Condensate Polishing Unit

What is the working principle of Condensate Polishing Unit (CPU)?

A Condensate Polishing Unit (CPU) plays an important role in maintaining the quality of feedwater in industrial steam systems. Their main function is as follows:

- Membrane Filtration: CPUs use membranes such as RO or NF to filter out contaminants such as organic and inorganic components, dissolved ions, hardness precursors, suspended solids etc.

- Ion Exchange: Specifically designed Ion Exchange Resin (IEX) resin beds replace undesirable ions with harmless ones, effectively demineralizing the feed.
- Corrosion and Scale Prevention: CPUs assist in controlling corrosion and scaling in boilers and turbines by using specifically tuned antiscalants, biocides, and corrosion inhibitors.

- Efficiency Improvement: High-quality feedwater improves heat transfer rates in boilers and heat exchangers giving better operational efficiency.

- Reduce Maintenance: With reduced impurities, there is operational downtime, leading to lower maintenance costs.

- Safety: Minimizing scale and corrosion enhances the safety of the system by reducing the risk of failures.
