The Jetting Dredge – Slurry Management Systems
Capable of operating in many hazardous environments, the Jetting Dredge is popular in both the mining and abrasive industries. However, this suitability makes it equally ideal for use in locations such as quarries, sand and aggregate plants.
Through the combination of suction and agitation, along with constant movement of the unit through a pond or tank, allows effective and efficient removal of semi-compacted mineral slurries. The resulting slurry is then ready for delivery to the next processing stage at your required rate.
Our Jetting Dredge is ideal for use in poly, concrete or clay lined ponds. By removing the need for any cutter heads and augers, the result is a suction head that can physically contact the liner, and do so safely, providing maximum lining protection.
Some common usage applications include:
- Municipal Wastewater
- Heavy Industry
- Oil and Gas
- Ponds can remain on-line and operating throughout the process
- Quiet and environmentally friendly
- Suitable for scheduled maintenance in addition to major slurry removal projects
- Flexible designs available for difficult site conditions
- Suitable for most pond linings
- Cost effective operations
- Easy commissioning, decommissioning and cleaning
Performance Metrics and Pricing
UAT will generally build a Jetting Dredge to match customer needs. To do this we match a surface mounted jetting pump with a 4 or 6 inch primary dredge pump. The primary dredge pump that we select will best suit the sediment for the job.
A typical Jetting Dredge can deal with 80 to 100 m3 per hour within a 150 metre radius. Volumetric densities of 20% to 40% are achievable.
As these are custom built to suit a specific purpose and components must be carefully selected to meet UAT standards for quality, longevity and slurry requirements.
