| Zusammenfassung: | The present invention relates to at least one surface-reacted calcium carbonate- comprising mineral material and/or a surface-reacted precipitated calcium carbonate that is/are coated with at least one anionic polymer to obtain a surface-coated calcium carbonate-comprising material as well as to a process for the preparation of the surface-coated calcium carbonate-comprising material. Furthermore, the present invention relates to a process for the purification of water and/or dewatering of sludges and/or suspended sediments and to the use of a surface-coated calcium carbonate-comprising material for water purification and/or dewatering of sludges and/or suspended sediments. |
