Benthic Table Waste Cleanup
Product: Geotube® Dewatering Technology
Location: Salmon Farm
A local salmon farm wanted to create a system to clean up benthic deposits from their ocean environment.
Geotube® dewatering technology played a key role in this cleanup project. The following process was used for the cleanup.
First, a pump was used to extract the benthic deposits and load the material to a tank on a nearby boat.
Once the tank was filled, the boat approached the shore where it pumped the waste into a Geotube® unit.
The conditioning and flocculation was achieved in the line between the boat and the dewatering unit.
The benthic deposit materials were treated in two dewatering tests: with and without the use of flocculants. The results were very definitive.
Without Flocculants -- Result was unsatisfactory and the dewatering time was too slow [photo 1].
With Flocculants -- Result was highly satisfactory in terms of water clarity and nutrients removal [photo 2]. This method's dewatering time was very fast.
