    The process of transformation from vaterite to calcite, which is important to produce stable crystals, occurs via a spontaneous reaction through either simple contact with water or heating. Accordingly, if there are any metal ions on the surface of the vaterite, the transformation process may be delayed or stabilized (Nassrallah-Aboukais et al

  • Water utilities circular: the reuse of softening pellets

    In this improved softening process, the normally used sand is replaced by a calcite seeding material. The residual from this new process becomes then an almost pure calcite, which is centrally processed in ‘The Calcite Factory’ into new seeding material (so circular) and raw material(s) for other economic sectors.
