Diverse benefits such as reduction of fresh water consumption and effluent discharge, efficient use of raw materials and energy savings can be obtained by paper making system closure Closure of paper making processes, however. causes many problems including reduction of the efficiency of additives. decrease of retention and dewatering, felt plugging, poor paper quality, generation of slime and odor. poor vacuum efficiency, etc, and It has been recognized that accumulation of inorganic and organic substances m the process white water is the prime cause of these problems Therefore. technological developments for preventing accumulation of these detrimental substances are urgently required for Implementing paper making system closure Understanding of the accumulation phenomena of the inorganic and organic substances In the paper making process white water is prerequisite for papermaking system closure in this study a process simulation method.
was used to analyze the accumulation phenomena of anionic starch in the process white water as the closure level of a fine paper making process is increased A pilot paper machine was used as a model process Starch adsorption and desorption models were developed based on the concept of starch adsorption ratio, which was not considered m previous studies. Steady state simulation studies were carried out based on this model using a commercial simulator In steady state simulation, the variation of dissolved starch concentration in each process unit was monitored as a function of white water usage for wire shower
The result of the steady state simulation showed that dissolved starch concentration and its increase ratio m process units increased as white water usage ratio for wire shower increased.
