Conductivity of demineralized water
WebWhen exchangers approach their end point, silica usually is the first impurity to "break through" into the effluent. For this reason, silica is a critical quality control parameter in demineralized / ultrapure water treatment. Conductivity measurements, long used as a measure of water purity, are unreliable in detecting resin bed exhaustion ... WebNov 30, 2024 · As the demineralization of water is a minerals removing process and the electric current is related to minerals, therefore the demineralized water has a very low electric conductivity. It has no …
