Belzona® Clears Clarifier Problem

 
 

Industry:

Water / Wastewater (WATR)

 
 

Application:

Tanks and Chemical Containment Areas (TCC)

 
 

Customer Location:

Waste Water Utility, Oklahoma

 
 

Application Date:

March, 2007

 
 

Application Situation:

The aluminum shield on the clarifier extends 16 inches below the water line. This is the only one serving this small city.

 
 

Problem:

50% of the shield had been eroded away due to corrosion at the water line. A new skirt from the manufacturer would cost over $15,000 and take unduly long to install.

 
 

Products:

Belzona® 3921 (GSC Conditioner)Belzona® 5811 (immersion Grade)

 

Substrate:

Aluminum

 
 

Application Method:

Abraded new aluminum panels and coated with Belzona® 3921 and Belzona® 5811 in accordance with Belzona Know-How System Leaflet TCC-5. The panels were then bolted to the sound skirt eliminating need for complete replacement.

 
 

Belzona Facts:

The city did this repair using $500 of Belzona and $1,000 in metal and supplies. It also took them only 1 day versus more than a week to replace the whole shield.
