WPRM · Water-process module
Builds a receiver-specific water polishing and reuse train from one or more transportable process cells, with explicit product-water and residual ownership.
Module function
The functional boundary is explicit so a module is never treated as a universal process claim.
How the module works
Each step names both the physical function and the evidence required before the next handover.
P0 feed and receiver basis accepted.
Feed state and available capacity verified.
Barrier state and route valid.
Selected treatment state completed.
Quality, route and receiver evidence recorded.
Stream schedule
A stream is not released merely because the equipment can move it. Its state, route and receiving boundary must be accepted.
| Stream | Direction | Physical handover | Acceptance / release basis |
|---|---|---|---|
| Named aqueous feed | Inlet | PWCM, DLEM raffinate or independent accepted source → WPRM | Complete analysis, flow, variability and source identity. |
| Candidate product water | Product | WPRM → authorised named receiver | Receiver-specific quality and release evidence. |
| Concentrate / backwash | Residual | WPRM → separate residual receiver | Composition, flow, capacity and ownership. |
| Spent media / cleaning | Residual | WPRM → named lifecycle receiver | Hazard, containment and disposal / regeneration route. |
| Off-spec water | Off-spec | WPRM → hold, recycle or residual receiver | No automatic release or potable claim. |
Published datasheet
Unsupported values are never guessed. The table states either the current public definition or exactly how the value is established.
| Specification field | Current definition | Evidence basis |
|---|---|---|
| Product code | WPRM | Fixed architecture |
| Product family | Water-process module | Fixed architecture |
| Typical process position | Water-route finishing | Fixed architecture |
| Product form | One or more transportable process cells selected around one feed and one receiver. | Fixed architecture |
| Barrier train | Equalisation, guard, primary barrier, polish and conditioning / disinfection selected by case. | Configuration option |
| Flow / turndown | Established from confirmed source and receiver demand. | Project-specific |
| Water-quality basis | Complete representative analysis compared with named receiver limits. | Project-specific |
| Utilities / consumables | Mass balance and selected barrier configuration define power, water, air and chemicals. | Project-specific |
| Materials | Selected from complete water and cleaning chemistry. | Project-specific |
| Controls | Barrier state, quality hold, residual route and receiver release are verified locally. | Fixed architecture |
| Product-water performance | Verified against the named receiver; not a universal or automatic potable release. | Project-specific |
Interface schedule
Process, utility, residual and control handovers are listed separately so responsibility is visible.
| Interface | Class | Handover | Acceptance evidence |
|---|---|---|---|
| Water inlet | Process in | One named accepted feed | Source, flow and complete analysis. |
| Product-water outlet | Product | Authorised named receiver | Receiver quality and release evidence. |
| Residual outlets | Residual | Concentrate, backwash, spent media and cleaning | Separate owned receivers. |
| Site services | Utility | Services required by selected cells | Quality, availability and failure behaviour. |
| Automation | Controls | Barrier, quality, hold, diversion and receiver evidence | Local cause/effect tested. |
Operating envelope
The system envelope, Kit or chemistry limits, installed module configuration, project evidence and receiver criteria all apply. The narrowest valid limit governs.
| Envelope layer | Governing rule | Checks before release |
|---|---|---|
| Product | One named feed and one named receiver anchor each P0 case. | Source, flow, analysis, variability and receiver limits. |
| Module | Selected barriers and process cells define installed operating limits. | Hydraulics, pressure, fouling, scaling, backwash and consumables. |
| Project | Representative evidence defines the qualified train and release window. | Barrier challenge, residual mass balance, quality and availability. |
| Receiver | Release is receiver-specific and may require authorisation beyond Elemenos. | Quality, monitoring, legal/site permission and off-spec diversion. |
Safety, cleaning and lifecycle
Safe state, cleaning, maintainability and evidence gates are part of the technical definition, not afterthoughts.
