Dissolved micro-bubble flotation for water purification in recirculating aquaculture system


Dissolved micro-bubble flotation for water purification in recirculating aquaculture system



Fisheries Science Dalian 27(4): 167-170



A dissolved micro-bubble flotation system was established and studied for the purification of fine solids in a recirculating aquaculture system. The liquid height, liquid flow rate and air dissolved pressure were evaluated in single-parameter and orthogonal experiments. Results showed that turbidity removal was highest when liquid height was kept at 0.8 m, while pH increased at a liquid height of 1.0 m.
