Abstract:

In this work, authors proposed an iterative procedure to modify the chemical-physical properties of aqueous solutions with high ionic strength. According to the experiments performed, perturbation was induced by the use of a peristaltic pump. The effects of chemical-physical operating parameters studied were the water electrical conductivity (χ), the hardness and the pH. A very significant decrease in χ and a significant increase in pH were observed. In addition, the formation of abundant white precipitates of carbonates was observed, with the consequent reduction of the water hardness. In this system, the reduction of water hardness was demonstrated to depend on the normal mechanism of chemical precipitation of the carbonates at pH larger than 8 related to the use of pumping procedure. This iterative procedure stabilized electrical conductivity at about 300 µS/cm, indicating a dynamic equilibrium. Results suggest peristaltic pump perturbation promotes the formation of structured water aggregates, affecting ion mobility and solution properties.

Keywords: water stable structures, peristaltic pump, electrical conductivity, hardness of water.
