Wastewater Case Studies and Whitepapers

31. What Private Utilities Need to Know About Nutrient Loading and Eutrophication 8/7/2025

    For private utilities, discharging wastewater isn’t a one-size-fits-all process. If your facility serves a resort, a golf course, a residential community, or a mixed-use development, you’re likely discharging into smaller, localized water bodies (creeks, ponds, wetlands), not large rivers or oceans. And while these ecosystems are beautiful they’re also incredibly vulnerable to nutrient loading and eutrophication.

32. Selecting The Right Blower For Reliability And Cost-Effective Operation 7/25/2022

    Edward Paro, Portfolio Manager Compressors & Aeration at Sulzer, offers advice on specifying blowers and how to optimize performance while minimizing costs.

33. Maximizing Speed And Accuracy In Microbiological Testing 6/18/2020

    A quality outcome is only as reliable as the components and processes used to create and test it. When it comes to municipal drinking water, food, beverages, wastewater effluent, and other industrial applications, having reliable microbiological testing reference materials to benchmark quality control (QC) processes is essential. Here are some important points to consider when establishing or managing QC programs.

34. 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.

35. Groundwater Replenishment System - Orange County, California 6/15/2009

    The full-scale advanced treatment system takes filtered secondary effluent from the neighboring OCSD treatment plant and converts it to water that exceeds all drinking water quality standards.

36. Maximum Security With The Space-saving SPIRALIFT® SLV 11/9/2020

    Due to the waste from the Northeast Correctional Facility, Alliance Water Resources, the wastewater treatment plant in Bowling Green, Missouri, was constantly having problems. The prison, which produces 300,000 gallons of water per day, was creating a deluge of problems for the pump station, including clogged and plugged pumps, excessive power draw and the need for continuous service and ultimate pump replacement. The inmates were flushing paper, jumpsuits, and all manner of debris – pretty much anything they could flush. It was costing the plant a lot of downtime and tons of money. Once the pumps started needing total replacements on a very frequent basis, costing the plant more than $30,000 each year, they knew they needed a solution.

37. DIC Corporation Unveils New SEPAREL Hollow Fiber Membrane Module For Decarbonation 10/19/2017

    At Aquatech 2017, Sun Chemical Corporation and its parent company, the DIC Corporation, unveiled two new SEPAREL® hollow fiber membrane modules for decarbonation. The EF-120-Q and EF-040P-Q modules extend the life of ion-exchange resins used in the production of pure and ultrapure water by utilizing a proprietary hollow fiber membrane that removes 1.7 times more Carbon Dioxide than any existing SEPAREL module.

38. Air Filter Maintenance: Impact On Efficiency And Machinery Health 5/29/2012

    In an ideal world, would we not want to eliminate air filters altogether? What keeps us from achieving this is foreign material, detrimental to air, which moves rotating equipment; meanwhile, the process that receives the air sometimes cannot tolerate it.

39. Case Study: Aerator/Mixer System Gives China WWTP Trouble-Free Performance 7/7/2007

    Aeration Industries International, Inc. is playing a key role in cleaning up water worldwide to help preserve the earth’s most precious resource, water. When the Chinese city of Lin An planned an expansion to their oxidation oval system, officials were looking for a new type of aeration system that would offer process performance and trouble free operation. The company's AIRE-O₂ TRITON process aerator/mixers were the ideal solution for the Lin An wastewater treatment facility.

40. Tackling Rising Energy Costs 6/21/2023

    Within the water treatment industry, aeration processes consume the most energy. However, costs for electricity are continuing to rise, even for large customers that are accustomed to negotiating lower than average prices.
