In addition, emergency or planned temporary water treatment services are also available in many countries.

Creating Water solutions for the Power Generation Industry

Pre-treatment

PRE-TREATMENT TARGETSRemoval of suspended solids, colloidals, organics, iron and manganese from water.

Screening

Settling, clarification

Combined clarification + filtration

Softening

Catalytic lime softening: fluidized bed separation

Sea water feed

Settling, clarification

Flocculation, sedimentation

Membrane technologies

Electro-chlorination

Desalination for make-up water and process water

Boiler feed water

Veolia Water Technologies designs, installs and commissions water treatment systems for power generation plant steam generators. Impurities entering the boiler system cause reduced heat transfer, increased fuel consumption, steam contamination and carry-over, condensate corrosion, turbine deposits and potentially lost production.

VEOLIA'S SOLUTIONS FOR TREATMENT OF BOILER FEED WATER:

Reverse osmosis

Demineralization

Continuous Electro-Deionization

Combined pre-treatment

Water Treatment Chemicals

Sea water feed

Filtration

Mixed bed ion exchange

Vacuum and forced draft degassifiers

Condensate polishing

Veolia Water Technologies designs, installs and commissions condensate polishing systems to remove impurities from the condensed turbine steam.

TREATMENT TARGETS

Reduction of suspended solids, iron and ionic impurities that lead to corrosion and downtime.

VEOLIA'S SOLUTIONS FOR CONDENSATE POLISHING

  • Candle filters
  • Pre-coated filters
  • Filtration
  • Mixed bed ion exchange
  • Deaerating feedwater heaters
  • Separate beds condensate polishers
  • TRIPOL® condensate polishing system

Cooling tower sidestream

Veolia Water Solutions & Technologies offers side stream filtration, full stream filtration, water treatment chemicals and associated services to help power generation companies effectively manage their cooling towers.

TREATMENT TARGETS

Reduce scaling and deposition that decreases heat transfer and increasing energy costs, minimize microbial activity and more specifically legionella control.

VEOLIA'S SOLUTIONS FOR COOLING TOWER SIDESTREAM

Water treatment chemicals

Side stream filtration / Full stream filtration

Turbine inlet cooling

  • Absorption chillers

Electro-chlorination

Cooling tower blow down

Veolia Water Technologies provides technologies to treat or minimize Blowdown Water. In order to avoid corrosion and organic material in cooling towers and due to excess concentration of contaminants and chemicals the Blowdown Water must be treated prior to discharge in the environment.

TREATMENT TARGETS

  • Minimise water
  • Zinc and chromates removal
  • Carbonate removal

Clarification

Filtration

  • Media filtration media membrane

Zero Liquid Discharge

Wastewater Treatment

Veolia Water Technologies provides technologies to treat or minimize wastewater from the Power Generation Industry. Flue gas desulfurization effluents require different kinds of treatments depending on the type of fuel, water sources, and environmental regulations.

TREATMENT TARGETS

  • Gypsum de-saturation and removal of particle matters
  • Removal of heavy metal
