Water treatment plant
Task
New water treatment plant design,
production, installation, and commissioning
Water source
Surface (lake) water
About the project
There are two water treatment plants in this power plant. One is for the
surface (lake) water treatment. It provides softened water for the heating
network and deionized water for high-pressure boilers. The second one is
for condensate polishing. The plant is designed for contaminated steam
condensate treatment to reach deionized water parameters.
Surface (lake) water treatment line
Ultrafiltration -> Softening -> Membrane degasification -> Reverse
Osmosis -> Electrodeionization -> Ion Exchange (Mixed Bed filters)
Condensate treatment line
Heat Exchangers -> Activated Carbon ->
Oil products separator -> Mixed Bed filters
Summarize
There were used advanced water treatment technologies in this project.
The challenge in implementing the water treatment plant in this power plant was its on-demand operating
mode. On-demand operation of membrane technology equipment has complex issues. Despite that, the
water treatment plant is operating reliably and provided system parameters meet requirements.
