Concentrate management, brine pre-concentration, thermal screening, crystallization and solids pathways.
- FO pre-concentration
- Falling-film evaporator screening
- Crystallization and recovered-water/solids pathways
Development / planned capability
- Arbitrary-order coupled train, multi-effect energy cascade and rigorous high-molality properties
- Multi-salt crystallization and optimization after model validation
Required inputs
Brine flow, composition, concentration target, energy/recycle basis, tube geometry and vendor or user property assumptions.
Main calculated outputs
Screening water/solids/recycle/energy discussion, mass balance, duty, area, tube count and warnings.
Assumptions and defaults
Vendor data, correlation applicability and constraints are stated per case.
Known limitations
In Development. FFE correlation is limited to its disclosed range; no full MEE cascade or final mechanical exchanger design.
INTEGRATION ROLE AND MATURITY
Progressive integration, clearly disclosed.
Selected concentrate or residual streams may form a downstream ZLD basis with preserved provenance and maturity.
Illustrative engineering capacity returned
8–28 h ZLD screening and configuration study
Illustrative planning assumption—not a measured customer outcome or guarantee. Actual time depends on project complexity, data quality, current tools, alternatives, review requirements and user experience.
Sample-report state
ZLD falling-film evaporator screening sample state: planned publication. Validated, sanitized sample artifacts are currently unavailable; publication is planned. No downloadable evidence is implied.
ZLD screening boundaries
FFE engineering preview applies only to 280–305 K, 35,000–95,000 mg/L, Reynolds number 45–90 and Prandtl number 5–10. It is a horizontal-tube correlation, not a universal VFFE model.
Out-of-range FFE cases require a separately validated design U and are never silently extrapolated. Tube mechanical design is vendor scope; hypersaline or unconventional feeds may require pilot and/or vendor data.
Crystallization is screening only: supersaturation, growth/nucleation, residence time, solids production, mother-liquor recycle/purge, forced-circulation duty, inhibitor effects and downstream solids all require equipment/customer-release validation. Multi-salt behavior and sequence remain validation boundaries. Non-condensables, vacuum, entrainment, vapor body, shell/tubesheet, metallurgy and fabrication are excluded.
