Choose the combination of reuse, storage and heat recovery that lowers total intake without stockouts, cross-contamination or capacity loss.
Independent model study · brewery water network
Reduce brewery water intensity without creating a hot-water shortfall

Decision model
A bounded question with a complete plant consequence.
Brewhouse through packaging plus raw/process water, hot-water tank, deaerated water, cooling tower, CIP supply/return, product loss and wastewater.
Equations and accounting rules
Water intensity = site water intake / packaged beverage volumedV hot water/dt = recovered inflows − scheduled usersHeat recovery = mass flow × Cp × temperature changeCooling makeup = evaporation + blowdown + driftBase, alternative and stress cases
- Rinse recovery and conductivity endpoint
- Larger hot-water tank
- Improved heat recovery and DAW reuse
- Higher cooling cycles and 10% growth
Engineering brief
Model the complete decision, not an isolated unit operation.
Carlsberg publicly reports water-intensity metrics and intervention categories including CIP optimisation, hot-water balancing, deaerated water and cooling-tower savings.
The model uses those public categories as a roadmap, not a claim about a particular brewery. Recipes, meters, sanitation limits and tariffs require operator evidence.
01 · Model basis
What the Acatian model needs to resolve
Inputs, mechanisms, limits and outputs remain reviewable on one declared basis.Inputs
Brew size, recipes and packaged volume
CIP sequence, endpoints and return quality
Wort-cooling and hot-water temperature profiles
DAW, cooling-tower and wastewater meter data
Mechanisms
Water intensity = site water intake / packaged beverage volume
dV hot water/dt = recovered inflows − scheduled users
Heat recovery = mass flow × Cp × temperature change
Cooling makeup = evaporation + blowdown + drift
Constraints
Cleaning sequence and validated quality
Hot-water inventory and temperature
Shared CIP sets and tank schedules
Packaging output and water restrictions
Outputs
hl water per hl packaged beverage
Area use and hot-water stockout hours
CIP conflicts, steam and cooling
Beer loss, wastewater and payback inputs
02 · Acatian workflow
Build it in six controlled steps
Each step creates a reviewable object, not a hidden spreadsheet assumption.- 01
Map every water source, sink and meter.
- 02
Close beer, extract and water balances.
- 03
Add CIP recipes and quality states.
- 04
Schedule hot-water recovery and demand.
- 05
Model DAW and cooling-tower alternatives.
- 06
Rank robust savings without sanitation compromise.
03 · Decisions
Questions the model should answer
Where is water actually consumed?
Is storage or recovery limiting?
Which CIP return is safe and valuable?
Does growth create a new utility peak?
04 · Evidence boundary
Validate before the result carries weight
Validation
Reconcile meters, packaged volume, temperature, CIP events, product loss and wastewater over representative weeks; test peak as well as average conditions.
Limitations
Group metrics are public benchmarks, not a site baseline. The model does not replace food-safety, cleaning-validation or water-regulatory review.
Public evidence
What the company context supports—and what it does not.
Sources establish the public process architecture. They do not reveal private operating parameters, site performance or an Acatian relationship.Frequently asked questions
Practical modelling questions
Is this the named organisation's real plant model?
No. It is an independent hypothetical Acatian study based only on the cited public process architecture. It claims no affiliation, endorsement, deployment, confidential data or actual plant performance.
Where do the numerical inputs come from?
Every input must be marked as a public fact, literature estimate, transparent engineering assumption or authorised customer input. The public article does not invent private operating values.
Can the model be calibrated to a real facility?
Yes, when the operator supplies authorised process, equipment, schedule and utility evidence and agrees the intended use, acceptance criteria and validation plan.
