filter cake

At the end of filtration, the solid filter cake can be removed.

Such particles can physically plug the pores in the filter cake.

The wet solids left in the filter are called the filter cake.

With increasing layer thickness the flow resistance of the filter cake increases.

The filtered slip is then pumped into presses to remove the water and leaving filter cakes.

This is analogous to the washing of filter cake to remove soluble components.

A filter cake is formed by the substances that are retained on a filter.

Mud is designed to deposit thin, low permeability filter cake to limit the invasion.

They increase the viscosity of the aqueous phase and decrease the filter cake permeability.

A good quality filter cake containing bentonite is known to limit bore hole enlargement.

The filter cake is shipped to third-party custom refiners for final refining before being sold.

A higher overall liquid removal rate is achieved by the prevention of filter cake formation

Figure 2 represents xanthan filter cake.

This creates a shear stress that cracks the filter cake and lower the formation of fouling.

The filter cake grows in the course of filtration, becomes "thicker" as particulate matter is being retained.

After a certain time of use the filter cake has to be removed from the filter, e.g. by backflushing.

Mud should have thin, slick filter cake, wellbore with no cuttings, cavings or bridges.

The specifications of the filter cake dictate the filtration method of choice

Granulating mill - filter cake or amorphous and paste-like products respectively

Over time, a thin layer of filter cake (called muck) accumulates on the lint filter.

Problems occur if a thick filter cake is formed; tight hole conditions, poor log quality, stuck pipe, lost circulation and formation damage.

A filter press uses increased pump pressure to maximize the rate of filtration and produce a final filter cake with a water content under 65%.

During this process the not passing particles or molecules are forming on the membrane a more or less a pulpy mass (filter cake).

The filter cake was dropped to a drumming station, and the filtrate was pumped to one of two new agitated precipitation tanks.

The filter cake was dropped to a holoflite conveyor where it dried to UF*3/4HO and conveyed to a mobile hopper.
