Effect of biofouling on the exclusion efficiency of 2mm wedge-wire screens

摘要: The effect of biofouling on entrainment properties wedge-wire screens was tested using a model intake facility with two side-by-side ports. Two 2mm slot-width were deployed; one permitted to foul, the other not. Entrainment rates ichthyoplankton species, naked gobies (Gobiosoma bosci) and bay anchovies (Anchoa mitchilli), measured through both weekly for month. response species similar. As fouling became more severe, fouled screen remained relatively constant compared clean screen. authors suggest that effectively reduced slot size screen, causing greater physical exclusion smaller, gobies.
