    Main Factors To Increase The Conductivity Of Bleaching And Dyeing Wastewater
    Jun 09, 2018

    The conductivity of the pre treatment oxygen bleaching stage is low: after the dyeing begins, the conductivity rises gradually. With the addition of the anhydrous sodium sulfate, the conductivity rises rapidly. When the soda ash is all added, the conductivity reaches the highest peak. It can be seen that sodium sulfate and soda ash are the main factors leading to the increase of electrical conductivity of waste water.
