Buoyant Floating Truss Digester Cover

ClearStream- Buoyant Floating Truss Digester Cover is a primary digester cover preventing a large scum blanket since the cover is in direct contact with the sludge to reduce liquid area exposed. This cover is most effective when sludge levels vary significantly and in conditions where extreme foam occurs.  The ballast blocks are located in the attic space where the attic space acts as natural thermal insulation.

A truss design is more expensive than comparable beam covers and the attic space collects condensation which will need to be removed periodically.
