Suction Dredge
The suction dredge (previously known as the SludgeRat) can be adapted for various rates and volumes of delivery, head pressure and distance to dewatering or transport systems or equipment.

The Suction Dredge – Sludge Removal Systems
Our Suction Dredge range is primarily for soft sludge wastewater plants. The suction action in combination with constant movement of the unit through a pond or tank, allows for effective and efficient removal of non-compacted / soft organic sludges.
Resulting effluent is then ready for delivery to the next processing stage at the required rate. For the removal of these organic bio-solids, a single unit is best suited to impoundments typically up to 40,000 square metres in surface area and up to 3 to 4 metres in depth.
Not only is it possible to modify the Suction Dredge on request, but we can also multiply the units in order to suit an even wider range of scenarios.
Some common usage applications include:
- Utilities and Water Treatment Plants
- Agribusiness – Feedlots, Piggeries and Dairies
- Abattoirs
- Industry Pulp and Paper Mills
- Recreational Water Bodies
Benefits
- Impoundments can remain online and operating during sludge removal
- Quiet and environmentally friendly
- Suitable for both management and major sludge removal projects
- Flexible designs for difficult site conditions
- Suitable for a majority of pond linings
- Cost effective operations
- Easy commissioning and decommissioning
- Corrosive resistant materials

Remote Operation
With the utmost safety in mind, control of the unit it maintained via an Operator from a safe land based location.
Remote controlled height adjustment of the primary sludge pump and suction head enables fast and efficient blending of solids and liquids (particularly if coupled). This enables adjustable reactive pumping based on the discharge from the pump.
