Water Management for Power Plants
Power generation facilities require extensive water treatment for cooling systems, boiler feed, flue gas desulfurization (FGD), and ash handling. Our solutions are engineered for the high-volume, continuous operation demands of power plants with reliable, low-maintenance equipment. From cooling-water and boiler-feed treatment to flue-gas desulphurisation and ash-water handling, each duty is engineered for high-volume, continuous, low-maintenance service. Reynolds & Bauhm integrate these systems so the whole station meets its water-quality and discharge obligations dependably.

Explore Power Waste EnergyFrom boiler makeup to FGD purge — the chemistry behind each loop
| Stream | Conductivity / TDS | Key Quality Limit | Typical Contaminants | Treatment Driver |
|---|---|---|---|---|
| Boiler makeup (high-pressure) | < 0.1 µS/cm | SiO2 < 20 µg/kg; Na < 5 µg/kg (ASME) | Hardness, silica, dissolved O2, organics | 2-pass RO + EDI + polish |
| Condensate polishing | 0.05 – 0.5 µS/cm | Na < 5 µg/kg; Cl < 5 µg/kg | Iron oxides, condenser leak salts, amine residual | Mixed-bed ion exchange; deep-bed filters |
| Cooling tower blowdown | 1,500 – 10,000 µS/cm | LSI < 0; cycles 3–7 | Ca/Mg hardness, sulphate, biocides, phosphonate scale inhibitor | Side-stream softening; cycles control |
| FGD purge / wet scrubber bleed | 20,000 – 60,000 µS/cm | EPA ELG: Se <12 µg/L, Hg <39 ng/L, NO3+NO2 <4.4 mg/L | Cl− 5,000–25,000; SO42−; Hg, Se, As; CaSO4 saturated | Bio-treatment + sulphate precipitation; ZLD |
| Ash sluice / pond return | 1,500 – 5,000 µS/cm | EPA ELG bottom-ash transport: zero discharge by 2025 | Trace metals (As, Se, B), high alkalinity, fly-ash leachate | Dry handling preferred; closed-loop |
| Coal-pile runoff | 500 – 3,000 µS/cm | pH 6–9; TSS <30 mg/L | Acidic from pyrite (FeS2) oxidation; Fe, Mn, sulphate | Neutralisation + clarification |
| Demin regen / IX waste | variable (acid/caustic) | pH 6–9 for discharge | HCl, NaOH, dissolved Ca/Mg/Na | Neutralisation tank with mixed regen wastes |
| Plant area / oily drains | seawater or low | Oil < 5–15 mg/L | Lube oil, hydraulic fluid, turbine oil | API separator + coalescer / DAF |
Cycles-of-concentration: The cooling tower water balance is N = Cblowdown/Cmakeup. Higher N cuts blowdown volume but raises scaling/corrosion risk. Practical envelope: N = 3–5 for poor makeup, 5–7 with softened/RO permeate, up to 10+ with full ZLD trains.
