摘要 |
With the aid of hydrocyclones, relatively light and heavy contaminants are separated from a pulp suspension. According to the invention, at first light contaminants are separated from the pulp suspension and the fibre concentration of the pulp suspension is substantially increased by means of a first multihydrocyclone unit (6) comprising a multiplicity of parallelly coupled hydrocyclones designed for separating light contaminants, and thereafter heavy contaminants are separated from the pulp suspension with the increased fibre concentration by a second multihydrocyclone unit (13) comprising a multiplicity of parallelly coupled hydrocyclones designed for separating heavy contaminants. |
