electro-osmosis

a type of OSMOSIS in which the SEMIPERMEABLE MEMBRANE has a potential difference across it so that charged solvents move from the negative to the positive side.

Once this point has been reached for a pipe coating under CP, the electro-osmosis becomes dominant in forcing more water into the coating, ultimately to form blisters.
Electro-osmosis depends on the net amount of ion migration towards an electrode location, and especially in low permeability, clayey soils, the net ion migration may be high and it can significantly affect the decontamination process (Acar and Alshawabkeh 1993; Lageman 1993).
