Ion Exchange Equipment


This Code defines the procedures for the accurate testing of ion exchange equipment for the purpose of determining level of performance. This test Code applies to ion exchange equipment and systems that are utilized for: (a) The conditioning of makeup, feedwater and/or steam condensate in a conventional fossil fuel cycle. (b) The conditioning of makeup, feedwater and/or steam condensate in a nuclear cycle, primary coolant purification, core-bypass purification and use in waste management systems. (c) The conditioning of process waters. Ion exchange systems will typically consist of all equipment, including service, regeneration and resin storage vessels; and includes all piping, pumps, valves, controls, instrumentation and ion exchange resins. This Code applies to the performance of ion exchange equipment at design, minimum or maximum flow rates, depending on the purpose of the test, with regard to one or more of the following: (a) Water quality, influent and effluent (b) pressure drop, flow and temperature (c) Operating ion exchange capacity (d) Regeneration efficiency (e) resin volume and testing (f) Backwash and rinse properties (g) Regenerant purity and solution concentrations (h) Resin transfer equipment.
