Pre RO

Make-up water is central to the steam cycle, replenishing water to the steam condensate cycle as needed to maintain the water inventory of the cycle. Systems often include an RO (reverse osmosis) unit as the first stage treating raw water, and some make-up systems may include a carbon vessel or ultra-filtration when necessary. Sources will vary and may include well water and surface waters such as rivers and lakes, thus water quality varies as well. The application includes water for BWR (Boiling Water Reactor) and PWR (Pressurized Water Reactor) nuclear plants. Make-up water is typically added to a condensate storage tank and then directly to the water cycling to the Reactor in a BWR plant and to the water cycling to the Steam Generator in a PWR plant. In a fossil fuel power generation facility, the condensate storage tank adds to the water cycling to the boiler. This is also accomplished in co-generation facilities and industrial plants that have an on-site power generation system.
