Ion Exchange (IX / IER) Engineering
Ion exchange resins polish a stream by exchanging dissolved ions. EngiMetric sizes a bed from the resin capacity, bed depth and influent load that you supply, and derives EBCT, service flow, breakthrough volume and regenerant demand. No resin capacity or chemical dosage is assumed.
Choose a calculation below. Each one runs an EngiMetric IX engine and reports its own validation; resin and regenerant properties are always your inputs.
IX resin bed sizing
EngiMetric engineEvery value below is produced by the registered EngiMetric engine for this calculation. The Copilot never supplies engineering values.
Inputs the engine needs, and why
- Flow (m³/h) — Bed volume and EBCT are defined against the flow the bed must treat.
- Resin working capacity (eq/L) — Capacity is a property of the selected resin. Supply the published value; EngiMetric does not assume one.
- Bed depth (m) — Depth is an engineering choice from the resin data; supply it rather than accepting a default.
- Influent load (meq/L) — The ionic load carried to breakthrough is the sizing basis.

IX regeneration demand
EngiMetric engineEvery value below is produced by the registered EngiMetric engine for this calculation. The Copilot never supplies engineering values.
Inputs the engine needs, and why
- Volume to breakthrough (m³) — Regenerant demand is proportional to the loading taken to breakthrough.
- Influent load (meq/L) — The loading equals the influent concentration times the throughput volume.
- Regenerant strength (% w/w) — Strength converts regenerant mass into solution volume. Supply the strength actually used.
- Regenerant molar mass (g/mol) — Molar mass is required for stoichiometry; EngiMetric does not assume a chemical.
