to receiving streams, ponds and lakes. By Bob Dabkowski, Hach Company

  • Reducing Total Phosphorus In Water Resource Recovery Facilities
    Reducing Total Phosphorus In Water Resource Recovery Facilities

    Monitoring phosphate during the wastewater treatment process allows for fine-tuning and optimizing chemical dosing for removal of phosphate, which provides significant cost savings to the plant while protecting the aquatic environment downstream of the facility.

  • Improved Efficiencies In TOC Wastewater Analysis For Standard Method 5310B And EPA Method 415
    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.

  • Advanced On-Line Instrumentation Helps DAF Systems Lower Costs
    Advanced On-Line Instrumentation Helps DAF Systems Lower Costs

    Many food processors use dissolved air flotation (DAF) to remove fats, oils and grease (FOG) and suspended solids from their wastewater streams.

  • Optimizing Air Flows To Aeration Basins
    Optimizing Air Flows To Aeration Basins

    As a result of clean energy mandates and the rising cost of energy, wastewater treatment facilities around the country are retrofitting their instrumentation to run highly efficient, cost-effective, clean facilities. To reduce emissions and produce clean energy, solid wastes are often digested in large digester tanks to reduce the volume of waste (sludge) and produce more biogas, which is then used as fuel in the cogeneration process. However, a clean environment calls for not just clean air and clean energy, but clean water as well.

  • WWTP Utilizes Online Instrumentation And SCADA To Keep Operating Costs Low And Effluent Quality High
    WWTP Utilizes Online Instrumentation And SCADA To Keep Operating Costs Low And Effluent Quality High

    Providing the best value to wastewater customers requires a team of operators that have a deep sense of ownership and are committed to continuous improvement. Such is the case for the operating staff at one wastewater treatment plant whose progressive attitude and a philosophy of “do it right” led them to an investment in online instrumentation and SCADA for compliance, monitoring, and control.

  • Alcoholic Beverage Fusel Alcohol Testing With Static Headspace
    Alcoholic Beverage Fusel Alcohol Testing With Static Headspace

    A static headspace method was developed using Teledyne Tekmar automated headspace vial samplers to meet the method requirements of the Alcohol and Tobacco Tax and Trade Bureau of the US Department of the Treasury (TTB) method SSD: TM:2001 for testing fusel alcohols in alcoholic beverages.

  • Bringing Efficiency And New Confidence To BOD5 Analysis Biochemical Oxygen Demand (BOD) analysis is the test everyone loves to hate—and for compelling reasons. By Bob Dabkowski, Hach Company
  • Bringing Efficiency And New Confidence To BOD₅ Analysis

    Biochemical Oxygen Demand (BOD) analysis is the test everyone loves to hate—and for compelling reasons.

  • Importance Of Measuring UV Transmittance (UVT) For UV Disinfection

    UV disinfection systems disinfect water using UV light at the 254 nm wavelength. UV light at this wavelength actually destroys the DNA of microbiological material in the water which prevents dangerous viruses such as cryptosporidium and e-coli from reproducing and causing harm.
