Water quality control, keep your plant chemistry in balance

Overcoming corrosion and scaling issues while ensuring the integrity of your water/ steam circuit

Water quality control within power plants maintains the operational efficiency and minimizes plant downtime caused by corrosion or preventative maintenance. It also allows turbine supplier warranties to remain applicable. The integrity of the components is affected by the constant contact of the water and steam with metal surfaces, which creates corrosion and scaling. You need smart instrumentation for analysis, allowing you to prevent such situations and avoid expensive repairs.

A standardized solution for sampling and analysis

The modular Steam and Water Analysis System (SWAS) provides all necessary measuring signals for process control. On an analysis rack (wet rack), the samples are first extracted from the water/ steam circuit and conditioned (cooling, pressure reduction). The conditioned sample can be analyzed for various parameters such as pH, dissolved oxygen, silicate, sodium, and cationic or differential conductivity.
