Abstract:
In a method of hydrostatic pressure-testing a transportable-sized water treatment module by flowing a test fluid into, through, and out of said module, optionally followed by passing a flushing liquid into, through, and out of said module to flush remaining test fluid from the module, and of preparing the hydrostatic pressure-tested module for storage and/or shipping, the improvement comprising the steps of:(a) introducing a biocidal agent into at least a portion of the test fluid being fed to the module to hydrostatic pressure-test the module or into at least a portion of the flushing liquid being fed to the module to flush test fluid from the module to prepare a hydrostatic pressure-tested and biocidally-treated module; (b) displacing at least a portion of the liquid containing said biocidal agent from the hydrostatic pressure-tested and biocidally-treated module by using a gas which has been passed through sterilizing filters; and, (c) thereafter sealing the hydrostatic pressure-tested and biocidally-treated module against biological ingress so as to maintain an aseptic condition during storage and/or shipping.
