The non-filtrate is filtered in the non-filtrate chamber (6a) through the filter element (8) and is drawn as a filtrate with a filtrate pressure (P2).
The resulting filtrate flows out into a filtrate discharge channel (600) through the discharge port (303).
According to the invention, the filtrate channel (1) has at least one barrier (7) which is located at a distance from the filtrate outlet (6), which is impermeable to the filtrate liquid and which therefore stops the flow of filtrate.
Additionally, transferring the filtrate to a filtrate collection vessel and determining a volume of filtrate in the filtrate collection vessel.
A vacuum is applied on the filtrate side in the clear filtrate filtration region (KF) for the purpose of promoting filtrate passage.
In this configuration, a permeate collector at an upper potting head may be connected to the permeate conduit by a second permeate conduit.
The sieving chambers have a common filtrate chamber located in between them and discharged by a filtrate discharge pipe (10) provided with a valve (11).
The filtrate is drained via these channels to openings (4), which permit passage to the filtrate side of the barrier.
The filtrate network (16) includes a number of longitudinal filtrate chambers (18) and one or more filtrate channels (20) which transect the chambers (18).
The filter unit (F) has a first filtrate outlet (6) and is in communication with the filtrate compartment (35).
The filtrate is discharged from the filtrate collection reservoir, and the filter transfer mechanism removes the filter.
The structure contains a filtrate conduit network comprised of both an intersegment filtrate conduit, formed by the arrangement of the segments, and at least one intrasegment filtrate conduit (14) within at least one segment.
The present invention determines the percentage of filtrate contamination in a sample comprised of a mixture of crude oil and an oil based mud filtrate or of formation brine and a water based mud filtrate.
A cup-like filtrate reservoir (6) is integrally connected to the water reservoir, forming a filtrate passage (22) between the water reservoir and filtrate reservoir.
The filtrate channel (20) communicates with at least one filtrate duct (32) that discharges filtrate from one or both end faces (14, 16) of the monolith (11).
