The Half Area Filter Press, or Mini-press (140-60), consists of a modified low pressure regulator with a CO 2 bulb pressurizing assembly and a filtration cell body. A rubber diaphragm boot contains the fluid and separates it from the pressurizing gas. This enables the unit to be operated while inverted, which negates the effect of particles settling on the filter medium prior to pressurization ...

Determining Hydraulic Conductivity of Soil-bentonite Using the Api ...

Using seepage consolidation theory to interpret the filter press tests produces hydraulic conductivity consistent with that obtained from the other tests. The filter press test results are used to illustrate a method for estimating the hydraulic conductivity of soil-bentonite in a cutoff wall by taking backfill consolidation pressures into account.

Bentonite - Wikipedia

Creating a bentonite slurry for fining after wine pressing The main uses of bentonite are in drilling mud and as a binder, purifier, absorbent, and carrier for fertilizers or pesticides. As of around 1990, almost half of the US production of bentonite was used as drilling mud. Minor uses include filler, sealant, and catalyst in petroleum refining.
