In 2016 Hillsborough County Public Utilities, a forward thinking organization, initiated the first direct potable reuse pilot project in Florida. In its efforts to utilize 100 percent of its reclaimed water, the progressive utility created a successful program to effectively suspend surface water discharges. The pilot project validated direct potable reuse, which is now a key initiative for many central Florida utilities due to the implementation of the Central Florida Water Initiative requiring the additional utilization of reuse water resources.

By providing valuable data and insights, pilot tests enable facilities to make informed decisions, optimize their operations, and mitigate risks associated with new technologies.

Integrating aeration and mixing through jet aeration enhances oxygen transfer, improves process control, and significantly lowers power consumption—especially when upgraded with advanced Slot Injector technology.

The Cape Fear Public Utility Authority (CFPUA) in North Carolina engaged in a capital improvement project to help address their aging infrastructure.

When developing water or wastewater treatment processes for entirely new applications or modifying existing processes to accommodate changing water characteristics or regulatory discharge requirements, understanding capital investment, operating cost, and long-term performance is critical. Here are several ways to view pilot-plant or lab-scale testing as viable approaches to better outcomes with lower risks.

In the constant flow of drinking water and wastewater treatment systems, operators have precious little time to waste. When unexpected changes arise, maintaining balance throughout the process is key.

Knowing that aeration requirements consume 50 to 60 percent of a wastewater treatment plant's (WWTP) energy bill is one thing. Knowing exactly how and when to tweak aeration output to optimize activated sludge process efficiency with minimal energy waste is an entirely different story.

Accurate dechlorination control requires monitoring all residual oxidants that threaten membrane integrity. Total chlorine analysis provides the necessary precision at ultra-low levels, ensuring comprehensive protection against oxidative damage while maintaining reagent stability during intermittent system operations.

Municipal wastewater treatment plant operators face significant challenges from a surge in clogs. Wipes that have been marketed as flushable, but don’t necessarily break down like toilet paper, are increasingly ending up in the waste stream. The proper mechanical solutions can help mitigate the problem and make operators’ lives easier.

Conventional activated sludge treatment for wastewater is becoming increasingly problematic over time. Not only does the process require significant amounts of energy, which drives up operating expenses, but utilities are under mounting pressure from the U.S. EPA to go green.

In recent years, various perflorinated chemicals (PFCs) have come under increasing scrutiny due to their presence in the environment, in animals, and in human blood samples. There are two major classes of PFCs: perfluoroalkyl sulfonates such as perfluorooctanesulfonic acid (PFOS) and long chain perfluoroalkyl carboxylates such as perfluorooctanoic acid (PFOA) and perfluorononanoic acid (PFNA).

The textile industry is a water consumption intensive industry. Water is utilized for cleaning the raw material, and for the different steps in the textile dyeing process. Due to the effects of water scarcity and stricter environmental regulations, the cost of fresh water utilization has increased worldwide.

Successful aquaculture corporations know that there are many variables that need to be accounted for in order for the bottom line to be “in the black”, let alone grow annually by 10-20%.

A water purveyor was in urgent need of a chemically resistant flow instrumentation with a long life of service that allowed reliable and long-term stable dosing of the sodium hypochlorite solution.

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

Lack of sufficient straight pipe run made it impossible to successfully apply the preferred magnetic flow meter (magmeter) to accurately measure the flow of raw sewage.

The most common level application in the water and waste water industry is the infamous wet well. With its line-of-sight measurement technology, rugged sensor, narrow laser beam and virtually nonexistent maintenance requirements or on-site calibration, ABB’s LLT100 laser level transmitter answers most concerns related to wet well level measurements and makes it easy to calculate what could amount to a substantial return on investment.

The QuEChERS (Quick-Easy-Cheap-Effective-Rugged-Safe) sample extraction method was developed for the determination of pesticide residues in agricultural commodities.

Being able to accurately measure both the quantity and rate of water passing through a water distribution system is crucial to gain an informed understanding of overall efficiency. As such, achieving a measurement that is exact as possible can have a significant impact on key areas. This includes supply planning, maintenance, resource deployment, leakage detection and the overall environment.
