Self-Contained Storage Silo

Self-Contained Storage Silo

This project was a self-contained storage silo designed to store powdered activated carbon for a dissolving system used to treat industrial wastewater. At 2,750 cubic feet, the tank measured 12’-0” in diameter and 48’-0” high. While the tank and its skirt were fabricated from carbon steel, all the customer-provided components installed by Southern Metal Fabricators were 316 stainless steel. After being inspected for quality, the final product was assembled to the fullest extent possible and shipped to Tennessee, where it was installed by the client.
