Teaching suggested applications*

-          Study of a porous medium (sand)

-          Pressure measurement in the column during the filtration

-          Study and visualization of the filter clogging

-          Study of the regeneration of the sand

Description

The GPBFS1 bench allows the filtration study on sand.

In a first stage, we supply the column with polluted water with the aid of a pump. The sand will retain the impurities contained in the water.

In a second step, we will supply the column from below with the system water to clean the sand of the column.

The robust design of this equipment makes it perfectly suited for school use.

Its anodized aluminum structure on wheels makes it very robust as well as a great flexibility of integration into your premises.

The manufacture of this equipment meets European machine directive.
