Ballast Decanter

The Vens ballast decanter draws clear liquid from just below the surface of a tank or lagoon. A floating weir box, held by twin pontoons, rises and falls with the level, and a pivoting discharge pipe carries the decanted water to the outlet.
Drawing from below the surface keeps floating scum and settled sludge out of the discharge.

Vens has more than 10,000 installations. Every unit is designed by engineers who studied at MIT, Stanford, Cornell, the IITs, Arizona State University and the University of Cincinnati and have worked in the industries that use this equipment, so it is sized for the job, built in the right materials and designed to proper factors of safety.
