Wastewater Case Studies and Whitepapers

51. City Saves Big Money By Using Cloth Media Filters To Treat CSO Discharge 4/12/2019

    The City of Rushville, Indiana had to remedy a consent order filed in 2007 for its untreated combined sewer overflow (CSO) discharges that were polluting the Flatrock River, a violation of the Clean Water Act. The city originally planned to install a 1 MGD stormwater storage tank, but was approached by Aqua-Aerobic representatives with a pilot test proposal utilizing a new technology.

52. UV Disinfection And Dechlorination At Cottonseed Processing Facility In Texas 2/6/2024

    In this case study, learn how a cottonseed processing facility in Texas successfully prevented biofouling in their RO membrane filtration system by installing the HOD UV technology from Atlantium.

53. Use Of Pure Oxygen To Resolve Capacity And Odor Problems 7/27/2017

    The Escalon Industrial Waste Water Treatment Facility’s service area is seasonal and centered on tomato and pickle processing. The production season (roughly mid-July through mid-October) sees high hydraulic- and BOD loads that strain the facility’s capacity. During the high season highly variable BOD load depletes DO and causes permit violations and odor complaints. Praxair installed 4 X 15 HP Medium Velocity Oxygenation (MVO™ oxygenation system), with the ability to deliver up to 6 TPD of oxygen to supplement the existing aeration capacity at the facility.

54. Spotlight On Reclaimed Water Regulations: California 3/13/2024

    Technological advancements play a crucial role in shaping reclaimed water regulations, as new methods for treating and reusing wastewater emerge.

55. Acoustic Inspection As A Solution For Rural Water 8/28/2025

    To improve efficiency, a Virginia utility adopted acoustic inspection technology (SL-RAT) in 2018, enabling a shift to condition-based maintenance.

56. What Happens After The BMP Is Installed? 5/20/2009
    The demand for stormwater treatment is rising at an increasingly accelerated rate as the Environmental Protection Agency Regulatory demands become more stringent. These regulations have provided the way for emerging technologies to meet the environmental needs, from Land Based to proprietary products. By Jeffrey Benty & Dino Pezzimenti
57. FlexRake Bar Screens At 24+ Sites Around Houston Were Unaffected By Hurricane Harvey 9/11/2018

    Despite the destruction of Hurricane Harvey in August 2017, Duperon wastewater screening systems in the cities of Cuero and Refugio, Texas – approximately 150 miles southwest of Houston – were virtually unaffected by the storm. Duperon’s FlexRake bar screens, installed at both locations as well as dozens of other sites in and around Houston, remove objects like rags, paper, plastics, and metals to prevent damage and clogging of downstream treatment equipment. Both communities found essentially no damage to their wastewater screening equipment.

58. Fine Screening System: The More Intelligent Primary Clarifier 11/27/2018

    In the discussion about limited resources and energy saving in sewage treatment plants innovative sewage treatment methods are increasingly becoming a focal point. In Germany, there are about 1,200 sewage treatment plants which are designed for 10,000 to 50,000 PE, about one third of them have a sludge digester. Thus, there is a potential of about 800 sewage treatment plants that remains for a change from aerobic sludge stabilisation to processes with anaerobic sludge stabilization.

59. Outfitting The World's Largest And Greenest Wastewater Treatment Plant 10/15/2015

    The sprawling Blue Plains Wastewater Treatment Facility is the largest advanced wastewater treatment plant in the world, with a capacity to treat an average of 370 million gallons of sewage a day. Some $4 billion in recently completed projects and work now in progress are making the plant more efficient and taking its green operations to new levels.

60. Three Wastewater Treatment Issues That Can Be Improved With High-Purity Oxygen 2/17/2017

    Wastewater facilities in various industries face challenges in day to day operations. Some of these treatment issues can be addressed by incorporating high-purity oxygen into the wastewater treatment process. Below are three common wastewater treatment issues and how oxygen may help.
