Ultrafiltration (UF) Engineering
UF is the low-pressure membrane stage usually placed ahead of RO or NF. EngiMetric models the sizing and operating quantities that are defined by conservation and by the standard membrane identities — everything empirical (design flux, pressures, measured flux) is supplied by you.
Choose a calculation below. Each one runs an EngiMetric UF engine and reports its own validation; no design limit is assumed on your behalf.
UF membrane area
EngiMetric engine
Runs calculateUfMembraneArea. Every value below is calculated by that engine; the
Copilot never supplies engineering values.
Inputs the engine needs, and why
- Feed flow (m³/h) — Membrane area is sized from the flow that must pass through the membrane.
- Design flux — Membrane area is only defined against a flux basis, so the design flux must be supplied.
UF transmembrane pressure
EngiMetric engine
Runs calculateUfTmp. Every value below is calculated by that engine; the
Copilot never supplies engineering values.
Inputs the engine needs, and why
- Feed pressure — Transmembrane pressure needs the feed, concentrate and permeate pressures.
- Concentrate pressure — Transmembrane pressure needs the feed, concentrate and permeate pressures.
- Permeate pressure — Transmembrane pressure needs the feed, concentrate and permeate pressures.
UF flux condition
EngiMetric engine
Runs calculateUfFluxCondition. Every value below is calculated by that engine; the
Copilot never supplies engineering values.
Inputs the engine needs, and why
- Design flux — Membrane area is only defined against a flux basis, so the design flux must be supplied.
- Current flux — The observed flux is the value being compared with the design basis.
