Traditionally, FRP duct has been the standard material for handling foul air exhaust in wastewater treatment plant odor control systems. Today however, as system longevity, overall fire safety, environmental footprint and ease of installation and maintenance play larger roles in system design specifications, WWTP's are increasingly turning to coated stainless steel for their odor control system needs.
As communities, municipalities and wastewater treatment facilities alike devote more and more resources toward mitigating hydrogen sulfide gas (H2S) as an industrial and environmental pollutant [1], the resultant foul-air systems and the materials from which they are constructed must be called into question.
We are entering a new age, one where people are realizing that it’s possible to meet and exceed business financial goals and to still make progress in preserving our environment. This concept is taking hold in new and diverse ways across many commercial and industrial spheres. It's known as the circular economy.
You’ll be hearing this phrase more and more as its influence grows, but what exactly does it mean?
Sludge dewatering is the process of removing as much water as possible from wastewater and sewage sludge. The output of this process includes untreated water that will continue to be cleaned and purified (before being released and reused), and biosolids with drastically reduced liquid content, volume and mass.
The reduced mass and volume of the biosolid end-product makes it far easier to store or transport, being both lighter and with a far smaller footprint. It is then either land applied as agricultural fertilizer or sent to a landfill.

Biosolids are a nutrient-rich organic material produced when sewage sludge is extracted from wastewater and treated with several processes, including one to reduce pathogens. It can have an organic matter content of up to 50% and is often used as an alternative to conventional fertilizer.

When odors from wastewater treatment facilities become problematic for surrounding communities, they have the potential to cause more headaches than simply an unpleasant smell. Depending on the severity of the foul air, locals may contact plant management to complain, or in more severe cases they may even reach out to local government or the media to make their complaints be known. If these odors begin to garner political or media attention it could hurt the reputation of the plant. Moreover, severe odors can impact job satisfaction and even the safety of on-site employees.
So, what can be done to control problem odors?

Fab-Tech Inc., will be attending the 91st annual WEFTEC Conference in New Orleans, joining nearly 21,000 registrants and 1000+ exhibitors from around the world.
This event is "recognized as the largest annual water quality exhibition in the world... providing unparalleled access to the most cutting-edge technologies in the field."
Today, savvy wastewater treatment plant owners, engineers, and managers are paying close attention to the potential risks and unforeseen costs of the materials that are being used in their facilities and systems.
One area where material consideration can have both immediate and long lasting impacts is in the odor control systems of a wastewater treatment plant.
When it comes to exhaust duct installation, some materials like FRP duct may require a deep investment of time, money, and specialized labor.
Wastewater treatment plants are sites where odorous and hazardous fumes are dealt with on a daily basis. As facilities face an ever growing list of water and air-quality issues with which to contend, advancements in vapor phase odor control technology have been sought to help mitigate many of these challenges and concerns.
This article examines some of the leading reasons why PSP® fluoropolymer coated stainless steel duct stands out as the preferred choice for wastewater odor control systems.

Wastewater odor control systems and vent pipe products not only need to contain foul air but also need to be highly corrosion resistant. For decades, wastewater treatment facility owners (and engineers) have faced a major pain point with plastic and FRP duct systems that degrade and need regular repair or replacement.
Compounding this pain is the fact that many plastic and FRP duct products are highly combustible. In the event of a fire, or gaseous ignition, such systems will likely be rendered useless if not completely destroyed. In short, wastewater facilities with these types of systems face the pain of higher fire insurance premiums; and those that self-insure face catastrophic losses.

It's always nice to discover that little advantage or edge-up which makes our lives easier, safer, cheaper, or more productive. It's even better when that advantage is not so little, and when it improves our lives across all categories!
This article takes aim at four big advantages of PSP® coated stainless steel duct and how it surpasses FRP duct in quality, safety, cost, and convenience.
When it comes to installing odor control systems in wastewater treatment facilities, one of the many design considerations to resolve is whether to use fiberglass reinforced plastic (FRP) or coated stainless steel duct.
Historically, FRP duct has been the more common choice from a cost perspective, but increasingly savvy WWTP owners and engineers are recognizing that there are hidden costs and strict rules and regulations that come with a decision to use FRP materials.
Many modern wastewater treatment facilities are moving away from traditional fiberglass reinforced plastic (FRP duct) and employing PSP® odor control exhaust duct instead. Through informed research, facility owners and engineers are learning that PSP® delivers superior performance, superior labor savings, superior safety, and lower maintenance than FRP duct.

Over the next 6 years, the global market for wastewater treatment equipment and chemical products is expected to grow by more than 138 billion dollars (1). This enormous increase in spending will be driven by shrinking clean water supplies, increasing demand, growing population densities, and the growth of industrial applications beyond current water treatment capacities.

The DC Water and Sewer Authority (Blue Plains) is the largest wastewater treatment facility in the world. DC Water utilizes some of the most advanced treatment systems available to provide water and wastewater treatment services to more than 600,000 local residents, another 1.6 million people from neighboring Maryland and Virginia, 17.8 million annual visitors and 700,000 people that work in the DC area.

In a previous article about wastewater treatment plant odor control, we examined the role of wet scrubber systems in the mitigation of foul and hazardous fumes associated with hydrogen sulfide gas (H2S). In this installment, we turn our attention to three additional vapor-phase odor control technologies.

Wastewater treatment plants around the world use various processes to treat wastewater from homes and businesses. Recently, odor control has become an increasingly pertinent issue for WWTP owners, architects, engineers and design-build companies. As population densities increase and residential zones expand around wastewater treatment facilities, public tolerance for foul odor seems to decrease proportionately.
This article targets three stages of the wastewater treatment process where PSP® odor control vent duct can be applied to help alleviate public outcry and improve general air-quality.
