TOTAL DISSOLVED SOLIDS MEASUREMENT
Water treatment chemicals and dispersant can cause significant variations specific to each plant. In the more concentrated boiler water the solids content factor typically is found between 0.55 and 0.9 ppm TDS per µS/cm. The water treatment company should be consulted and periodic gravimetric TDS tests done to confirm the solids content factor ...

BOILER DISSOLVED OXYGEN CONTROL
iccontrols.comDissolved Oxygen removal from any steam and water system is of major importance. The first step is typically mechanical deaeration which is economical and serves to also eliminate other corrosive gases such as ammonia and carbon dioxide. A properly operated deaerator can reduce dissolved oxygen to as low as 10 µg/L (10 ppb). Note: 1 µg/L = 1 ppb.
High Purity Water Resistivity/ Conductivity Measurement
iccontrols.comHigh Purity Water Resistivity/ Conductivity Measurement Ultra-Pure Water without any chemical impurities will still have a conductivity because of the presence of H+ and OH-ions due to the self-ionization of water. Ultra-pure water has a conductivity of 0.055 µSiemens/cm or a resistivity of 18.18 mΩ·cm at 25 °C.

byworth.co.ukGenerally it is desirable to have a slightly high pH for boiler feed water. Ideally the feed water should be in the range of pH 8.5 – 9.5. This ensures that free carbon dioxide within the system becomes ‘fixed’. If copper fed lines or heaters are used, restrict the feed water pH to …

ssu.ac.irSome feed water treatment chemicals, such as chelants, if not properly applied, can corrode feed water piping, control valves, and even the boiler internals. While the elimination of oxygen from boiler feed water is the major step in controlling boiler corrosion, corrosion can still occur. An example is the direct
