Abstract: |
Empirical and theoretical models have been developed to evaluate the efficiency of a filamentous mat for the removal of turbidity. The removal mechanisms applied in the treatment were interception, diffusion, sedimentation and inertia impaction. The empirical models for the turbidity removal efficiency and mat design were established using excel solver, based on the experimental work, with dimensionless variables included. A model sensitivity analysis indicated that the particles size plays an important role in determining the removal efficiency and mat design. The theoretical model for the turbidity removal efficiency was developed according to the isolated single-sphere model. In general, both empirical and theoretical models were consistent with the experimentally measured data.
