Reverse osmosis unit: URS and qualification document flow

The User Requirement Specification is the first document in the qualification set, and the one every later verification traces back to. Pharma4i generates the URS today. The rest of this flow is shown so the scope is clear; those documents are marked Soon and are not produced by the product.

Qualification document flow for a reverse osmosis unit.

Your URS is the input to every document to its right. Each requirement carries an ID so verification can be traced back to it.

What is specific to a reverse osmosis unit

Design Qualification DQ

Carries CSV-specific content per GAMP 5: the design is reviewed against the software category, the supplier assessment outcome and the data integrity requirements.

Operational Qualification OQ

Carries CSV-specific content per GAMP 5: configured functions, security and access control, audit trail, electronic records and electronic signatures.

PQ Phase 1 — intensive sampling PQ-1

Daily sampling of all points, including each point of use, to establish the system can consistently produce water of the specified quality.

PQ Phase 2 — sanitisation regime PQ-2

Sampling continues at the same frequency while the proposed operating and sanitisation procedures are followed; water may be used in manufacturing at the site's risk once Phase 1 is satisfactory.

PQ Phase 3 — one year, seasonal variation PQ-3

Runs for twelve months so that seasonal changes in feedwater temperature and quality are captured. This is the most commonly underestimated qualification in the industry: the system is not fully qualified until Phase 3 is complete.

Cleaning Validation CV

Acceptance limits derive from the permitted daily exposure (PDE) for the product, not from arbitrary dose or 10 ppm rules; sampling covers worst-case surfaces and hold times.
