Boiler feed water treatment continued

For some applications, notably feed-water treatment for high-pressure boilers, removal of oxygen is essential. For most industrial purposes, however, de-aeration is not applicable, since the water used is in continuous contact with air, from which it would rapidly take up more oxygen. Attention must therefore be given to creating conditions under which oxygen will stifle rather than stimulate corrosion. 

Conductivity sensors A very significant parameter that gives a measure of the concentration of ions in industrial process streams is conductivity. The continuous measurement of conductivity in process streams is a common practice in the monitoring of boiler feed water, brackish water, demineralization, industrial process media, municipal and industrial wastewater, surface waters, and water treatment. Specific areas of application for conductivity sensors include control of drinking water and ultrapure water quality, determination of nonspecific contaminants, monitoring of salt load in wastewater...
