Corrosion's Primary Cause:

Sulfide gas is converted to corrosive sulfuric acid on infrastructure surfaces.

The acid dissolves concrete and metal on surfaces inside sewers and wastewater treatment plants, throughout the entire treatment and delivery process. Acidic Corrosion is prevalent in virtually every stage of the process – in your Collection System, your Headworks, in Primary and Secondary Clarifiers, in your Digesters, and in the Disinfection Processes. Corrosion is a system-wide problem, requiring a system-wide solution.

 

So, why add to the Problem,
rather than Adding the Solution?

Adding or creating ALKALINITY is the most direct and effective way to neutralize the problem of excessive acidity in our water and wastewater infrastructure. However, many common treatments either provide no acid neutralization, or actually consume alkalinity in their chemistry.



Thioguard® provides the greatest power to neutralize acid over long infrastructure distances while providing additional benefits to your WWTP plant's biological treatment processes. The chart above compares the alkalinity per gallon, among the most commonly used treatment options.




Adding to the Lifespan of your Infrastructure -
Preventing Further Corrosion:

In an acidic environment (pH=2), corrosion is rampant, tearing through 2" of concrete in as little as 8 years. When effective surface pH=4, similar corrosion levels are pushed out to 50+ years.

 

The Addition of THIOGUARD® Boosts liquid & SURFACE pH levels, PREVENTING the acidic conditions that speed up
and encourage corrosion.

By reducing the acidity in your system, you'll reduce corrosion dramatically, in some cases by as much as 100X, when compared to other treatments. Thioguard® is typically added through a single Feed Unit, and provides "corrosion-controlling" benefits throughout your system, from collection system source to treatment plant discharge.

The measured surface pH can then be used to correlate corrosion rate and subsequently, remaining years of useful life of a concrete structure.

The use of Thioguard® by direct addition has been demonstrated to elevate surface pH from a highly corrosive pH=0-2 up to a more desirable range of pH=5-9.

Thioguard is the ONLY commonly used product that has a direct mechanism to PREVENT CORROSION. The benefits of adding Thioguard® to your treatment processes are not limited to the prevention or reduction of corrosion. You will also benefit from a reduction in the formation of sludge - significantly reducing your handling and transportation costs. The benefits are numerous and system-wide, making Thioguard® the Practical Choice for your system.
