01 Answer first
What must be controlled between final water treatment and the filler?
Control tank turnover, recirculation, hygienic connections, vents, drains, sampling, level and quality logic, filler and treatment interlocks, cleaning, abnormal product status, and stop-restart behavior under the approved process plan.
02 Where it fits
Position in the project journey
Hygienic process integration — before tank, piping, controls, and filler connections are released.
03 Buyer inputs
What the buyer should prepare
- Approved product-control and sampling plan
- Cleaning and release procedures
- Local hygienic and piping review
04 Allot Tech and manufacturing-resource inputs
What should be clarified or provided
- Tank, loop, instrument, and control design
- Operating-mode logic
- Cleaning and maintenance interfaces
Allot Tech coordinates requirement, quotation and project communication. Detailed engineering, manufacture, testing, documentation and confirmed service are performed by selected manufacturing resources according to the signed scope.
05 Technical scope
Questions and work to control
Define the Treated-Water Quality Boundary
Link the tank and loop to the approved water category, treatment endpoint, control plan, filler requirement, and qualified local food-safety decisions.
Model Tank Working Volume and Turnover
Review usable volume, refill rate, filler demand, low-production periods, recirculation, minimum level, high level, and prolonged-stop scenarios.
Design Hygienic Connections and Access
Coordinate tank surfaces, inlet and outlet arrangement, vent, overflow, drain, sample, spray device where selected, instruments, access, and inspection.
Control Distribution and Return Paths
Define loop routing, branch conditions, flow direction, recirculation, dead-leg review, isolation, filler interface, and response when downstream demand stops.
Set Level, Flow, and Quality Logic
Identify permissives, alarms, pump control, valve states, treatment calls, filler interlocks, quality status, and authorized manual actions.
Plan Cleaning and Return to Service
Specify isolation, drain-down, cleaning sequence, contact boundaries, rinse or verification requirements, sample status, and release authority in site procedures.
Provide Representative Sampling and Records
Qualified parties should choose sample locations, instruments, calibration, trends, laboratory work, and the action taken when evidence is outside the approved basis.
Verify the System Under Stop and Restart Cases
Test production, standby, filler stop, treatment stop, tank high or low, cleaning, utility loss, abnormal status, and controlled restart interfaces.
Buyer questions answered
Practical answers before you request a quotation
Is more treated-water storage always useful?
No. Storage affects turnover, control, cleaning, space, and response to low demand or abnormal status.
Why test a filler-stop case?
Downstream stops change demand, tank level, recirculation, treatment calls, and product-status decisions.
Who sets final sampling requirements?
Qualified local laboratory, food-safety, treatment, and regulatory parties should define them.
06 Responsibility
Assign the owner before the work is due
Land, building and civil work, permits, import and customs, local taxes, site utilities, unloading, lifting, local labor, travel support and commissioning materials are not automatically included. Confirm every responsibility before order.
07 Common risks
What commonly creates avoidable uncertainty
- Low demand creates unmanaged stagnation
- Overflow or vent design crosses a contamination route
- Manual actions bypass product-status control
08 Acceptance or completion
How to know the stage is complete
Approve when hygienic design, turnover, controls, cleaning, sampling, abnormal response, and functional evidence agree across the complete system.
09 Required documents
Records that support the decision
- Treated-water flow diagram
- Tank and loop control narrative
- Functional-test record
