Abstract
The tightening standards for environmental protection set forth in legislation and the green consideration has reduced the environmental load of the paper and pulp industry significantly during recent years. Paper mills have decreased their water consumption by increasing internal circulation and by improving external effluent treatment. The consequence is that the concentrations of organic and inorganic dissolved and colloidal substances in the paper mill waters have risen. The fresh water consumption of paper machine can be decreased by cleaning the different water streams from the wire- and press-section and by lowering the amount of organic and inorganic materials led to paper machine water. In this case also water from mechanical pulping process and pulp itself should be cleaned. In this project the water use of modern paper machine and stream connections are studied. In addition flows, interactions and retention of dissolved and colloidal materials in the wet end of the paper machine are investigated. By utilizing this knowledge accurate simulation models of paper machine wet end can be created. With this model the various methods and technologies for controlling the harmful components in paper machine wet end are analyzed. (orig.)
