CPU System for Boiler Feed Water Protection
The Condensate Polishing Unit receives hot returned condensate from the steam cycle and removes suspended iron oxide, copper oxide and ionic leakage before the condensate returns to the deaerator or boiler feed system.
WTE combines cartridge filtration, precoat filtration, cation resin, anion resin, mixed bed polishing, external regeneration and PLC control to maintain low conductivity and stable cycle chemistry.
Condensate Collection & Pre-FiltrationReturned condensate is routed through strainers, cartridge filters or precoat filters to capture suspended corrosion products.
Ion Exchange Polishing ZoneCation, anion or mixed bed resin removes sodium, silica, chloride, sulfate and conductivity-causing dissolved impurities.
Resin Regeneration & RinseExhausted resin is regenerated using acid and caustic systems with rinse sequencing for restored exchange capacity.
Boiler-Ready Condensate OutputPolished condensate is returned to the feed water circuit with reduced contamination risk and improved DM water recovery.

Working Process
How a Condensate Polishing Unit Works
CPU treatment removes corrosion products and dissolved ions before condensate returns to the boiler circuit.
1
Condensate Inlet & Pre-Filtration
Returned condensate passes through strainers, cartridge filters or precoat filters to remove suspended iron oxide, copper oxide, rust particles and fine corrosion products.
2
Cation / Anion Exchange
Dissolved ions such as sodium, chloride, sulfate and hardness leakage are removed through selected cation and anion resin beds to control conductivity and ionic contamination.
3
Mixed Bed Resin Polishing
Mixed bed resin delivers final polishing for silica, sodium and conductivity reduction, producing high-purity condensate suitable for boiler feed water return.
4
Monitoring, Regeneration & Return
Online conductivity, pressure drop and optional silica/sodium signals guide service, rinse and regeneration cycles. Polished condensate is then returned to the boiler feed circuit.
