Abstract
A regenerative base ion exchange process involving the step of passing a liquid upwardly through a bed of particulate solid base ion exchange resin in a chamber of a two-phase reactor to regenerate said resin, wherein the rate of liquid flow is such that the solid resin is compacted and held by the liquid as a compact bed against a barrier located above it and is prevented by the liquid from sinking.
