THE BUILDUP OF DISSOLVED AND COLLOIDAL SUBSTANCES IN CLOSED WHITE WATER SYSTEMS
Any reduction in the paper machine water consumption in a closure of a mill white water system will be accompanied by an increase of the dissolved and colloidal solids in white water. In order to combat this buildup, a mathematical model has been developed to predict how the dissolved and colloidal substances (DCS) build up after the white water system of a paper machine was closed to different degrees. According to the model, five strategies that could alleviate the increase in DCS concentration were brought forward in theory: 1) to decrease the recycled ratio of white water in paper mill; 2) to improve the removal efficiency of DCS; 3) to boost retention efficiency of DCS in paper; 4) to reduce DCS total average concentration entering the papermaking system; and 5) to enhance DCS critical saturation.
