Hydrodynamic analysis of particle collection efficiency: comparing downflow and upflow filtration
(UNIV ESTADUAL MARINGA, PRO-REITORIA PESQUISA POS-GRADUACAOMARINGA, 2012)
Models of the filtration phenomenon describe the mass balance in bed filtration in terms of particle removal mechanisms, and allow for the determination of global particle removal efficiencies. These models are defined in ...
