WASTEWATER CASE STUDIES AND WHITEPAPERS

  • White Paper: An Integrated Modeling Approach To Predict Flooding On Urban Basin Flooding on urban basins is intensifying due to rapid urbanization. Flooding primarily occurs because of drainage congestion of inland flow and/or over bank flow of river during severe rainfall event. Rapid urbanization is causing a major change in rainfall-runoff phenomenon and the drainage system as well. The overland flow pattern is becoming complex due to huge structural development, and therefore, the correct prediction of surface runoff is becoming a challenging issue. By Dr Ashis Kumar Dey and Seiji Kamioka
  • Mexican Power Plant Meeting Tough Wastewater Challenges
    Mexican Power Plant Meeting Tough Wastewater Challenges Recovering water for boiler feed makeup can come with many challenges for power stations; however, the level of complexity involved with treatment is raised considerably when having to deal with municipal wastewater. By Geoff Hong, Regional Sales Manager – Water and George Di Falco, Communications Coordinator, Eco-Tec Inc.
  • Case Study: Creating A Comprehensive Stormwater Model In A Challenging Environment Data including location coordinates, crown elevation, and invert depths were collected for each structure, and information such as structure dimension and composition were collected for each pipe using Global Positioning System (GPS) technology. As soon as the inventory was finished, it was converted into database format that could then be imported into the stormwater models. By Matthew Luth, Civil Engineer, Burns & McDonnell
  • TETRA® Methanol Dosing Technology Helps Denitrification System Pass Rigorous Performance Test
    TETRA® Methanol Dosing Technology Helps Denitrification System Pass Rigorous Performance Test

    In 2007, Greenville, S.C.-based Western Carolina Regional Sewer Authority (WCRSA) conducted a rigorous performance test on a new tertiary treatment technology to assess its ability to effectively remove nitrate-nitrogen (NO3-N) without using excess amounts of methanol at its Lower Reedy Wastewater Treatment Plant (WWTP).

  • N-Pumps Resolve Clogging Problems, Reduce Energy Consumption
    N-Pumps Resolve Clogging Problems, Reduce Energy Consumption

    In the past, a lift station operation in Ohio had to send crews out daily to unclog one or more pump stations in the county service area. Chronic blockages were attributed to pump design, byproduct grease from restaurants, and medical waste from assisted living and nursing homes along the lines.

  • Pulp And Paper Manufacturer Significantly Increases Production While Complying With Discharge Limitations
    Pulp And Paper Manufacturer Significantly Increases Production While Complying With Discharge Limitations

    A U.S.-based pulp and paper manufacturer required high purity process and boiler feed water. It was using water from a local well and treating it with a 150 gpm conventional RO system operating at 75% recovery, but this was creating 50 gpm of wastewater – over 26 million gallons per year.

  • CA 71 With Ammonium And Nitrate Measurement Metro Waste Reclamation District is one of the largest wastewater treatment plants between the Mississippi River and the west coast. Treated water is discharged into the South Platte River, and contributes 90% of the river’s annual flow at the point of discharge.
  • 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. By Severn Trent Services
  • Vortex Wastewater Pumps Vortex pumps are primary sewerage pumps used to transport are sewerage through the wastewater treatment plant process. Because these pumps are required to handle the raw sewerage including grit and associated storm water runoff debris the abrasion rate is quite high. In this plant the pumps were lasting less than 1 year before severe abrasion caused reduction in tolerances leading to re-circulation. As the sewerage was no longer being efficiently transported to treatment the plants capacity was effectively reduced. Plant was considering replacement after 1 year a t a cost of $8,500.00.

    Microbial contamination of food and beverage products is a potentially catastrophic occurrence resulting in foodborne illness or food spoilage. The same nutritive properties that render cheese and dairy products such a valuable food also provide an ideal growth medium for microbes if contamination occurs.

  • Application Note: Small Team Saves Big Hassles With The Professional Plus Multiparameter Instrument In the past, Shinkle and her colleagues carried separate YSI meters for pH and DO, she notes. Now they use the YSI Professional Plus handheld multiparameter instrument, which allows them to measure pH, DO and temperature with one quick, reliable instrument. By YSI

  • Aerated Biological Nitrogen Removal
    Aerated Biological Nitrogen Removal

    Excess ammonia in receiving waters causes algal blooms that decrease oxygen levels. For this reason, many wastewater treatment plants (WWTPs) must limit ammonia in discharge. Mike Rousey, Hach Company

  • 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. By OI Analytical
  • 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. By Andrew Antonio, Municipal Wastewater Market Manager and Derek Walker, Applications Development Manager

  • Monitoring Aromatic Organics For Optimizing Coagulation

    With the increasing awareness about the negative effects of organics within the water and wastewater treatment process along with increasingly strict water quality regulations, the need for more effective organics removal is becoming more important.
