Condensate Polishing is a process deployed to remove contaminants from condensate streams like steam, turbine and process condensate, before it is returned to the boiler/heat exchangers. It is highly important to remove traces of soluble inorganic impurities present in the feed water, as they may get concentrated within the system.
Ion exchange resins used in condensate polishers mainly serve two purposes:
- Removal of suspended solids by filtration more
- Removal dissolved solids by ion exchange
