PSP® Exhaust Duct Carries Proven Performance And Cost Advantages

PSP stainless steel duct.pngWastewater treatment plants (WWTPs) are sites where corrosive, flammable, and toxic chemicals are used and generated on a daily basis. As facilities are faced with an ever growing list of chemical pollutants and water and air-quality issues, advancements in fume exhaust duct technology have been sought to help manage 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 WWTP fume exhaust applications.

1) Durability

To meet today's standards, WWTP vent pipe systems must be designed to handle not only a witches-brew of hazardous byproducts and chemical compounds, but also to stand up to extreme weather and environmental conditions and continue to perform 24/7 without issue. 

With its robust stainless steel construction, PSP® exhaust duct does not burn, weather, collapse or leak. Also, according to published data, fluoropolymer coated stainless steel far surpasses other materials in chemical resistance and durability. 

Its proprietary fluoropolymer barrier coating has been tested in over 400 chemical applications and proven superior to both FRP duct and plastics when tested for corrosion resistance, chemical concentration tolerance, and upper temperature limit.

2) Lifetime Cost 

Given its performance and durability, PSP® provides WWTP owners with tremendous savings in the form of eliminated maintenance, repair and replacement costs over the lifetime of the system.

When performing a vent pipe system cost analysis, it's not enough to simply compare the per-foot expense of different system materials, it's also critically important to consider what hidden ownership costs may arise. Such considerations should include:

  • the total installed cost of the system including any special or custom labor requirements
  • any necessary enhancements like sprinkler systems and graywater handling upgrades
  • ease of adaptability to new or existing systems 
  • lifetime maintenance, routine protective coating applications (as with FRP duct), and insurance costs
  • the longevity and capacity of the system to meet future regulatory requirements
  • and even the cost and ease in which the system may be disposed or recycled in an end-of-use scenario

3) Safety

Since virtually every process within a WWTP has the potential to produce and release hazardous vapors, workplace safety and environmental safety should rank high on every fume exhaust system consideration list.

After all, airborne hydrogen sulfide is the most prevalent odorous compound present at wastewater treatment sites. This objectionable gas is not only odorous, but can be very deadly.

The United States Department of Labor - OSHA warns "[H2S] is a highly flammable, explosive gas, and can cause possible life-threatening situations if not properly handled. In addition, hydrogen sulfide gas burns and produces other toxic vapors and gases, such as sulfur dioxide."

It comes as no surprise then, that wastewater treatment engineers and operators are extremely diligent in their search for worry free, maintenance free, long-lasting, and dependable fume exhaust systems and materials.

With its superior performance, safety, reliability, and cost advantages, PermaShield Pipe (PSP®) meets all of these criteria and more.
