ASME PTC 31 – High-Purity Water Treatment Systems
Only the relevant portion of this Code need apply to any individual case or test under consideration. In some cases the procedure is simple; however, for complex systems or complex modes of system operation, the procedures and calculations of test results require more involved provisions for testing.
This Code is applicable to the following types of highpurity water treatment systems, which are either used individually or in various combinations depending on requirements of the process:
(a) membrane equipment including but not limited to, microfiltration, ultrafiltration, nanofiltration, and reverse osmosis
(b) ion exchange equipment including, but not limited to, softeners, dealkalizers, multibed demineralizers, mixed-bed demineralizers, and condensate polishers
(c) hybrid equipment including, but not limited to, electrode ionization (EDI) and electrodialysis reversal (EDR).
This Code applies to equipment and systems that are utilized for
(a) the conditioning of makeup, feedwater, and condensate for steam generation
(b) the conditioning of process waters
This Code applies to the performance of high-purity water treatment systems at design, minimum flow rates or maximum flow rates, depending on the purpose of the test, with regard to one or more of the following:
(a) water quality and quantity of influent and effluent
(b) pressure drop, flow, and temperature
(c) startup, shutdown, and lay-up procedure
(d) operating efficiency
(e) media testing
(f) media cleaning and maintenance
(g) chemical purity and solution concentrations
(h) associated chemical equipment
