Supernatant Decanter

The Vens supernatant decanter draws the clear liquor that forms above settled sludge in digesters and thickening tanks. A floating ring carries the weir cup, and a telescopic pipe lets the draw-off point follow the liquid level.
This keeps the outlet in the clear layer and avoids drawing sludge into the return line.

Sludge thickening and holding tanks
Effluent tanks with variable levels
Industrial process tanks
Tell us the tank depth and draw-off rate and we will size the decanter.

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.
