| Abstract: | A new device designed for sieving of fish farm effluent (trademark Triangel Filter TF 2400) was tested in order to prove if such an apparatus may be used instead of the swirl concentrator. The phosphorus reduction was estimated by water sampling and phosphorus budget and by measuring the phosphorus content in flushing water and in settled sludge. Sieving is a promising and useful method to treat aquaculture effluent, especially in ‘high-tech’ systems (recirculation, warmed water facilities) where high effluent quality and the most effective removal of solids is needed. |
