WASTEWATER CASE STUDIES AND WHITEPAPERS

  • White Paper: Water Reuse Strategies: Steel Industry Case Studies

    The steel industry has historically presented challenges for effective water treatment because it is a high water user and the applications may involve high heat, critical noncontact cooling, direct contact cooling, high suspended solids waters, oil and grease contamination, and complicated cascading. By Dave Christophersen, Veolia Water Technologies

  • Royal Environmental Systems And Water Tectonics Design State-Of-The-Art Stormwater Treatment System Located 20 miles east of Seattle,Washington, Redmond is home to 50,000 residents and many high-tech and biomedical companies, including Microsoft.

  • The Good And Bad Of Wastewater Instrumentation: Pros, Cons, And Opportunities
    The Good And Bad Of Wastewater Instrumentation: Pros, Cons, And Opportunities

    Instrumentation is heavily pushed to achieve efficiency, but it only works when you use it correctly – and many utilities don’t.

  • Wastewater Plant Cuts Mechanical Aeration Run Time With Solar-Powered Circulation Technology In the Buckeye State, the village of St. Henry, OH, is bucking the trend of many rural farming communities. Instead of losing residents and local businesses to bigger cities, this community is growing. Local industries such as turkey processing are expanding as well. By: Michael Christensen, SolarBee, Inc.
  • Z-88® Radium Treatment Process - City Of New Underwood, South Dakota Case Study

    This radium removal pilot study was conducted for the City of New Underwood, South Dakota. New Underwood’s water system contains concentrations of radium and gross alpha in excess of the Maximum Contaminant Levels (MCL).

  • White Paper: Filtration Is Key To Efficient Wastewater Management
    White Paper: Filtration Is Key To Efficient Wastewater Management

    Wastewater can be defined and handled in any number of ways, from industrial process water slated for return to the environment, to reclaimed irrigation tailwater used to water crops downstream, to state-of-the-art toilet-to-tap projects. By Amiad Water Systems

  • White Paper: What Happens After The BMP Is Installed?
    White Paper: What Happens After The BMP Is Installed? The demand for stormwater treatment is rising at an increasingly accelerated rate as EPA regulatory demands become more stringent. These regulations have paved the way for emerging technologies to meet environmental needs. With new product developments comes the need for testing and performance verification. Once the demands for verification are met and local regulatory agencies have accepted the practice, these practices can start to be specified and installed to help clean our stormwater runoff. But we should be asking ourselves a series of other questions. By Jeffrey Benty and Dino Pezzimenti
  • Greater Lawrence SD Chooses Headworks® Mahr® Bar Screen Upgrade
    Greater Lawrence SD Chooses Headworks® Mahr® Bar Screen Upgrade

    The Greater Lawrence Sanitation District is responsible for building, maintaining, and operating a system of sewage collection and disposal for over 130,000 people in five communities in Essex County. Established in 1977, the plant operates on the banks of the Merrimack River approximately 24 miles from Boston, in the northeastern part of Massachusetts.

  • Evidence Of A Critical Velocity In Underflow Baffle Design For Floatables Control In Combined Sewer Overflows (CSOs)

    Underflow baffles have gained in popularity over the last few years as a viable mean to intercept floatables in Combined Sewer Overflows (CSOs). This has happened in consideration of the extremely low application cost of the solution although the efficiency of underflow baffles has never been clearly proven

  • How To Buy Right, Not Cheap When It Comes To Solids-Handling Pumps

    Companies using solids-handling pumps as part of their processes know that even though the pumps are typically moving trash and other waste products, the type of equipment used can be a huge business decision. Most applications warrant more attention than simply choosing the first pump that pops out of a catalogue. By The Gorman-Rupp Company

  • Disinfection And Emerging Contaminant Removal With HyDOZ®
    Disinfection And Emerging Contaminant Removal With HyDOZ®

    In the summer of 2012, BlueInGreen partnered with a facility in Arkansas to study disinfection of wastewater and removal of emerging contaminants of concern (ECC) by utilizing dissolved ozone. The plant has a firm capacity of 12 MGD and includes primary clarification, activated sludge, secondary clarification, and sand filtration prior to the existing UV system.

  • 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.

  • Underground Treatment Of Airport Deicing Fluid
    Underground Treatment Of Airport Deicing Fluid While keeping air flight safe, airports and airlines are also obliged to clean up after themselves and protect nearby streams and water bodies. And due to increasing chemical usage and looming regulations, some airports will need to invest in significant infrastructure upgrades to capture and treat stormwater contaminated with deicing fluid. By Scott Wallace, P.E., President, Naturally Wallace Consulting and Mark Liner, PE, Senior Engineer, Naturally Wallace Consulting
  • Dissolved Oxygen Measurement
    Dissolved Oxygen Measurement

    One of the most important measurements in the determination of the health of a body of water is its dissolved oxygen content. The quantity of dissolved oxygen in water is normally expressed in parts per million (ppm) by weight and is due to the solubility of oxygen from the atmosphere around us.

  • 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

  • Chlorine Measurement In Wastewater And Regulated Discharge Requirements
    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.

  • Wastewater Treatment Facility Complements On-Line Monitoring With Automated Control
    Wastewater Treatment Facility Complements On-Line Monitoring With Automated Control

    The Minnesota River Valley Public Utilities Commission (MRVPUC) provides wastewater treatment for the City of Le Sueur and the City of Henderson in south-central Minnesota. A significant factor facing the utility is the highly varying phosphorus load that challenges operators to meet the utility’s annual average discharge limit of 1.0 mg/L total phosphorus.
