Industrial & Environmental Concepts introduced clarifier and tank covers in custom designs as affordable and durable alternatives to aluminum, steel and fiberglass domes at WEFTEC 2018. They can be used on any tank where rainwater, temperature loss or odors need to be managed.

The Flexible Clarifier Covers, offered in gray or green, can be used on clarifiers and tanks of all sizes. They are made of industrial-grade, UV-protected geomembrane and have an expected service life of 15 to 20 years with minimal maintenance. Each cover is custom designed for local wind, rain and snow load conditions.

A stainless steel tensioning system distributes the load evenly around the tank circumference. If large equipment needs to be installed or removed, the cover typically can be disassembled and removed in half a day.

The covers weigh significantly less than hard domes. Custom designs give operators numerous options viewing windows, pipes, venting, sampling ports and scum beach access, along with many possible entrance access designs. The covers are anchored with industrial-rated stainless steel ratchets and stainless steel hardware. Gas-tight and semi gas-tight options are available.
