Standard Test Method for Capacity of Mixed Bed Ion Exchange Cartridges

Importancia y uso:

5.1 This test method can be used to evaluate the performance of unused mixed bed ion exchange cartridges for conformance to specifications.

5.2 This test method provides for the calculation of capacity in terms of the volume of water treated to a conductivity end point.

5.3 The test method as written assumes that the ion exchange resins in the cartridge are either partially or fully converted to the H⁺ or OH^– form. Regeneration of the resins is not part of this method.

5.4 This test method provides for the calculation of capacity on a cartridge basis.

5.5 This test method may be used to test different size mixed bed resin cartridges. The flow rate of test water and the frequency of sampling are varied to compensate for the approximate volume of resin in the test cartridge.
