Tertiary treatment and membrane bioreactors, proven to a fit-for-purpose standard
Commissioning software for industrial water reuse schemes where tertiary treatment, membrane bioreactors and cross-connection control all have to prove out before reclaimed water reaches an industrial process.
An industrial water reuse scheme reclaims effluent or process wastewater to a fit-for-purpose standard for cooling, process make-up or irrigation, adding tertiary filtration, membrane bioreactors or advanced oxidation on top of conventional treatment, with strict cross-connection control between potable and reclaimed systems. Deskely holds every membrane train, dosing skid and cross-connection point in one register with the water-quality-validation and cross-connection-control gates built in.

The problem
Reclaimed water shares a site with potable water, and a spreadsheet cannot prove that every cross-connection point has actually been tested.
A reuse scheme adds membrane bioreactors, tertiary filtration or advanced oxidation to an existing treatment stream, and it has to coexist on site with a potable supply, with backflow prevention and clearly tagged cross-connection points carrying real consequences if missed.
When membrane integrity tests, dosing calibration and cross-connection verification sit in separate contractor sheets, nobody can confirm before reclaimed water is released to an industrial customer that every backflow prevention device has actually been tested, not just installed.
Deskely tags every membrane train, dosing skid and cross-connection point individually, so fit-for-purpose readiness is reported from verified test data rather than assumed from an installation checklist.
Setting up the register
MBR trains, dosing skids and cross-connection points are tagged assets matched to the process design and cross-connection control plan.
P&IDs, membrane train drawings and the cross-connection control plan are parsed into a reviewed register, so every train, dosing skid and backflow prevention device carries its process duty and its cross-connection reference from day one.
Dry commissioning, membrane integrity testing and disinfection dosing templates are defined once per asset type and instantiated across every train, while cross-connection verification is held as its own distinct test type.
Reclaimed water quality parameters agreed with the end user — turbidity, pathogen indicators, specific process chemistry — sit in the same register, so quality validation is derived from the same evidence as mechanical commissioning.
Execution
Membrane proving, disinfection and cross-connection testing are gated before reclaimed water is released to the customer.
MBR and tertiary filtration trains are wet commissioned and integrity tested, with disinfection dosing proven to the contact time and dose the reuse standard requires before the train is cleared to feed the reclaimed water main.
Every backflow prevention device and air gap at a cross-connection point is functionally tested and tagged, with the test result attached to the specific point rather than a general site statement that cross-connection control is in place.
Vendor punch from the membrane supplier and the dosing skid OEM is logged at the specific train, so a delay on one train does not block release of reclaimed water already proven on another.
Fit-for-purpose sign-off and handover
Reclaimed water is released from proven quality and cross-connection control, not from an assurance that the design intent was followed.
Fit-for-purpose sign-off draws on the same membrane integrity, disinfection dosing and cross-connection verification records built during commissioning, so the evidence the industrial customer and the regulator require is an export rather than a rebuild.
The handover pack for the operations team includes as-built P&IDs, membrane specifications and the verified cross-connection control plan keyed to the register, ready for operations from the day reclaimed water is first supplied.
Every signature carries a name, role and timestamp, which is what the water quality regulator and the industrial customer's risk assessment expect before reclaimed water is declared fit for its intended use.
The dossier
Records that stop reclaimed water crossing into a potable system.
A reuse scheme shares a site with a potable supply, so the dossier has to be built around two separate proofs: that the membrane train reaches fit-for-purpose quality, and that every cross-connection point has actually been tested, not just installed to the design.
Membrane bioreactor integrity test certificate
MBR or tertiary membrane trains pass integrity testing with no detectable fibre breach before feeding the reclaimed main.
Performed before a train is first cleared to supply reclaimed water.
Disinfection dose and contact time record
UV or chemical disinfection achieves the dose and contact time the reuse standard specifies for the intended end use.
Captured during wet commissioning of the disinfection stage.
Cross-connection and backflow prevention test record
Each backflow preventer or air gap at a cross-connection point functions correctly to stop reverse flow into the potable main.
Tested individually at every tagged cross-connection point before release.
Reclaimed water quality validation certificate
Turbidity, pathogen indicators and any process-specific chemistry meet the standard agreed with the industrial end user.
Compiled from sampling once the treatment train is in stable operation.
Cross-connection control plan verification record
The as-tested cross-connection control plan matches the design plan, with every point accounted for and signed.
Assembled once every cross-connection point has an individual test result.
Fit-for-purpose release certificate
Water quality validation and cross-connection control are both proven, clearing reclaimed water for release to the customer.
Signed before reclaimed water is first supplied to the industrial process.
How it runs
From membrane commissioning to a verified cross-connection plan.
Reuse schemes reward a register that treats every cross-connection point as its own tested asset, because a missed backflow prevention test is exactly what a water quality incident review will find first.
