The problem was the presence of Total Organic Carbon (TOC) in the surface water released by oxidation and not retained by the existing resin demin plant; it decomposes at the high pressure boiler working conditions and increases the conductivity of the produced steam.
This increase in conductivity put the quality of the produced steam above the design limits of the turbine specifications, so it couldn’t be commissioned.
An urgent, reliable and flexible solution was required to produce as soon as possible the correct steam quality, so enabling the commissioning of the turbine and to start electricity production.
The solution proposed by SUEZ consisted of a fully automated mobile water installation, delivered in very quickly, and able to treat the contaminated demin water at very high flow and with limited waste water production.
SUEZ set up a mobile installation consisting of cartridge filtration and reverse osmosis to treat up to 130 m³/h of flow per unit, with a recovery rate up to 95%.
With this mobile solution, SUEZ was able to remove the TOC necessary to keep the steam conductivity below its design limitation levels.
- Ability to continue the commissioning of the turbine & power plant
The proposed solution by SUEZ allowed the client to finish the overall commissioning of the turbine & power plant within the scheduled timeframe.
- Ability to evaluate technical solution
The SUEZ solution allowed the customer to test and validate the treatment line as a pilot trial and to approve the best technical solution before building a permanent treatment plant.
Treatment of contaminated rain waters before discharge.
Treatment of stored industrial contaminated waters before discharge.
Treatment of contaminated ground waters before re-use.
