Focus keyword: boiler demineralized water project
Xi'an Thermal Group, a major district heating provider in Xi'an, China, needed high-purity feedwater for its high-pressure boilers. Dissolved salts and silica can cause scaling, corrosion, and costly downtime, while traditional ion exchange requires acid and alkali regeneration.
Solution: A 360 m³/h RO + EDI demineralization system. Two-stage reverse osmosis removes most dissolved ions, and EDI polishes the water to conductivity below 0.1 μS/cm — without chemical regeneration.
Results:
Stable high-purity boiler feedwater
No waste acid or alkali discharge
Lower operating cost and environmental risk
Reliable supply for district heating boilers
Key takeaway: For large boiler demineralized water projects, RO + EDI is a green, reliable alternative to conventional ion exchange.
