Measurements needed for on-line control of retention and drainage

In a retention and drainage control strategy, it is necessary to KEYWORDS monitor the concentration of dissolved inorganic material and the Chemical analysis concentration of dissolved and colloidal organic material. Conductivity is successful as a sensor to monitor inorganic material. We studied TOC as a means to monitor dissolved and colloidal organic material and found it to work well. Both conductivity and TOC have limitations, and pH, consistency, and temperature need to be controlled
