Abstract

An improved apparatus and process for spray-rinsing chemically treated articles or workpieces with a multi-spray counterflow rinse system wherein the rinsing of chemically treated or otherwise processed workpieces are either supported or suspended by a support carrier which is defined by an article support rack or by a perforated process barrel in which the articles or workpieces are supported therein, and wherein the rack and the barrel include an internal spray assembly that is removably coupled to the rinse tank spray assembly when either the rack or barrel are positioned within the rinse tank, and whereby a fresh uncontaminated rinse solution, preferably fresh water, is pressurized when entering the rinse tank spray assembly. The pressurized fresh water also defines a means to purge the rinse tank spray assembly after completion of each rinse cycle.
