Water Modelling

The modelling of any system consists of establishing a conceptual model of behaviour that can be replicated, so that by varying the parameters that affect these systems, the results can be predicted before actual changes are made.

Thus, it is possible to model the changes that occur, for example, in an irrigation water when changing its pH, hydraulic system pressure or temperature, in order to know, for example, the possibility of a water producing calcareous incrustations in the hydraulic systems of the golf course and to act accordingly.

When Calcite or Aragonite species (calcium carbonate with different three-dimensional structures) are supersaturated in water, i.e. their saturation indexes are higher than 0.5, they are susceptible to precipitate and cause clogging in sprinklers, etc., although Aragonite does not usually give rise to precipitate nuclei for this purpose. It is therefore preferable for calcareous forms to be in the form of Aragonite rather than Calcite.

Thus we can foresee how a water with pH 7.8 removes limescale by lowering its pH to 6.5, but does not affect the precipitation of gypsum from the water.

Similarly, gypsum (calcium sulphate) can precipitate if its saturation index is higher than 0.5, which occurs less frequently than in the case of carbonates.
