Product Description
1. INSTRODUTION
This is a filter press with differential pressure of 0.69MPa. It can be used to measure the filter loss of drilling fluids and prepare the mud cake formed after filtration. The instrument has been widely applied in the oil fields, geological exploration department and laboratory for analysis and measurements of drilling fluids.
Filtration and wall-building properties of drilling fluids and cement slurries are determined by a filter press. The filtration rate is a measure of fluid loss measured in milliliters [1 milliliter (ml) = 1 cubic centimeter (cm3)] under 100 pounds per square inch (psi) (690 kPa) of pressure through a special filter paper for 30 minutes. Wall-building characteristics are demonstrated by the thickness and consistency of the filter cake (the residue) deposited on the filter paper at the end of this period. The filter cake is measured to the closest 1/32" (0.8 mm). The low pressure filter press assemblies described in this booklet consists of a filter cell mounted in a frame, a pressure source, a filtering medium, and a graduated cylinder for receiving and measuring the filtrate.
The filter cell, or drilling fluid cell, is constructed of rustproof anodized aluminum and chrome plated brass, or stainless steel.
Pressure sources deliver the required 100 ± 5 psi (690 ± 35 kPa) and may consist of compressed nitrogen or air in cylinders, CO2 gas cartridges, high pressure air or water systems, or a dead-weight hydraulic pressure assembly.
DUE TO THE HAZARD OF EXPLOSION, COMPRESSED OXYGEN SHOULD NOT BE USED AS A PRESSURE SOURCE.
The filtering medium normally is a filter paper that has been especially hardened for filtrate testing. The filtrate receiver is a 10 or 25 ml graduated cylinder.

2. STANDARD FILTER PRESS TEST PROCEDURES
Follow the steps in this procedure to operate the filter press with a compressed gas or dead-weight hydraulic pressure source:
1. Assemble the clean, dry parts of the filter cell in the following order :
• base cap
• rubber gasket
• screen
• a sheet of filter paper
• rubber gasket
• filter cell
2. Secure the cell to the base cap by rotating it clockwise.
3. Fill the cell with the test sample to within approximately 1/4" (6mm) of the top.
(Filling the cell to this level lessens the volume of pressurizing gas required from the pressure source.)
4. Set the filter press cell assembly in place within the frame.
5. Check the top cap to make sure the rubber gasket is in place. Place the top cap, already connected to the pressure source, onto the filter cell and secure the cell in place with the T-screw.
6. Place a dry graduated cylinder under the filtrate tube, either on the support or in the clip.
7. Depending upon the pressure source being used, apply pressure to the cell following the appropriate pressure source procedure as outlined in Section 3.
8. At the end of 30 minutes (or 7-1/2 minutes - Refer to Note below), close the pressure source valve and back off the regulator, open the safety-bleeder valve. This releases the pressure on the entire system.
9. Measure the volume of filtrate collected in the graduated cylinder and record the filtrate loss in milliliters as the API (30 minute) filtrate loss of the drilling fluid, or milliliters x 2 for the 7-1/2 minute test.
10. Loosen the T-screw, remove the cell top, and then remove the cell from the frame.
11. Discard the drilling fluid.
12. Disassemble the filter cell and carefully remove the filter cake and filter paper from the base cap.
13. With a gentle steam of water (or, in the case of oil drilling fluids, with clean
base oil), carefully wash excess drilling fluid from the cake.
14. Measure and record the thickness of the filter cake to the nearest 1/32" (0.8 mm).
15. If desired, record properties of the filter cake such as texture, hardness, flexibility, etc.
