Application Situation

This is a large wastewater plant that processes approximately 80% of the waste generated by two populated municipalities in the GTA. They had several of these dewatering centrifuges and over the years they had been successfully coating them with Belzona.

Application Method

The steel substrate was prepared to and in accordance with SSPC-SP 11, Bare Metal Power Tool Cleaning. This method of surface preparation was chosen as the plant was in operation and abrasive blasting was not an option. Once the substrate was prepared, Belzona 1111 was applied as a stripe coat to smooth out any defects, joints and seams. Belzona 1341 was then applied in two coats of alternate colors

Belzona Facts

Belzona 1341 has proven successful in protecting the equipment from erosion-corrosion but also in reducing the scaling and improving the efficiency of the equipment.
