Positive Feedback On Belzona® Application Of A Secondary Clarifier



Water / Wastewater (WATR)



Tanks and Chemical Containment Areas (TCC)


Customer Location:

Water and Wastewater Treatment Plant, Ontario, Canada


Application Date:

October, 2011


Application Situation:

Secondary clarifiers.



The secondary clarifiers at the Water Pollution Control Center were pitted and deteriorated due to chemical attack from the biological treatment process.



Belzona 4131 (Magma-Screed)
Belzona 4911 (Magma TX Conditioner)





Application Method:

The tank was power washed and allowed to dry. Pits, cracks or holes were conditioned with Belzona 4911 and then filled with Belzona 4131 using a trowel. Once repaired, Belzona 5811 was applied to the entire internal part of the tank with rollers and brushes.


Belzona Facts:

Belzona helped get the tank back in production, helping the entire city of Sarnia. After 6 years, we received feedback from the Maintenance Mechanic of the facility: “Belzona 5811 has been holding very well and will contact the city about budget to move forward to coat the rest of the secondary tanks with Belzona solutions”.
