Power Plants

• Scaling and Deposition: Dissolved minerals such as calcium, magnesium, and silica cause scale deposits on boiler tubes, reducing heat transfer efficiency and increasing energy consumption.
• Corrosion: Dissolved gases like oxygen and carbon dioxide in feedwater lead to corrosion of boiler and steam systems, resulting in damage and reduced equipment lifespan.
• Carryover and Foaming: Impurities, along with foam caused by high dissolved solids, lead to carryover in steam, causing deposits in turbines and other equipment.
• Silica and Sodium Contamination: High levels of silica and sodium in feedwater contribute to deposition on turbine blades and other steam system components.
• Iron and Copper Oxides: Corrosion of feedwater and condensate return systems introduces iron and copper oxides, which can deposit in boilers and steam lines.

• Oxygen Scavengers: Removes dissolved oxygen using chemicals such as hydrazine, sulfite, or their alternatives.
• Corrosion Inhibition: Protect metal surfaces from oxidation and corrosion and ensures pH control and minimizes corrosion with use of amines, phosphates, or specialized filming inhibitors.
• Anti-Foam Agents: Add antifoaming chemicals to the boiler water treatment program Prevent foaming that leads to steam impurities and carryover and increase cycles of concentrations and reducing blowdown and energy loss.

• Reverse Osmosis: Achieve ultra-pure water by removing dissolved solids by using reverse osmosis membranes for feedwater pre-treatment.
• CEDI (Continuous Electrodeionization) and Mixed Bed Polishing: Use CEDI and mixed-bed resin systems for final polishing to achieve extremely low levels of ionic contamination to produce ultrapure water for high-pressure boilers.
• Condensate Polishing: By employing an ion exchange resin or filtration systems to maintain high condensate purity by removing dissolved impurities such as silica and metals (iron, copper).
• Conductivity/ Silica/ Sodium Monitoring: Use online conductivity meters to detect contamination and trigger corrective actions by continuously monitoring condensate and feedwater purity to prevent turbine blade deposits.
• Blowdown Systems: Automated blowdown controls optimize water removal while maintaining boiler efficiency to minimize dissolved solids and prevent scale and carryover.
