Screening of Microfiltration and Ultrafiltration Ceramic Membranes for Produced Water Treatment and Testing of Different Cleaning Methods
… operations conducted. It was found that the cake layer formation and at a lesser degree the intermediate blocking were the predominant fouling mechanisms which controlled the permeate flux of filtrations at all operating conditions tested.

Modeling and interpreting the observed effects of ash on diesel particulate filter performance and regeneration
… across the substrate wall with soot and ash cake layer formation. DPF models are also used to investigate the process of ash transport and catalyst deactivation with increasing ash load level. DPF ash aging is found to have negative effect on passive regeneration due to the catalyst …

Mechanism study of virus removal in membrane filtration and the application to improve virus removal
… permeate flux decrease with the pore blockage-cake filtration model, it was determined that HAdV-2 fouled the membrane and decreased the effective membrane pore size, leading to the enhanced virus removal and the decreased permeate flux. It was also found that, the aim of high virus removal …
