Recirculation Waste Removal
Product: Geotube® Dewatering Technology
Location: Duncan, British Columbia, Canada
This Canadian salmon hatchery needed to remove waste (fish feces and unconverted feed) from a re-circulation settling lagoon [photo 1].
Geotube® dewatering technology was selected for this lagoon cleanup. The process involved a polymer tank and dosing pump that fed to an unfiltered water sump pump and mixing manifold to deliver wastes from the fish production facility to the Geotube® containers. Once the filtered effluent drained from the Geotube® containers, the liquid can be deposited to an effluent pond or returned to the facility [photo 2].
This lagoon cleanup project was successful for the hatchery.
And this cleanup process was approved as a "Best Management Process" for Aquaculture by the State of North Carolina.
