Ovivo Clarifiers
What model of Clarifier
will satisfy your needs?
- Primary Sludge
- Rapid Return Secondary Sludge
- Column & Bridge Supported Mechanisms
- Sludge Thickening










There are several designs of clarifier available from Ovivo. These can be broken down into the following catergories to help you select the type of mechanism
Mechanism Support:

Column Supported
Column supported clarifiers are typically used, cost effectively, in tanks from 40 ft and above.

Bridge Supported
Bridge supported clarifiers are typically used, cost effectively, in tanks from 50 ft diameter and below.
Type of Sludge Collection:
- Spiral Bladed Clarifier – Rapid return sludge design.
- Uses spiral shaped blades to return sludge faster for fresh biosolids.
- Suction Duct Header Clarifier – Rapid return sludge design.
- Uses a horizontal header to return sludge faster for fresh biosolids.
- Suction Tube / Organ Pipe Clarifier – Rapid return sludge design.
- Uses multiple tubes to return sludge faster for fresh biosolids.
- Standard Plow Blade – Typically used for primary sludge collection.
- Also commonly used in small secondary sludge clarifiers.
- Gravity Thickener – Diagonal plow blades with pickets to assist in thickening the sludge.
- Used to thicken sludge for further processing.
