Use of a treated surface calcium carbonate in water purification and / or for drainage of sludge and sediment and resulting composite material |
| abstract |
Use of a treated surface calcium carbonate for water purification and / or drainage of sludge and / or sediment, in which at least 1% of the accessible surface area of calcium carbonate is covered by a coating comprising at least one cationic polymer, in which the treated surface calcium carbonate comprises a modified surface calcium carbonate that has been processed with cationic polymers through an additional treatment step, and in which the calcium carbonate of Modified surface is obtained by reacting a natural calcium carbonate and / or a precipitated calcium carbonate with an acid and with carbon dioxide before the preparation of the treated surface calcium carbonate, in which the carbon dioxide is formed in situ by treatment with acid and / or supplied from an external source. |
