    Ion exchange removes dissolved ions from water with near-perfect selectivity, achieving conductivities below 0.1 microsiemens per centimetre that RO alone cannot reach. But at feed TDS above 500 mg/L, the regenerant cost makes it uneconomic without pre-treatment. The complete guide to sizing, configuration, and the RO versus IX versus hybrid decision.
