Thermal Desalination

Vapour-compression and multi-effect processes.

Heat-driven processes that separate salt by evaporation and condensation. Catalogued for orientation only: EngiMetric has no thermal desalination engine and states no energy or performance figures for these technologies.

Engineering Disclaimer & Verification Notice

This calculator provides preliminary engineering estimates for informational and planning purposes. Actual reverse osmosis / engineering system performance depends on site conditions, feed-water chemistry, membrane characteristics, operating pressure, temperature, recovery limits, fouling/scaling potential, and system design. Verify results using project-specific data, manufacturer projections, and applicable engineering standards before final design or operation.

Calculators for this area

RO Energy & Specific Power CalculatorDetermine specific energy consumption (kWh/m³) based on operating pressure and pump efficiency, with optional energy recovery device savings.
Small & Modular Desalination SizingSize a small or modular desalination plant from a demand basis forward: community population to product flow, then feed and concentrate by the plant mass balance, then membrane area, vessels and staging. Composes engines that already exist; chooses no recovery, staging ratio, flux or package envelope.
Filter Sizing CalculatorSize a conventional rapid-gravity multimedia filter from design flow, filtration rate, bed depth and media effective size: required filter area, design area after the engineer's safety factor, and media volume. The unit count needs a stated catalogue unit area, and no clean-water head loss is invented.
Desalination Plant DesignerCompose a whole desalination plant as an ordered chain of unit operations from raw intake to product and waste: design basis, stage recoveries and make-up, whole-plant water and salt balance checks, and concentrate TDS derived by salt conservation — every value labelled input, derived or missing.
Pipe Thermal Expansion CalculatorFree linear expansion of a pipe run for a given material, length and temperature rise, in millimetres and per 100 m.
Solar Thermal Collector Area CalculatorSize a flat-plate solar thermal collector from a heat balance — once for the daily hot water demand and once for the peak hour — and see which one actually governs.

EngiMetric describes these technologies and states their maturity, but does not size them. Sizing figures for this area come from a process vendor or a specialist calculation — the platform will not produce them.
