Abstract

Relatively heavy contaminants are separated from a contaminated pulp suspension by pumping the latter through a multihydrocyclone unit (6) having a multiplicity of hydrocyclones. Each hydrocyclone is provided with turbulence creating means adapted to counteract the formation of fibre network in radially outer liquid layers in the hydrocyclone. The pulp suspension separated from heavy contaminants is dewatered in a pulp wet machine (2). According to the invention, the fibre concentration of the pulp suspension which is fed into the multihydrocyclone unit (6) is at least 0,9 %.
