Abstract

An electrochemical treatment system includes a treatment fluid supply manifold, a fluid return manifold, and an electrode section connected to the treatment fluid supply manifold. A plurality of treatment fluid supply ports feed fluid through or across the electrode and a plurality of fluid return ports proximate the treatment fluid supply ports are connected to the fluid return manifold. A porous pad is coupled to the electrode section for contacting a substrate to be treated and receives the treatment fluid via the plurality of treatment fluid supply ports. The plurality of fluid return ports remove spent and excess treatment fluid and gases from the substrate, the surrounding air, and the porous pad.
