Processing Plant Waste Dewatering
Bishop Aquatic Technologies has
used the Geotube®
solution for the
dewatering of fish processing waste (including blood, fish
parts, lipids), and develop dewatering process with Geotube®
containers.
Dewatering fish processing
waste was one of the largest tests the Geotube®
solution
had faced, and it passed with flying colors.
By first allowing the solids
drop out over a gravity flow separator, liquid waste is then
directed into a homogenization tank. The pH is rigorously
tested when required. Polymer is injected into feed line,
then passes through a mixing chamber en route to the Geotube®
container.
The Geotube®
solution can replace Fused
Air Floatation (DAF) systems. DAF systems have a high
capital and operating cost. The Geotube® dewatering system
allows for efficient treatment and retains compostable
nutrients.
The results of the dewatered
effluent are impressive:
Solids removal: 97%
BOD reduction: 80%
Nitrogen capture: 92%
Oils and fats removal: 97%.
