Cage Waste
Removal Text:
The Geotube®
container
can be used with a special mortality retrieval system called
a Lift Up system, to gather unconverted feed, as well as
fish feces. A pump is used, via remote control to extract
the waste. The cage waste is then pumped from the Lift Up
collection system to a floating containment tank. Once the
containment tank is filled and returns to shore, the
collected waste is then pumped into the Geotube®
container.
As the cage waste is pumped to the Geotube®
container
it is conditioned with a polymer in order to separate the
liquid and the solids. The effluent filtering through the
Geotube®
container
is released back to the ocean and valuable nutrients are
retained in the Geotube®
container.
The Geotube®
solution
has proven to be effective in terms of water quality and
nutrients removal when used for cage waste removal:
Solids removed
95%
90+ %
Phosphorous
70+ % Nitrogen
Geotube®
dewatering technology produces a clean, clear effluent water to be
returned back to the ocean environment. |
