All Wastewater Case Studies
Real Projects. Proven Results. Lasting Impact.
Our case studies highlight innovative wastewater treatment solutions developed for municipalities, industries, and private clients. Each project demonstrates our commitment to reliability, efficiency, and environmental stewardship — from reducing nutrient loads to reclaiming water for reuse.
Our wastewater solutions are available today and fully supported by a dedicated technical team — from design and commissioning to long-term operation and optimization.
We believe every drop of water recovered is a step toward a cleaner, more resilient world.
Toxic Hit Recovery at a Mechanical Wastewater Treatment Plant
Wastewater treatment utilities receiving inputs fromindustrial and anthropogenic sources are highlysusceptible to toxic waste inputs. Toxic loads are oftensporadic and can be extremely devastating to thebiomass in treatment facilities.Figure 1. Toxic impacts on a...
Toxicity Treatment in a Wastewater Lagoon System
Municipal wastewater lagoon systems are susceptible to toxic waste poisoning. Toxic loads from residences and businesses are sporadic and difficult to mitigate. When toxicity levels are high in wastewater lagoons, the biological treatment process is inhibited due to...
Toxicity Treatment in a Municipal Wastewater Lagoon System
Wastewater lagoon systems often experience biological upsets when toxic loads are introduced. Specifically, the chemicals used in illicit drug manufacturing can cause significant harm to the microbial communities in surface waters.1 Municipal lagoon systems are...
Toxicity Treatment in a Facultative Lagoon System
The biology in wastewater lagoons can be significantly impacted by toxic substances introduced from illicit drug manufacturing. Surface waters contaminated with amphetamines, and the chemicals used to manufacture them, are known to suppress aquatic life, including...
Toxicity Treatment in an Oil Refinery Aerated Lagoon System
In need of a recovery plan for their wastewatertreatment system, an industrial oil refinery in NewMexico used BioLynceus® to restart their biologicaltreatment after a toxic hit. The refinery was processing50,000 barrels of crude oil a day.Figure 1. Large oil refinery...
Toxicity Mitigation in an Industrial Sequencing Batch Reactor
Managing toxic loadings at industrial wastewater treatment facilities can be challenging. Influent from food processing industries can introduce harmful cleaning products. The book Wastewater Bacteria, by Michael Gerardi, explains cleaning chemical surfactants can be...
Startup of a Fixed-Film Activated Sludge Process
Establishing a functional biological community for wastewater treatment is essential when starting a new plant. Monitoring the growing biology during a startup provides the insight plant staff need to adjust operations to achieve a high treatment efficiency....
Startup of a Moving Bed Biofilm Reactor
National parks attract millions of visitors each year.Increasing seasonal traffic experienced by theseestablishments can overload the wastewater treatmentinfrastructure leading to treatment inefficiency and,eventually, structural replacement. When starting up anew...
Startup Mechanical Plant After Failed Activated Sludge Seeding
Choosing an appropriate seeding method for wastewater operations can have a significant impact on biological treatment efficiency. Activated sludge is traditionally used to seed new treatment systems and supplement others that need bioaugmentation. A common issue in...
Start-Up of a 6.7 MGD Anaerobic Digester at a Sugar Refinery
Halfway through a sugar beet processing campaign(September through May) a Midwest refinery noticedsomething was wrong with their wastewater processingsystem. The plant discharge was within limits for their NPDESpermit parameters, but the chemical oxygen demand...
Nitrification with ProBiotic Scrubber® N in an Activated Sludge Plant
An effective activated sludge system has the capacity to remove ammonia from influent wastewater via nitrification. Several factors impacting efficient ammonia and nitrite oxidation in wastewater treatment include, temperature, and abundance of carbonaceous and...
Nitrification Bioaugmentation in an Activated Sludge Process
Augmenting wastewater processes with culturesof nitrifying bacteria can increase abundance andnitrification efficiency correspondingly. Additionally,implementing organic matter degrading microbiologyin a system can increase the time available for bacteriato oxidize...
Nitrification Treatment in an Aerated Lagoon System
Municipal Lagoon systems are often challenged withfacilitating nitrification. Nitrifying bacteria are responsiblefor removing ammonia from wastewater. These organismsare generally in low abundance in lagoon processes for a fewreasons; [1] nitrification is an...
F:M Stability in a National Park Wastewater Network
The F:M in the wastewater treatment network at aNational Park in Wyoming was optimal from July –October. There was consistent organic carbon loadingduring this time from tourist activities. However, whenthe park closed for the winter, the biomass declineddue to...
F:M Treatment with Candy Carbon® at an Activated Sludge Plant
Many wastewater systems experiencing high infiltrationand inflow (I&I) have issues with hydraulic overloadingwhich impacts biomass stability. I&I can impair thecapacity of the wastewater collection system andwastewater treatment infrastructure.1Increased flows...
F:M Stabilization at a Mechanical Wastewater Treatment Plant
Wastewater treatment plants receiving inconsistentinfluent loads are often challenged with maintainingan effective biological treatment. Many of the keymicroorganisms in wastewater processes are dependenton organic substrate to grow and divide. When influentflows are...
F:M Stability in a Sequencing Batch Reactor
In many resort towns, the influent loads to thewastewater treatment system are highly variablethroughout the year. During the tourist seasons there isan abundance of wastewater to sustain the biomass attreatment facilities, but when the transient populationleaves,...
F:M Treatment in an Activated Sludge Plant
Wastewater systems located in regions with high annual precipitation, such as the Pacific Northwest, are prone to experiencing biological washouts due to high infiltration and inflow (I&I) from collection systems. I&I can critically disrupt the biological...
Candy Carbon® Denitrification in an Activated Sludge System
For many municipal wastewater treatment facilities, removing inorganic nitrogen to permitted discharge levels is a challenging requirement. Without the role of biological nutrient removal (BNR) in treatment systems, effluent wastewater will have high concentrations of...
