Effluent Treatment Plant for Power Plants

Power plants generate wastewater from boiler blowdown, cooling tower bleed-off, DM plant regeneration, ash handling, and equipment washing. RRR ENVIRO SYSTEMS designs high-efficiency ETPs that meet CPCB / TNPCB discharge norms with minimum chemical usage and maximum water recovery.

Sources of Wastewater in Power Plants

• Cooling tower blowdown
• Boiler blowdown & condensate
• DM plant regeneration wastewater
• Coal / fly ash handling & slurry
• Oil & grease-contaminated wastewater
• Turbine & equipment wash water

Typical Pollutants

• High TDS & TSS
• Silica, phosphates & hardness
• Heavy metals (Fe, Cu, Mn, etc.)
• Oil & grease
• High pH / alkalinity
• Chlorides & sulphates

ETP Process Flow

1. Collection & Equalization Tank
2. pH Correction & Chemical Dosing
3. Primary Clarifier
4. Oil Skimmer / O&G Trap
5. MBBR / ASP Biological Treatment (if organic load exists)
6. Secondary Clarifier
7. Pressure Sand Filter (PSF)
8. Activated Carbon Filter (ACF)
9. UF + RO (for Zero Liquid Discharge)
10. Evaporator / ATFD (Optional for ZLD)
