1. 1. REMOVAL OF LIPOPHILIC EXTRACTIVES AND MANGANESE IONS FROM SPRUCE TMP WATER BY FLOTATION

   Författare :Dariusz Zasadowski; Magnus Norgren; Anna Sundberg; Mittuniversitetet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Flotation; Foaming agents; Chelating surfactant; TMP process water; Pitch control; Internal cleaning stage;

   Sammanfattning : Dissolved and Colloidal substances (DisCo) and metals are released from wood during thermomechanical pulp (TMP) production. The mechanical treatment causes that these components have a tendency to accumulate in process waters, as the water circulation systems in integrated paper mills are being closed. LÄS MER
