GHOST Inline Sludge Thickeners

Compact. Continuous. Geometry-driven thickening.
 
The GHOST™ Inline Sludge Thickeners are compact, high-efficiency systems designed to increase sludge solids concentration while maintaining fluid-like behavior for downstream transport and processing.
 
Unlike conventional gravity belt thickeners or rotary drum thickeners, Ghost Inline Thickeners operate in a fully enclosed, inline configuration, reducing sludge volume without converting it into a difficult-to-handle solid phase.
​
The result: less water, less volume, same pumpable sludge.
​
How It Works
Sludge enters the Ghost Thickener as a low-solids stream and passes through an internal separation geometry that concentrates solids while continuously releasing centrate.
 
Thickened sludge exits at higher solids concentration, while clarified centrate is discharged separately.
​
This controlled inline process increases solids concentration and reduces total sludge volume without requiring large footprints, open tanks, or gravity-based separation.
​
Key Advantages
Performs the function of a gravity belt thickener or rotary drum thickener
Requires up to 75% less space than conventional thickening technologies
Fully enclosed, inline operation
Maintains sludge in a liquid, pumpable state
Continuous operation with minimal civil works
Ideal for retrofit and space-constrained facilities
​
Operational Value
Ghost Inline Sludge Thickeners are especially effective for facilities that haul sludge between treatment plants or off-site for further processing.
By thickening sludge before transport, facilities haul solids instead of water, reducing hauling frequency, fuel costs, and overall operating expenses — every day, on every load.
