Abstract:The physical-chemical characteristics of dissolved and colloidal substance(DCS) in recycled OCC pulp were studied and removal of the DCS by steam explosion and agglomeration-magnetic separation was investigated. The influence of metal ions on the stability of DCS was discussed. The results showed that DCS removal efficiency of agglomeration-magnetic separation treatment was better than the steam explosion process, DCS content, DCS average particle size, conductivity, turbidity, CODCr of the effluent decreased,while Zeta potential increased. In addition, the stability of the DCS in the OCC pulp often was improved.
