DLEM · Water-process module
Concentrates lithium selectively from an independently accepted lithium-bearing water and keeps product solution, raffinate and service residuals separate.
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.
Source and DLEM inlet criteria accepted.
Guard state and feed route valid.
Cycle, flow and media state inside released basis.
Wash and elution identities and destinations proven.
Each receiver criteria met.
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 |
|---|---|---|---|
| Accepted lithium-bearing water | Inlet | Qualified source / PWCM → DLEM | Complete analysis, variability and pretreatment state accepted. |
| Lithium-rich solution | Product / intermediate | DLEM → named product receiver | Concentration, chemistry, flow and receiver defined. |
| Raffinate | Raffinate | DLEM → WPRM or named receiver | Composition, route and water destination accepted. |
| Wash / regenerant / spent media | Residual | DLEM → separate receivers | Chemistry, containment and ownership defined. |
| Off-spec product | Off-spec | DLEM → hold or reprocess | No mixing with released product. |
Published datasheet
Unsupported values are never guessed. The table states either the current public definition or exactly how the value is established.

| Materials | Selected from brine chemistry, reagents, temperature and cleaning. | Project-specific |
| Controls | Feed, media state, cycle identity and separate stream routes are verified locally. | Fixed architecture |
| Recovery / selectivity / cycle life | Requires representative-water validation; not published as a product constant. | Not publicly released |
Interface schedule
Process, utility, residual and control handovers are listed separately so responsibility is visible.
| Interface | Class | Handover | Acceptance evidence |
|---|---|---|---|
| Qualified-water inlet | Process in | Accepted lithium-bearing water | Pretreatment, analysis and variability basis. |
| Lithium-product outlet | Product | Lithium-rich solution | Named receiver specification. |
| Raffinate outlet | Process out | To WPRM or named receiver | Chemistry and water route accepted. |
| Reagent / residual | Utility / residual | Wash, elution, regenerant and spent media | Supply and waste routes released. |
| Automation | Controls | Cycle, media, route and quality evidence | Local sequence and feedback 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 | DLEM accepts only an independently qualified lithium-bearing water. | Source, pretreatment, flow, chemistry and variability. |
| Kit / chemistry | Selected capture and release chemistry has its own qualified limits. | Lithium, competing ions, organics, scaling, reagents and temperature. |
| Module | Installed media and cycle configuration define local limits. | Flow, loading, wash, elution, pressure drop and media state. |
| Receiver | Product, raffinate and residuals are released separately. | Quality, route, capacity and off-spec handling. |
Safety, cleaning and lifecycle
Safe state, cleaning, maintainability and evidence gates are part of the technical definition, not afterthoughts.
