A high-resolution technique to size suspended solids in flow-through fish farms

The practical effectiveness of the technique was tested by predicting the efficiency of drum filtration for the effluents from two commercial trout farms. The maximum difference between predicted solid removal according to laser data and solid removal determined by a standard method was 3.8 basis points. Important applications are the identification of particle-destroying units or processes within fish farm facilities, and the optimisation of filter pore sizes and hydraulic residence times for microscreens and sedimentation units respectively.
