  • Evaluating Different Blower Technologies On A Wire-To-Air Basis
    Evaluating Different Blower Technologies On A Wire-To-Air Basis

    In the absence of official third party specifications on energy efficiency, it is difficult to evaluate and compare blower technologies fairly and effectively. The lack of readily available evaluation tools leads to misinformation and unfair comparisons between technologies. Further, the performance verification process is difficult to prove.

  • Howard County, Maryland Sets The Pace In Restoring Chesapeake Bay Ecosystem
    Howard County, Maryland Sets The Pace In Restoring Chesapeake Bay Ecosystem

    Howard County, Maryland, Bureau of Utilities recently completed the $92-million Addition No. 7 project at the Little Patuxent Water Reclamation Plant (LPWRP) to improve the quality of the plant’s effluent discharge and to reduce harmful nutrients reaching Chesapeake Bay. The project’s various increments took over five years to complete and incorporated innovative design solutions and state-of-the-art technologies for denitrification, aeration and disinfection. The project presents a model for Maryland’s 66 largest wastewater treatment plants and possibly procurement of municipal facilities elsewhere facing increasingly stringent regulatory changes.

  • Garrison Brewing Case Study
    Garrison Brewing Case Study

    ClearBlu provided duplexing in-ground lift stations and a self-cleaning waterfall hydroscreen for the brewery who self-installed the equipment.  ClearBlu design and instructions made it possible for the brewery to install the lift stations and screen themselves, as well as to have the screen stand fabricated locally.  ClearBlu lift stations are fabricated from fiberglass which resists deterioration from acidic wastewater and are self-cleaning.  Round basins can be stirred so that they never have to be cleaned out.

  • Versatility Of Thermal Mass Flow Meters
    Versatility Of Thermal Mass Flow Meters

    There are many well documented flow meter technologies that are essentially trying to accomplish the same thing: measure fluid flow rate. Some of the technologies that are entrenched in the market, such as flow meters that utilize differential pressure as the measurement principle, are well understood by customers. Thermal mass flow meters however, such as the Magnetrol® Thermatel® TA2, are a rapidly growing technology that is continuously evolving.

  • Development Of MBR Suitable For Retrofit With Flat Sheet Membrane
    Development Of MBR Suitable For Retrofit With Flat Sheet Membrane

    In sewage works of Japan near bay areas, the tightening of restrictions on nitrogen and phosphorus has resulted in greater needs for reconstruction and replacement of infrastructure, to switch from the conventional activated sludge process to the advanced treatment process without newly expanding aeration tanks.

  • Salisbury Retrofits Existing Process With An AquaPASS® System To Comply With The Chesapeake Bay Initiative

    The Salisbury Township WWTP in Gap, PA utilized a conventional activated sludge (CAS) system prior to being retrofi tted with an AquaPASS Phased Activated Sludge System in May 2008.

  • 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.

  • Mounting Evidence Of Denitrification System's Efficacy In Cold Weather
    Mounting Evidence Of Denitrification System's Efficacy In Cold Weather

    For more than three decades, wastewater treatment plants have faced increasingly stringent regulations regarding total maximum loads for nutrient discharges.

  • Saving 65 % Energy In Aeration

    At a municipal WWTP in southern Sweden, a new aeration control system was installed together with new screw blower and Sanitaire Silver Series II LP diffusers in one of the two treatment lines.

WASTEWATER APPLICATION NOTES

  • Disinfection: Chlorine Measurement In Wastewater And Regulated Discharge Requirements Homes, industry, schools, and businesses all generate sanitary waste, or sewage. Sewage treatment is a multistage process that cleans up wastewater before discharge or reuse. In the final step of the treatment, disinfectants are added to kill disease-causing organisms. Common disinfectants are chlorine gas and sodium hypochlorite. Chlorine dosage levels are designed to leave almost no residual in the wastewater after treatment
  • 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.

  • 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.

    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.

  • Application Note: Preliminary Performance Study On An On-Line TOC Analyzer In Pharmaceutical Applications
    Application Note: Preliminary Performance Study On An On-Line TOC Analyzer In Pharmaceutical Applications Total Organic Carbon (TOC) analysis is an effective technique for detecting and measuring the presence of organic contaminants in waters used throughout industrial processes, municipal water uses, and for determining residual concentrations of organic material on the surfaces of equipment used in the manufacture of active pharmaceutical ingredients. By Jeffrey Lane, Steve Skalski, and Gary Engelhart, OI Analytical
  • 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.

  • Dissolved Oxygen Measurement In A Wastewater Treatment Plant
    Dissolved Oxygen Measurement In A Wastewater Treatment Plant

    Breakdown of organic wastes entering a wastewater treatment plant is accomplished by using a biomass or blend of beneficial microscopic organisms, bacteria, and solids. This converts the non-settleable solids (dissolved and colloidal matter) into settleable solids, carbon dioxide, water, and energy.
