Beverage Deaeration & Dissolved Oxygen
Specify where oxygen must be controlled, where it can enter again and how the finished package will be assessed before choosing a deaeration module.

Direct answer
Define oxygen performance at named process points.
Beverage deaeration reduces dissolved gases in a defined stream, such as process water or product. A water-deaerator outlet reading describes only that sampling point; it does not prove oxygen performance at the filler or in the sealed bottle or can. Build the requirement around the recipe, incoming water, temperature, flow range, downstream tanks and transfer route. Agree dissolved oxygen measurements at named locations and use total package oxygen measurements when headspace oxygen is relevant. Ask the process and packaging specialists to set product-specific limits and the test conditions attached to any equipment guarantee.
Project definition
Start with the complete decision basis.
Specify where oxygen must be controlled, where it can enter again and how the finished package will be assessed before choosing a deaeration module.
Product basis
Beverage family, oxygen sensitivity, recipe changes and the quality attributes the buyer needs to protect.
Feed conditions
Water analysis, inlet dissolved oxygen, temperature, flow range, pressure and seasonal variability.
Plant interface
Available stripping gas where used, gas specification, supply stability, buffer tanks, transfer pumps and CIP boundary.
Measurement boundary
Sample locations, instruments, calibration, sample handling, units and finished-package test responsibility.
System or development path
Build a review sequence with named records and decision owners.
Map the oxygen boundary
Draw the water or product route from feed through treatment, holding, blending, filling and closing.
Define operating cases
Include startup, minimum and maximum flow, pauses and planned recipe changes in the supplier discussion.
Plan representative sampling
Use agreed procedures that limit oxygen pickup during sampling and record instrument conditions.
Compare stage results
Separate deaerator performance, downstream pickup and finished-package results before assigning corrective actions.
Quotation comparison
Agree the comparison basis before sampling or ordering.
| Decision area | Buyer should provide | Proposal should clarify |
|---|---|---|
| Module selection | Feed and required outlet conditions. | Technology, design envelope and guarantee location. |
| Gas and utilities | Local gas quality, pressure and available services. | Consumption basis, alarms and buyer-supplied connections. |
| Downstream protection | Tanks, transfer route and operating interruptions. | Pickup risks and controls outside the module boundary. |
| Acceptance | Named sample points and approved instruments. | Dissolved oxygen and package measurements with conditions. |
Buyer working matrix
Define oxygen performance at named process points.
A staged sample plan helps identify where a change occurred; it does not establish universal acceptance limits.
| Point | Record | Question answered |
|---|---|---|
| Incoming water | Temperature, flow and oxygen result | What load reaches treatment? |
| Module outlet | Result under stated operating conditions | Does the module meet its defined boundary? |
| Filler inlet | Comparable measurement and transfer history | Has pickup occurred downstream? |
| Sealed package | Approved package test and elapsed time | What does the finished package contain? |

Decision evidence
Keep project evidence connected to each approval and release decision.
Evidence should be identified before the order or approval stage so both sides know what will support the next decision.
Approved engineering basis
Keep the signed specification, equipment list, package files, layout and interface responsibilities under revision control.
Manufacturing progress record
Identify agreed drawings, component confirmations, photographs, open questions and approval decisions by date.
Test and acceptance record
State configuration, materials, operating conditions, measurements, results, punch-list items and release status.
Delivery and handover package
Connect packing, serial numbers, manuals, backups, spare parts, training and support contacts to the delivered scope.
Do not turn one vendor rating into a product specification
A published module rating belongs to that equipment and its stated conditions. It should not be copied into a quotation as a universal beverage target. Request the supplier to explain the required feed quality, flow range, temperature and gas conditions, then define how deviations will be recorded during testing.
- Attach the rating conditions
- Label estimates and guarantees separately
- List inlet conditions outside the design envelope
Dissolved oxygen and total package oxygen answer different questions
Dissolved oxygen measures oxygen in the liquid. Total package oxygen also accounts for oxygen in the sealed package headspace. A low dissolved reading before filling can coexist with later oxygen pickup. Compare like-for-like methods and units, and avoid deriving package performance from a single upstream number.
- Name the physical measurement point
- Keep headspace and liquid results distinct
- Use a qualified sampling procedure
Include cleaning and restart behavior in the scope
The deaeration module needs an agreed operating relationship with blending, filling and cleaning. Ask how the line handles startup water, diverted streams, low flow and interruptions. Record who approves the transition from cleaning or standby into production and which measurements support that release. This creates a usable handover requirement without prescribing a generic process recipe.
- Identify diverted streams
- Record startup sampling decisions
- Assign cleaning and restart ownership
Decision gates
Move forward when the next commitment has enough written evidence.
Project stages overlap, but each commercial commitment should have a visible basis, named approvers and a list of unresolved items.
Engineering basis approved
The product, package, output, equipment boundary, layout, utilities, responsibilities and open assumptions are controlled.
Manufacturing and test basis approved
Drawings, component schedule, test materials, acceptance conditions, documents and planned evidence are agreed.
Delivery and handover released
Punch-list closure, packing, shipment files, site readiness, installation scope, training and support ownership are visible.
Before requesting a proposal
Build one brief that every resource can answer on the same basis.
This page is designed to help an international buyer prepare a clearer discussion, not to replace the responsible resource’s engineering or the buyer’s professional review.
Product
Beverage, process, hygiene, shelf-life and operating conditions.
Package
Container, closure, label, code, finished pack and approved files.
Output
Required rate for a named format, shifts, annual plan and changeovers.
Factory
Measured space, utilities, access, drainage and local site constraints.
Project scope
Equipment boundary, documents, FAT, delivery, startup and destination.
Allot Tech organized recurring buyer questions, project-scoping patterns, available catalog inputs and specialist-resource context into a decision sequence. No customer case, certification, output guarantee or factory ownership is implied unless separately verified for the named project.
Reference basis
Primary and specialist sources used to frame the buyer questions.
These sources support definitions and planning context. The current edition, local requirements and project-specific acceptance criteria still need confirmation by the responsible parties.
- Alfa Laval: Aldox Mini
A manufacturer example of water deaeration and its defined feed, gas, utility and measurement conditions.
- Anton Paar: Oxygen in beverages
Measurement context for dissolved oxygen, headspace oxygen and total package oxygen.
Manufacturing context
Use equipment views to ask more specific project questions.
The process illustration supports scope discussion. The XGF equipment image is reproduced from page 9 of the Allot Tech 2026 catalog; use the catalog and project documents to review the applicable configuration.
Buyer questions
Frequently asked questions
Is a water deaerator enough to control all package oxygen?
No. Ingredients, tanks, transfer, filling and headspace can affect the final result. Review the complete process and package boundary.
Can the same oxygen target be used for water, tea and carbonated drinks?
The responsible product specialist should define the target for each product and test method. Do not assume a universal limit.
What should a deaeration RFQ include?
Include feed conditions, flow range, outlet requirement, measurement location, utilities, cleaning interface, control scope and acceptance conditions.
