Water used for pharmaceutical preparations is prepared by distillation. This provides the highest degree of purity and assurance, but for large water consuming, less sensitive processes like device and container cleaning, this is not economically feasible.

It is also highly desirable to avoid the use of industrial chemicals in these operating environments, so water purifying processes have tended to favour technologies driven by electricity.

e-RPM have devised a water facility purification strategy that achieves this. Initial water supply purification may be addressed by reverse osmosis desalination, followed by electro-deionisation where very high purity is specified.

Water sterility is achieved and maintained using ultraviolet sterilisation and micro filtration. Removal of trace organic oxidisable materials can be undertaken by UV/ozone advanced oxidation techniques again avoiding chemicals.

System quality and output data can be easily accessed with remote process monitoring and management services which allow the facilities to be unmanned, and any non-conformance alert directed to the facility management team using SMS text messaging and e-mail.
