Anode in filters 1

[DaniMP]

Hi everybody !

A quick question :
My supplier of salted water filters has put the galvanic anodes in the top part of the filters. The entrance of the filters is by the side approximatively at 4/5 of the height of the filters, so the anodes won't be in the water, except during the washing (the flow is then countercurrent).

I believe the anode have to be into the liquid to be useful, will this design work ?

Thanks !
Daniel

Hi Daniel,

I think the anode should be placed in a position where it is always covered with water.
In order for cathodic protection to work anode and cathode have to be in the same electrolyte, so when the anodes are in the air no current will flow and CP won't work.

Kind Regards

yes, for the anode to work it has to be in the electrolyte (water), anode in air won't complete the circuit until in contact with water

Thank you everybody !!!

Maybe you just installed the filters upside-down.

Mcgyver makes a good point. If filters are installed properly there should be no air in the filter. Filters are designed to filter water and should be completely flooded during normal operation.
