STSR - Vivianite Remover and Preventer

• Product recirculations & standstill soaks
• Low-pressure sprays
• Foaming application
• Vivianite can be prevented by dosing our products typically between 30-90ppm.

Replacing Equipment, Grinding or Hydro-jetting:

1. A lot of downtime
2. Labor intensive (High costs!)
3. If any vivianite remains, will grow and accumulate much faster

Using Hydrochloric Acid or other acids to remove vivianite scale:

1. Highly corrosive
2. Highly Hazardous
3. Leads to damaged equipment

Vivianite is a crystal formation that can form in wastewater treatment plants due to the addition of irons salts such as Ferric Chloride to control orthophosphate and H₂S. It tends to be a blue, green or purple color.

Vivianite, like struvite, can cause a lot of problems for WWTPs as it can develop in pipelines where it can cause:

• Reduction of the flow rates
• Shaking of equipment
• Heat transfer lost
• Clogged pumps and lines
• Require maintenance in other areas and equipment, etc.
• Vivianite tends to be harder to remove compared to Struvite due to its composition.

Vivianite precipitation causes crystal formation issues in several areas of a wastewater treatment plant and other operations, including:

• Anaerobic digesters
• Places where there is high kinetic energy (high turbulence)
• Pipe connections – especially elbows
• Pumps are a prime location
• Valves
• Aeration assembly
• Internal pumping components
• Plant overflow box of the anaerobic digester
• Wastewater Sludge transfer line
• Plant Centrifuges
• Rollers of the Belt Press
• Heat exchangers

• Environmentally Friendly
• Non-Corrosive to Steel and Unbroken Skin
• Safe to Handle
• Easy to use, with many applications
• Cost-Effective, saving you time, money and leaving your operation free of Vivianite

Product is available in:
