The main function of a clay filter is to remove unwanted surface active
surfactants, colouring and other additives which may be present from the
refining process or during transportation of Jet Fuel.
These unwanted surfactants can accumulate in the coalescer elements
of a filter/water separator and reduce their water removal efficiency.
Therefore such clay filter vessels are normally installed in front of a
filter/water separator vessel.
To enable optimum performance of the adsorbtion process of the Attapul
-
gas Clay, the recommended flow rate per element is 25 l/min.
