During winter in the Northern United States we experience icing problems with our clarifier’s conventional scum collection system and have to lock out the skimmer.  If we don’t lock out the skimmer it is bent during heavy icing conditions. Is there a better solution?

Ovivo’s “full trough skimmer” is a full radius (the space between the feedwell and the scum baffle) scum trough and scum skimmer system. The skimmer system is neoprene curtain hanging from a rotating cantilever support beam. With two skimmer arms, the entire clarification surface between the feedwell and scum trough is swept into the radial scum trough twice per mechanism revolution. Because the neoprene wiper merely hangs from the cantilevered support, the skimmer will travel over any ice which has formed on the liquid surface.
