APPLICATION OF THE LIMITING-CONSISTENCY WEB COMPRESSION MODEL TO VACUUM ASSISTED DRAINAGE CELL TESTS

The limiting-consistency web compression model was applied to the resu lts of drainage cell experiments. The concept of limiting consistency ir simple: any dewatering system at constant pressure eventually reach es a limiting consistency (solids content). The web compression model was found to describe the basic form of dewatering behavior very well. However, the effect of surface tension on dewatering rate and limitin g consistency points out the shortcomings of applying traditional visc ous flow models to the dewatering of wood pulp.
