WHAT IS THE PRINCIPLE OF OPERATION OF DELTA DEVICE?
All crystallization events require that a THERMODYNAMICS DRIVING FORCE exists. In the case of carbonate scale from hard water this driving force can be expressed as a ration of the CONCENTRATION of CALCIUM IONS and CARBONATE IONS in the water to their concentration in water EQUILIBRIUM with scale crystals. This is termed as the SUPER-SATURATION RATIO. If its value is greater than one, scaling can occur, and if the value is less than one. Any scaling will tend to dissolve. The parameters that control the super-saturation ratio for CaCO3 are the water composition i.e. hardness, alkalinity, pH, etc., temperature and pressure. The mechanisms by which DELTA Device can alter the super-saturation ratio of the water locally, and which therefore, affect this precipitation are scientifically proven. a) The DELTA Device alloy adsorbs positive ions, which in the case of hard water are predominantly calcium ions, into the layer of water in contact with the DELTA Device. In order to retain overall n
