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.
The measured surface pH can then be used to correlate corrosion rate
and subsequenity, remaining years of useful life of concrete structure.
Pumping and conveying of wastewater from end user through the collection system towastewater treatment plants can result in negative conditions including gas binding, blockages associated with fats, oils and greases (FOG), and system corrosion. There may be other contributing conditions, but these factors appear to be the greatest contributors to O&M costs including energy consumption, maintenance costs, and Sanitary Sewer Overflows (SSOs).
A collection system line is a unique conveyance system. The transfer of wastewater can result in the release of gases such as O2 ‒ Oxygen, CO2 ‒ Carbon Dioxide, N2 ‒ Nitrogen Gas, H2S ‒ Hydrogen Sulfide, CH4 ‒ Methane, VOCs ‒ Volatile Organic Compounds, and VOSCs ‒ Volatile Organic Sulfur Compounds among others. Some of these gases are drawn into the system through pumping and ventilation, while others are generated within the system either chemically or biologically. These gases can result in the development of gas binding in the system, especially with the utilization of calcium nitrate, as well as contribute to odors and corrosion.
