Factory planning for water bottling projects
Decision guide | design and commissioning
Use a UV unit within a validated operating envelope that includes the actual water transmittance and maximum flow. Instrument indication, lamp condition and fouling control must support a clear permissive or diversion decision rather than merely showing that the lamp is on. Required performance and validation conventions depend on the hazard analysis and applicable requirements. This page does not prescribe one dose or claim UV alone protects downstream tanks, piping, bottles and caps.
01
Use a UV unit within a validated operating envelope that includes the actual water transmittance and maximum flow. Instrument indication, lamp condition and fouling control must support a clear permissive or diversion decision rather than merely showing that the lamp is on. Begin with microbial treatment objective: document microbial treatment objective from current site evidence; name the owner, source and review date. Use uv transmittance range next. Test normal and credible adverse uv transmittance range conditions; state the exception and stop rule. Close the maximum validated flow stage through maximum validated flow evidence, specifically a maximum validated flow interface map with closed gaps or named owners and due dates.
Document microbial treatment objective from current site evidence; name the owner, source and review date. Microbial treatment objective risk: weak microbial treatment objective evidence leaves ownership and the decision basis unclear. Retain a dated microbial treatment objective basis with source, owner, status and approval.
Test normal and credible adverse uv transmittance range conditions; state the exception and stop rule. UV transmittance range risk: incompatible uv transmittance range can block startup or permit an unsafe release. Retain a uv transmittance range test showing conditions, raw result, exception and disposition.
Trace maximum validated flow across physical and responsibility interfaces; close or assign every dependency. Maximum validated flow risk: unmapped maximum validated flow leaves an interface outside effective control. Retain a maximum validated flow interface map with closed gaps or named owners and due dates.
02
At reactor validation basis, control the approved reactor validation basis basis and reopen it after a relevant process, material or site change. Set intensity sensor beside reactor validation basis; observe intensity sensor at the decision point with a named method and verified instrument status. Lamp age and output decides the case. Untested lamp age and output can fail when routine conditions vary. The reactor validation basis table entry pairs its action with the controlled reactor validation basis revision and its requalification trigger; the risk for intensity sensor is that poorly located intensity sensor can hide deterioration until product is affected.
Control the approved reactor validation basis basis and reopen it after a relevant process, material or site change. For Reactor validation basis, compare the result against the controlled reactor validation basis revision and its requalification trigger; reject the option if outdated reactor validation basis separates the approved basis from the installed condition.
Observe intensity sensor at the decision point with a named method and verified instrument status. For Intensity sensor, compare the result against the intensity sensor location rationale, method and instrument status; reject the option if poorly located intensity sensor can hide deterioration until product is affected.
Challenge lamp age and output at startup and stable production, then reconcile any difference. For Lamp age and output, compare the result against startup and stable lamp age and output results with approved exceptions; reject the option if untested lamp age and output can fail when routine conditions vary.

Control starts with sleeve fouling, passes through cleaning method, then tests flow permissive. A failure of sleeve fouling matters because unclear sleeve fouling ownership delays containment, investigation and restart. For cleaning method, retain a signed cleaning method comparison using common assumptions and stated exclusions. At flow permissive, contain the flow permissive event before unrepresentative flow permissive can pass a convenient trial and fail in routine use.
Assign sleeve fouling to a named role with an escalation path and dated closure. Sleeve fouling risk: Unclear sleeve fouling ownership delays containment, investigation and restart. Detection and containment use the sleeve fouling owner, escalation route and closure entry.
Compare cleaning method options on the same assumptions and state every exclusion. Cleaning method risk: Non-comparable cleaning method options can make weaker evidence appear acceptable. Detection and containment use a signed cleaning method comparison using common assumptions and stated exclusions.
Verify flow permissive with representative inputs, operators and credible operating variation. Flow permissive risk: Unrepresentative flow permissive can pass a convenient trial and fail in routine use. Detection and containment use the flow permissive protocol, actual conditions, raw results and approval.

Required performance and validation conventions depend on the hazard analysis and applicable requirements. This page does not prescribe one dose or claim UV alone protects downstream tanks, piping, bottles and caps. Authorize low-intensity action from the low-intensity action trend, investigation trigger and dated review decision. Revisit startup diversion whenever disconnected startup diversion can expose product, people or continuity. Keep routine challenge and records open; the routine challenge and records project must approve routine challenge and records only when gaps are closed or retained as named, dated actions. Close routine challenge and records with the accepted routine challenge and records record with residual actions, owners and due dates.
Trend low-intensity action, define the investigation trigger and record the review decision. Acceptance relies on the low-intensity action trend, investigation trigger and dated review decision. Without low-intensity action trends, drift can outrun investigation. Reopen Low-intensity action when that condition occurs.
Connect loss of startup diversion to product hold, safe state and continuity response. Acceptance relies on a cause-and-effect test linking startup diversion loss to the intended response. Disconnected startup diversion can expose product, people or continuity. Reopen Startup diversion when that condition occurs.
Approve routine challenge and records only when gaps are closed or retained as named, dated actions. Acceptance relies on the accepted routine challenge and records record with residual actions, owners and due dates. Open routine challenge and records gaps can be mistaken for final acceptance. Reopen Routine challenge and records when that condition occurs.

Buyer questions
Document microbial treatment objective from current site evidence; name the owner, source and review date. Keep the point open until its evidence owner and review date are named.
The controlled reactor validation basis revision and its requalification trigger. A file name alone does not prove the actual conditions, result or disposition.
Non-comparable cleaning method options can make weaker evidence appear acceptable. Contain affected product or people, trace the effects and authorize restart against the approved rule.
Assign it to a named role. Seek specialist, supplier or authority confirmation where the evidence crosses the project team’s competence boundary.
