Rex and Bruce et al.,

Electroflotation is a separation process in aqueous process streams in which
electrolytic gas generation (hydrogen and oxygen mainly) is used to float
away flotable materials (anything that will stick to or associate with a
bubble). Basically, the process stream is passed through a column of gas
bubbles rising from a set of electrodes or passed directly between the
electrodes. Direct current flowing through the electrodes split water into
hydrogen and oxygen. The bubbles carry particulates and surface active
components to the surface of the water stream where they can be removed
(either by overflow or active skimming). In addition to this physical
separation process there is also the possibility under certain conditions
for the electrochemical destruction of stream components as well as
disinfection.

My research interest is in application of this technology to promote food
safety. See, for example:
