Carryover and its Causes - forbesmarshall.com

In boiler water, the presence of free NaOH must be eliminated by practicing coordinated phosphate control. High alkalinity and presence of suspended impurities increase carryover. When the suspended impurities are more, there is a blanket formation over the water-steam interface and this prevents the easy passage of steam bubbles from the

Environmental Monitor | What is Conductivity?

Salinity and conductivity measure the waters ability to conduct electricity, which provides a measure of what is dissolved in water. In the SWMP data, a higher conductivity value indicates that there are more chemicals dissolved in the water. Conductivity measures the waters ability to conduct electricity. It is the opposite of resistance.
