(57) An electrolysis process is disclosed in which an electrolyte, either anolyte or catholyte,
is transferred serially from one cell, in a bank of a plurality of cells, to the corresponding
electrolyte compartment of a succeeding cell in the bank. The transfer is accomplished
by means of a gas-lift in which gas, present in the compartment of the electrolyte
to be transferred, rises through a confined space. The space is dimensioned such that
the gas serves to lift the electrolyte upward to a point where the gas and liquid
separate and the liquid electrolyte is allowed to fall freely to a collection point
from which it is introduced into the corresponding electrolyte compartment of a succeeding
cell.
