Water quality monitoring with SWAS, efficient and reliable
Protect your water-steam circuit by reducing scaling and corrosion risks
Water quality monitoring within power plants is an essential activity both in maintaining operational efficiency and minimizing downtime caused by corrosion and leakages. Constant contact with water and steam raises the risk of corrosion and scaling on all metal surfaces. With the right instrumentation for water quality measurement and analysis such risks can be offset, and costly repairs avoided.
How we can help
Providing all the necessary measuring signals for process control, the Endress+Hauser Steam and Water Analysis System (SWAS) offers a standardized solution for the convenient sampling and analysis of water within power plants, reducing downtime and increasing plant efficiency. Modular, scalable and easy to retrofit, plus suitable for use with Memosens digital technology e.g. for easy calibration, SWAS provides reliable measurement, user friendly maintenance and minimized downtime.

Applications
Avoid system corrosion with pH monitoring
Feed-water pH has a direct impact upon corrosion levels in the water-steam circuit, and pH values can vary depending on the location in the circuit itself. To prevent corrosion, plant operators therefore need to carefully monitor pH and implement conditioning according to one of two modes depending on the installed equipment, either universal or more commonly slightly alkaline.
Chuyên môn của chúng tôi trong lĩnh vực
Endress+Hauser offers unique sensors and transmitters for high-quality pH measurement at multiple points in the water-steam circuit.
Monitor pH levels reliably even in highly alkaline media or hazardous areas with our Orbisint CPS11D glass electrode based on Memosens technology
Optional salt ring for low conductivity applications in deionized water such as boiler feed water
Silica can deposit on any surface steam touches, leading to a solid layer on turbine blades and causing abrasion and blockages. Removing silica deposits with chemicals or mechanical processes can cost valuable time and resources.

Endress+Hauser analyzers offer continuous silica monitoring at multiple points in the water-steam cycle.
Prevent corrosion with Dissolved Oxygen (DO) monitoring
Oxygen can result in corrosion damage to the components of the water-steam cycle and must only be present in trace quantities (ppb). Under alkaline operating conditions, mechanical de-aeration and chemical scavenger additives are needed to remove the DO and to minimize corrosion.

Minimize process downtime during sensor exchange thanks to automatic sensor recognition
Avoid scaling through detection of conductivity variations
Dissolved solids present in the water-steam cycle can create scaling on equipment and technical failures. The conductivity of pure water is almost zero and even a small amount of salt can increase corrosion dramatically, therefore the conductivity parameter is a useful indicator of dissolved solids and impurities caused e.g. by cooling water and air leakages, and the likelihood of scaling.
