The accurate determination of the coal slime filter cake pore structure has always been a problem in field solid–liquid separation. An innovative measurement method for after filtration dehydration water, including preparation cake, solidification and test was established this paper. Epoxy resin curing agent can ensure strength red colorant realize separation particles pores. most suitable perf...

Drilling fluid is the most important lifeline of the drilling operation, that main task is facilitate the cuttings removal of the drilling. There are varieties of drilling fluids such as sodium bentonite based-drilling fluid is called “mud” and drilling foam or surfactant based-drilling fluid is called “soap”. The present work aims are study on the modified drilling mud properties by using the ...

The filtration properties in solid–liquid separation mainly depend upon the filter cake properties, for instance, resistance. However, particle size distribution, shape, and their arrangements significantly impact filtration. This paper aims to review work done so far collate both fundamental applied with regard quantification of properties. resistance porosity terms as well varying distributio...

This paper deals with the results from experiments concerning the effects of an increasing shear rate at the edge of the membrane on reducing concentration polarization and on controlling membrane fouling during filtration of river water. Concentration polarization of humic substances in NF and MF membranes can be reduced by increasing the shear rate. The concentration polarization model can pr...

The paper considers an axisymmetric problem of filtering suspensions with the formation a cake on filter surface. It is supposed that has elastic–plastic properties. Using mass conservation equation and Darcy’s law, suspension filtration equations at regime are derived, which characterize partial irreversibility characteristics when system unloaded after loading. An also derived describes incre...

Specific parameters of cake filtration, such as the filter and medium resistances, can be determined using pressurized housing cell standardized in guideline VDI 2762 by measuring filtrate mass on a laboratory scale. For reproducible measurements an exact detection filtration start, improved test setup is presented compared with standard according to 2762. On basis without particle system filte...
