Water chemistry for power plant reliability.
Product selection depends on raw water quality, plant type, pressure class, metallurgy, cooling configuration, RO design, wastewater profile and site operating strategy.
Analysis First
Water analysis before product recommendation.
TDS, SDS and certificates are shared upon request.
Power plants rely on water across steam generation, high-pressure boilers and HRSG units, cooling towers and condensers, closed-loop auxiliary cooling, RO and demineralization, and wastewater including FGD and blowdown streams. Liberta matches PureGuard® and BlancoWT® programs to each system based on water analysis, system design, pressure class, metallurgy, operating conditions and site-specific risks. For RO and demineralization, RO-Watel supports product and dosage selection; for eligible boiler, cooling and closed-loop systems, WATEL Analyses provides data-based technical service support when periodic field data are available; and wastewater is treated through BlancoWT® and Jar Test Services.
Typical water-related problems
| Problem | Why It Matters | Response |
|---|---|---|
| Oxygen corrosion | Feedwater, pre-boiler sections, condensate return. | Can damage carbon steel systems and increase corrosion product transport. |
| Silica / iron / hardness leakage | High-pressure boiler and HRSG make-up systems. | Can increase deposit sensitivity and affect steam-side reliability. |
| Scale and condenser deposition | Cooling towers, heat exchangers, condensers. | Reduces heat-transfer efficiency and increases operational stress. |
| Membrane fouling and scaling | RO and demineralization pretreatment. | Affects boiler make-up reliability and cleaning frequency. |
| Biofilm and microbiological tendency | Cooling water, closed loops under suitable temperature, stagnant sections. | Can contribute to fouling, corrosion tendency and heat-transfer loss. |
| Sludge and blowdown burden | Boiler blowdown, cooling blowdown, FGD wastewater. | Raises wastewater load and sludge-handling demand. |
| Foam and separation instability | Wastewater, aeration tanks, DAF or separation units. | Can affect overflow risk, separation efficiency and operator control. |
System mapping
| System | Risk | Solution |
|---|---|---|
| High-pressure boiler / HRSG | Silica, oxygen, iron, pH, condensate corrosion, carryover. | PureGuard® boiler chemistry program; high-purity review; selected AVT/phosphate-free route where applicable. |
| RO / demineralization | Scaling, SDI/turbidity, fouling, incorrect antiscalant dosage. | BlancoWT® pretreatment, PureGuard® 7-series antiscalants including selected P-Free options, PureGuard® 3-series cleaning, RO-Watel. |
| Cooling tower / condenser | Scale, corrosion, suspended solids, microbiological tendency, blowdown control. | PureGuard® cooling programs including P-Free Green Chemistry and no-added-heavy-metal options where applicable. |
| Closed-loop auxiliary cooling | Mixed-metal corrosion, low inhibitor residual, glycol degradation, low-temperature microbiological risk. | PureGuard® closed-loop corrosion/scale inhibitors, biocide options below 55-60°C, flushing/cleaning support. |
| Process and auxiliary water | Process-specific deposits, pH/corrosion, recycled water variation. | Site review + PureGuard® or BlancoWT® product matching depending on water role and root cause. |
| Wastewater / FGD / blowdown | TSS, turbidity, metals, foam, oily load, sludge dewatering. | BlancoWT® coagulants, flocculants, AntiFoam, Color Removal, Emulsion Breaking where applicable, Jar Test Services. |
