Rotationally symmetric fluid distribution cell modules combinable to form stacks for the processing of solutions are disclosed. Each module comprises at least one membrane and/or diaphragm and/or electrode and a plate, the latter having a central aperture and a plurality of fluid distribution ports symmetrically spaced in a configuration about the aperture. Connecting fluid passages lead from at least one of the ports in the plate to the central aperture such that part or all of the fluid introduced into one of those ports will flow into the aperture. In some applications of the modules there will be a second connecting fluid passage leading from the aperture to a second port such that at least part of the fluid introduced into the aperture will flow out the second port. Stacking the plates in combination with different types of electrodes, membranes and/or diaphragms provides a cell stack in which a large variety of fluid treatment processes may be carried out. Fluid distribution to and in the stack and among the plates is controlled by the angular orientation of the plates in the stack with respect to each other, with respect to fluid input and output streams, and with respect to internal process streams within the stack.
