发明名称 METHOD AND ARRANGEMENT FOR RECOVERING FIBER
摘要 The present invention relates to a method and system for recovering fibres by means of a filter surface (1) from white water (2), in which auxiliary pulp (3) is added to the white water to recover fines. The filter surface is at first brought into contact with pulp of higher consistency containing more auxiliary pulp and a filtering fibre layer having longer fibres than the fines is formed from the auxiliary pulp onto the filter surface. Subsequently, the filter surface is transferred to a zone containing more white water. The fibre layer filters fines and other fine particles from the white water.
