Title: Measurements needed for on-line control of retention and drainage

Author: Springer, Allan M.; Noe, Jeffrey S.; Wegner, T. H.;

Date: 1987

Source: Tappi journal. Vol. 70, no. 4 (Apr. 1987): pages 125-128.

Publication Series: Miscellaneous Publication

Description: In a retention and drainage control strategy, it is necessary to monitor the concentration of dissolved inorganic material and the 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.

Keywords: Retention, drainage, electrical conductance, conductivity, process control, paper machines, total organic carbon
