BOILER DISSOLVED OXYGEN CONTROL
types, the scrubber unit can tolerate operation over a wider load range (typically 20-120% of design) than the tray unit (typically 40-100% of design) which can tolerate more cold water. The tray unit is generally the choice in the bigger units that operate under constant load as in major electrical generating stations.

TOTAL DISSOLVED SOLIDS MEASUREMENT - IC Controls
iccontrols.comTotal Dissolved Solids Definition: Total Dissolved Solids (TDS) is a measure of the sum of all inorganic and organic substances in a liquid in molecular, ionized or micro-granular colloidal suspended form. The solids must be small enough to survive filtration through a sieve the size of two micrometer. TDS solids are normally found in all ...
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.
