Objectives
1) To use LIF to visualize the CP layer near the membrane in the crossflow environment and to characterize the CP dynamics under different hydrodynamic conditions; 2) To use LDA to detect the shear flow and micro-turbulence in the boundary layer over the membrane surface and to study their impact on the material transport and CP formation; 3) To validate and modify the CP models based on the laboratory findings and to develop effective CP control strategies.
