摘要： The invention relates to a limewater composition including slaked lime particles suspended in an aqueous phase. Said composition is characterized in that said slaked lime particles have a particle size defined by a narrow and monomodal profile for particle size distribution. The invention also relates to the method for obtaining said limewater composition.

摘要： System for membrane fouling control comprising: a first conduct portion (2); a second conduct portion (3); a membrane (1) arranged between the first conduct portion (2) and the second conduct portion (3) to filter a liquid by conducting it from the first conduct portion (2) to the second conduct portion (3), wherein the membrane (1) has a defined pore size; and a fouling control means (4) filled with a membrane fouling control additive with fouling control particles (6) and configured for adding the membrane fouling control additive in the first conduct portion (2) so that a dynamic protective layer (7) is formed on the membrane (1) by the fouling control particles (6) for protecting the membrane (1) from foulants (10), wherein the d 10 of the size distribution of the fouling control particles (6) is larger than the defined pore size and the d 90 of the size distribution of the fouling control particles (6) is smaller than or equal to 20 µm.

摘要： A mineral composition made from a mixed solid phase of calcium and magnesium carbonates, method of preparing same and use thereof. A mineral composition made from a mixed solid phase of calcium and magnesium carbonates, formed from a crystallised calcium portion and a crystallised magnesium portion in the form of platelets, the crystals of the calcium portion and those of the magnesium portion being aggregated in the form of composite aggregates, said aggregates themselves being at least partially agglomerated, said calcium portion comprising at least one carbonate chosen from the group consisting of calcite, aragonite and the mixtures thereof, said magnesium portion comprising hydromagnesite in platelet form, said mixed solid phase having a bulk density less than or equal to 250 kg/m
3 , and greater than or equal to 80 kg/m3, measured according to standard EN 459.2.
