Establishment and Mechanism Investigation of Partial Blocking Filtration Model of Microfiltration

Membrane filtration mechanism is one of major study projects for membrane filtration process.In order to depict the mathematic model for microfiltration(MF) velocity variation,the partial blocking filtration model for MF membrane was established by supposing web passage of membranes and correlating Kozeny-Carman equation with Darcy law.The variation rule of MF velocity was derived using porosity and hydraulic radius as key factors.The established model was proved by dead-end filtration test using cellulose ...
