Claim Text:
1. An on-line analyser of macrocontaminants for a pulp and/or a white water stream having the macrocontaminants and fibrous material, the analyser comprising: a pulp classifier separating the macrocontaminants from the fibrous material in a sample of the stream into a liquid fraction comprising isolated macrocontaminants comprising light-weight and the heavy-weight macrocontaminants; a contaminant chamber enclosing a contaminant cell receiving the liquid fraction, wherein the light weight and the heavy weight macrocontaminants separate within the contaminant cell and the contaminant cell comprising a contaminant settling plate; an optical chamber comprising at least one optical detector connected to the cell capturing at least one detected image; a control chamber taking the at least one detected image and conducting an image analysis to determine type and quantity of at least one of the light-weight and the heavy-weight macrocontaminants in the liquid fraction; wherein the control chamber comprises a computer comprising a software program performing the image analysis and supervising execution of tasks of the analyser; and wherein the software program communicates with a camera dynamic link library, an imaging library, and an OPC server interacting to identify the type and the quantity of the at least one light-weight and the heavy-weight macrocontaminants.
